The most common side effect of radiation therapy is fatigue, and it is usually not severe.  Many patients are able to continue their normal routines and daily activities.  However, as treating cancer requires considerable mental and physical effort, rest and relaxation is recommended whenever possible.

Any additional side effects are usually mild and may develop around the second or third week of treatment.  For example, some patients may eventually develop skin irritation resembling mild to moderate sunburn around the area being treated.

Your radiation oncologist and oncology nurse will discuss with you the potential side effects of your treatments and advise you on how to manage them.
