Radiotherapy can cause tiredness. Other side effects depend on the part of the body being treated. When radiotherapy is given to relieve symptoms, the side effects are usually mild. The doctor who plans your radiotherapy (clinical oncologist) or a specialist nurse will tell you what to expect. Usually side effects go away slowly when your course of treatment has finished. You should let your doctor know if they continue.
