Arm exercises after breast cancer surgery

When can you start arm exercises after breast cancer surgery?

Your own surgical team sets the start date. There is no national day number to give you: NICE NG101, the UK guideline, asks the breast unit to explain when the exercises should be started and leaves the detail to local protocols, which means the day is a property of your hospital and not of the operation. If nobody has told you, ring and ask. That is also a fair question to ask before the operation, when there is time to answer it.

Two numbers circulate and neither is a recommendation. A Cochrane review of ways to prevent arm swelling counted a start seven days after surgery as the delayed one, and compared it with starting earlier (Stuiver 2015). The PROSPER trial brought its exercise program in at 7 to 10 days after surgery, with further appointments at one and three months (Bruce 2021). Those are descriptions of what the research did, which is a different thing from advice about what you should do, and a leaflet from another hospital is not your protocol either.

What the Cochrane review found is worth knowing while you wait for that answer. Across three studies of an early versus a delayed start, 378 women between them, the pooled relative risk of lymphedema after an early start was 1.69, with a confidence interval running from 0.94 to 3.01, and the authors concluded that the evidence does not indicate a higher risk of lymphedema from starting shoulder exercises early. Both halves of that are true at once, because an interval that wide includes no difference and also includes a threefold increase, so the number settles nothing in either direction. It is a reason to keep to the start date your unit sets rather than bring it forward on your own, and it is not a reason to put off a start your unit has already cleared.

The movement side of the same comparison went the other way. Forward flexion, which is lifting the arm in front of you, was better at one and six months in the early starters, although the studies were too different to pool. At 12 months the one study that measured it found no difference in shoulder movement or in what people reported about their own arm. The evidence overall was judged low quality and the search ran in 2013, so this is a careful signal and not a settled answer.

There is a reason to defer to your unit beyond politeness. One of the two studies in that review that measured fluid from the surgical drains reported more of it in the people who started early. Your team knows what your wound, your drains and your operation were, and nobody writing a web page does. If your drains are still in, ask what the arm may do while they are there instead of taking a number off a page, and use the warning list if the drain site or the fluid in it changes.

NG101 is the only national guideline we found that deals with the arm and shoulder after breast cancer surgery, and it is British. Australia's main consumer health site carries a breast cancer page that does not mention the shoulder once. That is not a reason to treat NG101 as irrelevant outside the UK: it is a reason to take its risk list to your own team and ask where you sit on it.

What makes a shoulder problem more likely after breast cancer surgery

NG101 names the things that put someone at higher risk of an arm and shoulder problem, and it is the most useful list on this page, because it is how you find out whether you are the person the supervised physiotherapy recommendation was written for.

• A shoulder that was already a problem: previous surgery on it, a fracture or dislocation, a frozen shoulder, osteoarthritis or rheumatoid arthritis in that shoulder, or shoulder pain with no clear cause, stiffness or loss of function.
• A body mass index over 30 kg/m2.
• A planned clearance of the lymph nodes in the armpit (axillary node clearance).
• Planned radiotherapy to the armpit, or to the nodes above the collarbone (supraclavicular nodes).

NG101 then adds the group everyone forgets. If a node clearance, or radiotherapy to the armpit or those nodes, was not planned but was decided on after your operation, you move into the same higher risk group. Your risk level can therefore change weeks after the plan you were discharged with was written, and the plan does not update itself.

For people at higher risk, NG101 says to offer supervised support for arm and shoulder mobility, and for everyone else to consider it. It also sets out what that support should look like, which is useful to know before you are told what is available: individual, group or virtual, depending on your circumstances, needs and preferences; tailored to you, with the exercises modified where your needs are more complex; including a check that you are doing the movement correctly; and delivered by physiotherapy staff or other appropriately trained allied health professionals. A further recommendation asks for a referral to the physiotherapy department for assessment and treatment where arm and shoulder mobility stays reduced after breast cancer surgery or radiotherapy. In practice the list above is what you quote when you ask for that referral.

Which operation you had, and what it leaves the shoulder

What is written on your operation note matters more here than anything else on this page, because four different operations send people to the same set of exercises.

A wide local excision, often called a lumpectomy, takes the lump out with a margin of tissue around it and leaves the chest wall and the armpit largely alone. A mastectomy removes the whole breast and lifts the skin off a wide area of chest wall, so the closure is under more tension and lifting the arm pulls on more of it in the early weeks. A sentinel node biopsy takes the first node or two that the breast drains to, through a small cut in the armpit. An axillary node clearance opens the armpit and takes the nodes out of it, and that is the operation that changes the arm. A risk-reducing (prophylactic) mastectomy is the same mastectomy done for a different reason, and it has its own note below.

The ALMANAC trial put numbers on the difference between those last two. It randomized 1031 women with early breast cancer to a sentinel node biopsy or to standard axillary treatment, which in that trial meant a clearance, or axillary radiotherapy at the centers that worked that way. At 12 months, 5 percent of the sentinel node group had any lymphedema against 13 percent, and 11 percent had loss of feeling against 31 percent. Arm function and quality of life were better in the sentinel node group throughout, drains were needed less often and women got back to their usual activities sooner (Mansel 2006).

That gap is why advice written for a clearance is heavier than a sentinel node biopsy needs, and why advice written around a sentinel node biopsy is too thin for a clearance. PROSPER, the trial most of this page leans on, recruited at the clearance end: 83 percent of those women had one.

What none of that gives you is a day or a weight, and the reason is worth knowing. Early restrictions are set by the wound and the armpit rather than by the shoulder joint. A fresh surgical wound is held by its stitches at first and by its own new tissue later, so it is at its weakest in the first couple of weeks, which is where most of the restrictions sit. The armpit is also where fluid collects after node surgery, and how much the arm moves is one of the things that affects how much collects, which is the drainage signal in the Cochrane review above. Those limits come off on your unit timetable and not when the arm feels ready.

If you had a risk-reducing mastectomy and have never had cancer

This page is for you as well, and it says so here because nothing else on it does. NICE CG164, the UK guideline on familial breast cancer, has a section on risk-reducing mastectomy for women with no personal history of breast cancer: it asks for bilateral mastectomy to be raised as an option with everyone at high risk, for genetic counseling before the decision, and for reconstruction, immediate or delayed, to be discussed with the surgical team that would do it. It names BRCA1, BRCA2 and TP53 among the mutations it is written for. What was done to your chest wall is the mastectomy described above, the reconstruction section below is yours, and so is every stage of the program.

Two things read differently for you. The nodes in your armpit are usually left alone, so the node surgery numbers above describe a bigger operation than yours, and every trial quoted on this page recruited women treated for breast cancer, so none of their results is about you. And a few of the warning signs at the foot of this page open with "if you have had cancer, now or in the past". Those few are not yours, and they are the only ones that are not. The rest are: the wound, the drains, the reconstruction, an arm that is swelling, a blood clot, and a new lump or a change in the skin, the scar or the chest wall, which goes the same day to the surgical team that operated on you, exactly as that line says.

If you have had a reconstruction

The main evidence on this page was not collected in women who had one. PROSPER recruited after non-reconstructive breast cancer surgery, so none of its numbers describe a rebuilt breast, and the stages below assume somebody has cleared the range and the load. In each of these four situations the limits belong to the team that did the reconstruction, and this page cannot stand in for them.

• A tissue expander or an implant under the chest muscle. The pectoral muscle has been lifted off the chest wall to make the pocket, and arm movement pulls on it while it heals. A systematic review of 29 studies found that women with implants under the muscle reported worse arm symptoms and function than before their surgery, and worse than women whose implants sat in front of the muscle (Carr 2025). Which side of the muscle yours is on is a fair thing to ask.
• A latissimus dorsi flap. One of the muscles that works the shoulder has been moved: the latissimus pulls the arm down, back and inward, which is a large part of what a resistance band row asks of it. A meta-analysis of 26 studies and 1045 women found flexion and abduction measurably reduced at three months or earlier, and concluded that the flap does affect shoulder function, usually by a small amount, with the published evidence too weak to settle it (Steffenssen 2019). In the patient-reported review above, latissimus reconstruction carried the highest reported arm impairment of the reconstruction types (Carr 2025). No published protocol says what a transferred latissimus may pull against in your eighth week, so ask your plastic surgery team for your own limits on pulling and lifting with that arm, and ask about the band row and the prone Y raise by name.
• An abdominal flap (DIEP or TRAM). The breast has been rebuilt from tissue taken from the tummy, and the limits that matter are the abdominal ones. They come from your team.
• Any flap or implant, in the early weeks. Lying face down presses on the rebuilt breast, so prone work is something to clear rather than something to judge by comfort.

Reconstruction also adds its own problems to watch for, and they are on the warning list: skin or flap tissue that changes color or goes hard, a wound opening over an implant, a rebuilt breast that swells quickly or turns hard and more painful, and a collection of fluid at the back or the tummy where the tissue was taken. None of those is a rehabilitation problem.

What arm exercises do you do, and how often?

Three stages, in the order the arm usually gets them back: supported movement, then movement under its own power, then strength. The program below follows that order, and every exercise page gives a starting dose with the detail of the technique.

Early on, the movement exercises are often done more than once a day in short spells, which suits a shoulder that stiffens between sessions. As a rough guide, the assisted range exercises here use around 10 to 15 slow repetitions, 1 to 3 times a day. Stage 3's loaded work goes the other way, and this is the part people get wrong at home: the two band exercises and the prone Y raise are 2 to 3 sets of 8 to 15 repetitions, two or three sessions a week with a day off in between, not one every day. That is the frequency the international roundtable on exercise for cancer survivors sets for resistance training in women with or at risk of lymphedema after breast cancer (Campbell 2019), the trial in women who already had lymphedema lifted twice a week (Schmitz 2009), and a rest day is the only thing that lets the next-day rule below tell you anything.

The isometric hold is not loaded the same way and keeps the numbers on its own page. Where an exercise page sets its own repetitions, use those and keep this frequency. Your physio will adjust all of it, and the numbers on your unit's own sheet come first. If you have neither a sheet nor a physio yet, ring your breast care nurse and ask for both, and for the three numbers that decide the stages: when to start, how far the arm may go, and when you may load it.

How to use this program

Start with the stage your team has cleared, not the stage the arm feels ready for. If you have been given a limit on how far the arm may lift or how far it may go out to the side, that limit decides the stage, and the way round it is to ask for it to be reviewed, not to go past it quietly.

One thing to settle before you start at all. If your arm or hand is swollen now and nobody has looked at it yet, get that assessed first rather than starting the program to see whether it settles. The section on lymphedema below says how quickly, and which swelling needs emergency help.

Some discomfort as a stiff shoulder moves is normal. The level to work at is discomfort that settles soon after you stop and leaves the arm no worse the next morning. Pain that is still there the next day, or an arm that looks puffier or feels heavier or tighter afterward, means the session was too much, and the warning signs on this page say which of those needs checking rather than adjusting.

Breathe normally through every repetition rather than holding your breath. Four of these exercises use a stick, and the precautions on those pages about operations at the shoulder or the elbow still apply: if you have had one, that team's limits come before anything here.

Exercise after cancer treatment is safe for most people and inactivity is the thing to avoid, which is the conclusion of an international roundtable on exercise for cancer survivors, with enough evidence to say that the right doses improve fatigue, physical functioning, anxiety, depressive symptoms and quality of life (Campbell 2019). Arm rehabilitation sits inside that wider picture. Check with your doctor first if you have a heart or lung condition, or blood pressure that is not under control.

Two groups the same roundtable deals with separately, because the usual advice is not written for them. If you have been told there is cancer in your bones, you are in the group it says needs a medical assessment and a doctor's clearance before exercising, with the program then set around where the lesions are by a rehabilitation specialist or a trained exercise professional. The ribs, the spine and the upper arm bone are among the common sites, so that applies to arm exercises and loading as much as it does to running or lifting from the floor. And if you already have lymphedema, or have been told your bones are thinner than they should be (osteopenia or osteoporosis), it asks for a medical check first and the exercises adjusted to what that finds. The roundtable also says bone pain can be the first sign of a lesion in bone, and it tells exercise professionals to send anyone who reports new pain back to their medical team before carrying on, so pain the exercises do not explain, pain that is there at rest or at night, or pain that keeps getting worse is a reason to stop the program and be checked rather than to work around.

The clearance comes first because a bone with a lesion in it can break under a load that would not normally break it, and the upper arm bone is the bone these exercises load. A row and an overhead lift both send a bending and twisting force through it. This is the one situation on this page where the limit on load, and not only the limit on range, has to come from the people who know where your lesions are, and they may want the bone itself looked at or treated before you load it at all.

The exercise program

The exercises below carry their own stop signs and precautions. Open the line under an exercise and read them before you try it.

Will arm exercises cause lymphedema?

This is the question underneath all the others, and the guideline answer is more reassuring than most of the advice still in circulation. NG101 states that physical activity may improve quality of life and that there is no indication that physical activity causes, or worsens, lymphedema.

The same section of NG101 goes further and lists things people are routinely warned off, with the evidence not supporting the warning. There is no consistent evidence of increased risk from air travel, travel to hot countries, manicures, hot tub use or sports injuries. Nor is there consistent evidence of risk from medical procedures on the treated side, which includes blood tests, injections, drips and having your blood pressure taken. NG101 still asks for the use of that arm to be a shared decision with the clinician in front of you rather than an automatic yes or no. These are 2025 amendments, so if you were told something different a few years ago, you were told what was then being said.

NG101 also says not to offer compression therapy as a way of reducing the risk. Read that narrowly. It is about preventing lymphedema in someone who does not have it, and it says nothing about a garment you have been given to treat swelling you already have. If you have lymphedema, your lymphedema team's instructions about your sleeve stand, and the trial that tested weight lifting in women with established lymphedema required a well-fitted compression garment while lifting (Schmitz 2009).

The trial evidence on loading the arm points the same way as the guideline. In the Cochrane review, two studies compared progressive resistance training with restricted activity and found a relative risk of developing lymphedema of 0.58, with a confidence interval from 0.30 to 1.13 across 358 participants, which is a result that leans toward exercise without excluding no difference. The authors attached a condition to it, that symptoms are closely monitored and adequately treated if they occur. That condition is not decoration. It is the reason this page gives you warning signs to watch and a route for each of them.

Swelling is not the only thing to keep an eye on. One of those two studies also measured pain, and the resistance training group reported pain more often at three months and at six months than the comparison group. An arm that is sore between sessions wants its load dropped rather than its sessions pushed through.

Then there are the two PAL trials, which are the numbers almost nobody quotes. One randomized 154 women who were 1 to 5 years past surgery, had at least two nodes removed and had no signs of lymphedema, and new lymphedema appeared in 11 percent of the weight lifting group (8 of 72) against 17 percent of the controls (13 of 75). Read that gap carefully, because the interval around it runs from 17 percentage points fewer cases to 5 points more: the trial was built to show that lifting did not increase lymphedema rather than that it prevented it, and that is what it showed. In the group who had five or more nodes removed the gap was wider and did not include no difference, 7 percent (3 of 45) against 22 percent (11 of 49), although that is a subgroup and so weaker evidence than the trial as a whole. In the separate trial of 141 women who already had stable arm swelling, an increase of 5 percent or more in limb volume occurred in 11 percent of the lifters and 12 percent of controls, and flare-ups of lymphedema were less common in the lifters, 14 percent against 29 percent.

Those results come with their population attached, and the population is the part that stops them being a permission slip. The at-risk trial recruited women who were 1 to 5 years past their surgery, and its program ran for 13 weeks with supervision before nine months of unsupervised training with a gym membership. In the trial of women who already had swelling, a well-fitted compression garment was worn for the lifting. Neither of them says anything about what to lift in your third week, which is why stage 3 waits for your team.

The roundtable puts the limit more plainly than the trials do. A progressive resistance program on the large muscle groups, two or three times a week, start low and progress slow, is safe in women with or at risk of lymphedema after breast cancer when a fitness professional supervises it, and there is not enough evidence to say whether starting one without supervised instruction is safe (Campbell 2019). Stage 3 at home is an unsupervised start, so that sentence is about you. It is the reason to go up by the smallest step your equipment allows, and to get someone to watch the first sessions if there is anyone who can.

One situation comes before any of that, whether you are at risk or not.

New swelling that nobody has checked yet needs a doctor's assessment before you start, and the same day if it is in one arm or leg and you do not know the cause, or it is severe, painful or came on very suddenly. Call emergency services if swelling comes with shortness of breath, a chest that feels tight, heavy or painful, coughing up blood, a pounding heartbeat, or feeling lightheaded, faint, confused, sick or clammy. Sudden shortness of breath, chest pain or coughing up blood also needs emergency services when the swelling looks no different, as these can be signs of a blood clot in the lungs.

A word about the arm after surgery to the nodes in the armpit. Numbness in the armpit, or along the inner side of the upper arm, is common after that operation, and if your team already knows about yours, it is not a new warning sign. The nerve that supplies the skin there (the intercostobrachial nerve) runs straight through the area the surgeon has to work in, and a meta-analysis of axillary surgery studies found that a change in feeling in that patch is far less common when the nerve is spared than when it is divided, and that it is usually reduced feeling rather than extra sensitivity (Warrier 2014). Numbness that is new or spreading, pins and needles that stay after you stop, and weakness that is getting worse all follow the warning list instead.

Lymphedema treatment itself is a separate subject and is not covered here. Our lymphedema breathing and arm rotation for lymphedema pages carry the technique for the movements those routines use.

Cording after breast surgery, and what to do about it

Cording, or axillary web syndrome, is the tight cord you can sometimes feel or see running under the skin from the armpit, often along the arm toward the elbow crease and sometimes further (Gonzalez-Rubino 2023). It is identified by looking and feeling rather than by a scan (Yeung 2015), and what people usually notice first is that the arm stops short of where it was going, with a band standing out under the skin as the arm lifts. Pain with it is common, and lifting the arm out to the side is usually more restricted than lifting it in front (Yeung 2015). It is one complication among several, so a shoulder that will not lift is not automatically cording.

A systematic review of 37 studies found that most of the studies in it reported cording appearing within eight weeks of the operation, that it can also turn up more than three months later, and that the symptoms usually settle within three months, although in some people they carry on (Yeung 2015). That is the main reason not to go at a cord hard: in most cases you are working alongside something that is on its way out anyway.

How common it is has not been settled. The figures published for the same group of patients vary so widely that they cannot all be describing the same thing, so this page gives none. A number you meet elsewhere may be accurate for the group it was measured in and still tell you nothing about your own odds.

The physiotherapy evidence is thin and worth describing honestly. A systematic review and meta-analysis screened 188 articles and included 9 studies (Gonzalez-Rubino 2023). Exercise and stretching came out as the most effective of the approaches tested for restoring movement, reducing pain and improving quality of life, with manual therapy, scar massage and myofascial release described as possibly helpful but with worse results. The only outcome with a reduction the authors called significant was pain, at a standardized effect of 0.82 in favor of treatment, with an interval running from 1.67 in favor to 0.03 the other way, drawn from the only three studies that measured it, all of them small. An interval that crosses zero does not support a confident claim, so treat this as a small and uncertain benefit from the most studied approach, not a proven treatment.

What that means in practice is unglamorous. Gentle stretching inside comfort is the approach with the most behind it, and pulling hard on a cord that hurts is not a stronger version of the same thing. If a cord is painful, is stopping the arm moving, or you are not sure that is what you are feeling, show it to your breast care team or a physiotherapist instead of working on it alone.

How much can you lift, and when

Nobody can give you a weight from a guideline, because there is not one. The restrictions people are sent home with vary between units and are not in NG101 at all, so the weight limit a friend was given is her hospital's rule and may not be yours. Ask for yours in writing if you can.

Where there is evidence, it is about method rather than a number. The PAL trials progressed load slowly from a low start, with supervision at the beginning, and watched for symptoms between sessions. That shape is reproducible even without a gym. Start with a load you can control for the whole set with no change in the arm by the next day, go up by the smallest step your equipment allows, and change one thing at a time so that if something flares you know what did it. A full one liter bottle of water weighs about 1 kg, or 2.2 lb, which is a useful scale for how small the first steps should be.

Going back to the gym is a plan, not a date. Your team clears loading, you rebuild rather than resume, and you judge each step by the following day. If you have lymphedema, talk to your lymphedema team about your garment before you start, for the reason in the previous section.

Radiotherapy and why your risk level can change after surgery

Radiotherapy to the armpit or to the nodes above the collarbone is on NG101's list of things that make a shoulder problem more likely. In PROSPER, 317 of the 392 women (81 percent) had radiotherapy and 327 (83 percent) had a clearance of the armpit nodes, which is one way of seeing how often these go together.

The part worth acting on is NG101's point about timing. Where a node clearance or that radiotherapy was not planned before the operation but was decided on afterward, the guideline puts you in the higher risk group from then on. So the discharge advice you were given on the ward may have been written for a lower risk than the one you ended up with. Nobody automatically revisits it, which makes it worth raising at your next appointment.

What progress usually looks like

The useful picture comes from PROSPER, which randomized 392 women at 17 UK NHS cancer centers to an exercise program or usual care after non-reconstructive breast cancer surgery (Bruce 2021). At 12 months the exercise group scored better on the DASH questionnaire, which asks about everyday tasks with the arm, shoulder and hand and where a higher score means more difficulty: 16.3 against 23.7, an adjusted difference of about 7.8 points in favor of exercise, with a confidence interval from 3.17 to 12.44. Pain intensity at 12 months was lower in the exercise group too, by about two thirds of a point on a pain rating scale, with an interval from 0.12 to 1.23 points. No increase in complications, lymphedema or adverse events was seen in the exercise group.

Two limits travel with those numbers. PROSPER recruited women at higher risk, with most having had a node clearance and most having had radiotherapy, so it does not show that every woman needs a physiotherapy program. And the benefit at 12 months, while real, is a difference in questionnaire scores rather than a promise about your own arm.

The last movements to come back are usually overhead reaching and reaching behind your back, and a guarded arm often feels tired before it feels sore. That is practice experience rather than a trial finding, so take it as a rough shape and not a timetable. Progress is uneven and a flat week is not a failure. What is not part of normal progress is an arm that keeps swelling, a wound that turns hot or starts leaking, a new lump, or rest pain that climbs week by week. Those are on the warning list for a reason and are not stages to push through.

When to see a physio or your breast care team

Ask for a physiotherapy referral if your arm and shoulder movement has stopped improving or has gone backward, if stiffness or pain is getting in the way of dressing, driving, sleeping or work, or if you are on NG101's higher risk list and nobody has offered you supervised support. NG101 asks for a referral where arm and shoulder mobility stays reduced, so this is a request with a guideline behind it, not a favor.

A few situations belong somewhere other than this page. Shoulder pain that was there before your cancer may be a load-related problem in its own right, and our pages on rotator cuff tendinopathy and shoulder impingement cover those. A genuinely frozen shoulder has its own staged program. If your joints ache in several places at once while you are on endocrine therapy such as an aromatase inhibitor, that is a different problem from a stiff shoulder on the operated side, and joint pain in menopause is the page for it.

Contact your breast care or cancer team, rather than a physio, for anything on the warning list: swelling, a hot or leaking wound, a fever during treatment, a new lump or change in the scar or chest wall, and rest or night pain that keeps getting worse.

You are meant to have that route already. NG101 asks for everyone treated for breast cancer to be given a written care plan that includes the signs and symptoms to look out for and seek advice on, and contact details for immediate referral to specialist care, which is why a new lump or a skin change does not wait for a routine appointment. If nobody gave you those details, ask your breast care nurse for them. Being wrong about one of those costs you a phone call. Being right about it and waiting costs more.

For physiotherapists

NG101's risk stratification is the practical part of this page. The 1.14.14 list plus 1.14.15's post-operative reclassification decides who gets offered supervised support rather than considered for it, and it is worth checking at the first contact, because the decision that changed a patient's risk was often made after the leaflet went home with her.

PROSPER is the trial behind those recommendations and its population matters when the result is applied: 392 women, 17 UK centers, with most having had axillary node clearance and most radiotherapy, program introduced at 7 to 10 days postoperatively with appointments at one and three months. The DASH difference at 12 months was about 7.8 points in favor of exercise (95% CI 3.17 to 12.44). The accompanying Health Technology Assessment monograph reports a cost of roughly 129 pounds per participant, which is the figure to use in a service case.

For timing, the Cochrane review's early versus delayed comparison is the only pooled evidence and its drainage-volume signal in one study is the reason local protocol wins. For load, the PAL trials support progressive resistance training in survivors at risk and in those with stable lymphedema, with supervised initiation, close symptom monitoring and, in the established lymphedema trial, compression during lifting; the established lymphedema trial lifted twice weekly. Campbell 2019 is the dose the stage 3 prescription on this page follows: large muscle groups, 2 to 3 sessions per week, at least 2 sets of 8 to 15 repetitions, start low and progress slow, judged safe in this population when supervised by a fitness professional, with insufficient evidence on whether an unsupervised start is safe. That last clause is the one to read out at a first appointment, because an unsupervised start is what a home program is.

For the swelling side of the assessment, the American Physical Therapy Association oncology section's clinical practice guideline on diagnosing upper quadrant cancer-related lymphedema grades its recommendations by patient presentation (Levenhagen 2017). Two are worth having at a first appointment, each with the grade the guideline itself prints: self-reported swelling, heaviness and numbness should be investigated for early diagnosis, grade B, moderate; and a calculated volume difference between sides of 200 ml or more, or a volume ratio above 1.04 of the affected arm to the other one, helps rule lymphedema in, while a smaller difference cannot rule it out, also grade B. The full text was read for this page, not the abstract, which is why those grade letters are quoted rather than inferred from the wording.

One gap before you go looking. A search for an APTA or Academy of Oncologic Physical Therapy clinical practice guideline specifically on shoulder dysfunction after breast cancer found none, so if you have been told one exists, it was not findable at the time of writing.
