Physical activity has a number of benefits for people with breast cancer. But you might need to consider a few things if you’ve just had, or are still having, treatment.
Before starting any type of activity, talk to your treatment team or GP.
1. Exercise after surgery
How soon you start, what type and how much physical activity you do after surgery will depend on the type of surgery you’ve had, your recovery and your fitness level before your surgery.
Many people feel well enough to go for a short walk a few days after surgery, but others need longer to rest. Build your physical activity levels up gradually, and remember it may take time to return to the level of activity you were doing before your surgery.
After surgery for breast cancer, shoulder and arm exercises are important to help you regain the movement and function you had before surgery.
You may be advised not to lift or push with your arm on the side of your surgery and not to lift anything heavy. Your breast care nurse or a physiotherapist will tell you more about this.
If you’ve had any type of breast reconstruction, ask your surgeon, breast care nurse or a physiotherapist which exercises they recommend. The types of activities you can do may be limited for some time, depending on the type of reconstruction you’ve had.
2. Exercise during and after chemotherapy
Swimming and chemotherapy

If you would like to go swimming during or soon after chemotherapy, discuss it with your treatment team first.
Other activities
Chemotherapy affects people in different ways. Some people have very few side effects and are able to continue with their usual activities.
Others feel extremely tired or unwell and unable to carry on as usual. This can be frustrating if you want to be physically active.

Talk to your treatment team about any activities you would like to do while you’re having treatment. They can tell you which activities are suitable.
3. Exercise during and after radiotherapy
Swimming and radiotherapy
You may be advised to avoid swimming during and shortly afterwards. This is because radiotherapy can cause skin changes and these can be irritated by chlorine or chemicals in the pool. Also swimwear can rub the skin and cause discomfort.
However, if you don’t have any skin problems, it’s possible to continue swimming but check with your treatment team first. They may recommend that you rinse the treated area after swimming to remove any chlorine.
Other activities
If you’re having radiotherapy you may be advised to continue with your shoulder and arm exercises.
You could also do any other gentle exercise that feels comfortable, such as walking, gentle stretching, yoga and pilates. There’s no reason not to exercise during radiotherapy if you feel up to it.
4. Exercise while taking hormone (endocrine) therapy
