If you know you are going to have treatment, your doctor might encourage you to start some physical activity beforehand. This is to help improve your general fitness level. It can also help with your recovery after treatment.
Being active before treatment starts may mean you have fewer side effects, or that they are less severe. It can also help you feel more in control and mentally prepared for treatment. It may help you recover more quickly.
Some people have to start treatment straight away, so there is no time to become more active before treatment. If this happens, you can talk to your cancer doctor or specialist nurse about plans to get active during or after treatment. They may refer you to a physiotherapist for advice.
