When can you lift your arm fully again after a mastectomy? | CION Cancer Clinics
Most women get back most of their arm movement within a few weeks to a few months of a mastectomy, provided they keep up gentle daily exercises. Recovery is often slower after lymph nodes are removed from the armpit, after radiotherapy or after reconstruction. This page walks through the typical stages, what can hold movement back, which feelings are expected and when to ask for a physiotherapist. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
When will your arm move normally again?
Most women get back most of their arm movement within a few weeks to a few months of a mastectomy, as long as they keep up the exercises. It takes longer if lymph nodes were removed from the armpit, if you have radiotherapy, or if you had reconstruction.
What "normal" usually means
For most people it means lifting the arm straight above the head, reaching behind the back to fasten a blouse, and combing the back of the hair without pain. Heavier tasks, such as lifting a full bucket or a grandchild, usually come back later than reaching. A feeling of tightness across the chest or under the arm can stay for months even when the arm moves fully.
Why there is no single date
The shoulder itself is not operated on. What limits it is soreness in the chest and armpit, the drain, and the scar tightening as it heals. How much tissue was removed, how your skin heals, and how steadily you exercise all change the pace. That is why two women who had the same operation in the same week can be at very different points.
This page describes a typical pattern. Your surgeon or physiotherapist will tell you what to expect after your own operation.The typical pattern
How does movement usually come back, stage by stage?
-
The first days
Hand, wrist and elbow movements, and lifting the arm gently to shoulder height. Most women can feed themselves and brush their teeth with the operated arm, slowly.
-
After the drain comes out
The team usually allows you to take the arm above shoulder height. Wall-climbing with the fingers and hands-behind-the-head stretches start. Expect a pulling feeling along the scar. That is tightness, not damage.
-
The following weeks
Reach improves week by week if you stretch every day. Many women can now dress, cook and do light housework. Reaching behind the back is often the last movement to return.
-
If radiotherapy follows
You need to lie with the arm raised above your head for each session, so good movement is needed before planning. Radiotherapy can tighten the skin and tissue again, and stretching through it and after it matters.
-
The months after
The scar keeps changing for many months. Women who keep stretching tend to hold their movement. Those who stop once they feel better sometimes find stiffness creeping back.
Not sure whether this applies to you?
Ask an oncologistWhy some take longer
What can slow the return of movement?
None of these means the arm will not recover. They mean it may need more time, and sometimes a physiotherapist.
More nodes removed
When many lymph nodes are taken from the armpit, rather than one or two, the area is more sore and swells more. The arm often takes longer to lift fully.
Cording
Some women feel a tight cord, like a guitar string, running from the armpit down the inner arm. It limits reaching. It usually eases with stretching and physiotherapy.
Radiotherapy or reconstruction
Both add tightness to the chest and shoulder. After reconstruction, the surgeon may limit some movements for a while to protect the new shape.
A shoulder that was already stiff
Previous shoulder pain, arthritis or a frozen shoulder can make recovery slower.
Tell the team if you have
- Diabetes
- An old shoulder injury
- Neck or upper back pain
Side by side

Slow, steady gains from week to week
Movement getting worse after it had improved

Commonly believed
What do families believe about using the arm?
"Rest the arm completely until the stitches are out."
Keeping the arm still is the most common reason a shoulder stays stiff. Gentle movement from the day after surgery is what surgeons ask for, within the limits they set.
"If it pulls, something is tearing."
A stretching feeling along the scar is the tissue loosening. Sharp pain, bleeding or a wound that opens is different, and that should be checked.
"She should never do housework with that arm again."
Light daily tasks are part of recovery. Heavy lifting waits until the team agrees, and building up gradually is safer for the arm than avoiding use altogether.
"If the arm is still stiff by now, it will stay that way."
Stiffness can often still improve months later with the right stretches and physiotherapy. It is worth asking for help rather than accepting it.
Being straight with you
When should you ask for a physiotherapist?
Ask if you cannot lift the arm above shoulder height some weeks after the drain has come out, if you feel a tight cord under the arm, or if movement has stopped improving. Earlier help is easier than trying to loosen a shoulder that has been stiff for months.
What a physiotherapist does
They measure how far the arm moves, check the scar and the armpit, and give you a small set of stretches matched to your stage. They may use gentle hands-on work for cording or a tight scar. Most people then carry on at home, with a review visit to check progress.
Why steady effort matters more than hard effort
Short stretches done several times a day loosen the scar better than one long, painful session. Stretch until you feel a pull, hold it while you breathe slowly, then relax. Pushing hard through pain makes the muscles guard and tighten, which sets you back. If a stretch leaves the arm aching into the next day, ease off a little rather than stopping altogether, and mention it at your review.
What this page cannot tell you
It cannot say when your own arm will be back to normal, or whether a stretch is safe for you after reconstruction. Some women never regain quite the reach they had before, especially after extensive node surgery and radiotherapy together. Your surgical team and physiotherapist can tell you what is realistic for you. Even then, most daily tasks can be managed well, and a physiotherapist can suggest easier ways to do the ones that stay hard.
Questions we are asked
Common questions about arm movement after mastectomy
When can I lift my arm above my head?
Usually after the drain has been removed and your team has agreed. Before that, keep lifts to shoulder height. Once cleared, reaching above the head comes back gradually with daily stretches. If it still feels impossible some weeks after the drain is out, ask for a physiotherapy review.
When can I lift heavy things again?
Heavier lifting, such as a full bucket, shopping bags or a child, usually waits longer than reaching. Your surgeon will tell you when. Start with light loads and build up slowly. If the arm or hand swells after lifting, go back a step and mention it at your next visit.
When can I drive?
Only when you can turn the steering wheel quickly, wear a seat belt comfortably and brake hard without pain, and you are no longer taking pain medicines that make you drowsy. Your team will advise you. Riding a two-wheeler needs even more arm strength, so it often waits longer.
Why does my arm feel numb even though it moves?
Small nerves under the arm are often stretched or cut when nodes are removed. That leaves numbness or odd sensations on the inner upper arm. It does not stop the arm moving. Feeling may partly return over months, but some numbness can be permanent.
Will radiotherapy make my arm stiff again?
It can tighten the skin and tissue over the chest and armpit, sometimes for months afterwards. Keeping up your stretches during and after radiotherapy helps a great deal. Tell the radiotherapy team if lifting the arm into position is getting harder.
I am diabetic. Will recovery be slower?
It can be. People with diabetes are more likely to develop a stiff shoulder, and wounds may heal more slowly. Keeping sugar levels steady and starting exercises early both help. Tell your surgeon and physiotherapist about your diabetes so they watch the shoulder closely.
Is it too late to improve after several months?
Usually not. Stiffness and scar tightness can often still improve with a physiotherapist and regular stretching. Progress may be slower than in the early weeks, but it is worth trying. Ask your team for a referral rather than accepting a stiff arm.
How can I help my mother keep up the exercises?
Do the stretches with her at a fixed time each day, perhaps after her bath when the skin is warm. Mark the height her fingers reach on the wall so she can see progress. Take over the heavy chores, but let her do light tasks herself.
