Exercise and radiotherapy
It is a misconception that exercise should be avoided during radiotherapy. Its true your ability to perform strenuous exercise will be impaired but light exercise should be encouraged. There are several good reasons why light exercise is often helpful.
Cancer and certainly its therapies often cause fatigue. Light and stimulating exercise can help to reduce this. This has to carefully balanced. Although plenty of rest is important, between these times it is better to be active. For example a sleep after lunch may be required but then it would be useful to put on a pair of training shoes and go for walk in the open - preferably in pleasant stimulating surroundings such as a park or riverbank. Although this seems a great effort at first, patients often find their overall levels of fatigue are reduced. (also see living with fatigue)
Cancer can increase the risk of thrombosis - particularly if there is any disease in the pelvis or lower abdomen. On top of this if patients are less active this further increases the risk. Regular exercise cause the blood to be pumped through the veins and reduce the risk of it stagnating and clotting in the veins.
Nausea can be a problem with some radiotherapy therapies. If it is mild sometimes an walk or gentle run can do wonders.
Radiotherapy can cause thickening on the skin and underlying tissues. Exercise especially if associated with stretching can reduce this underlying thickening.
Exercise improves your mood by releasing endorphines into the blood stream. This may also prevent the onset of depression.
