    The most common side effects of radiation therapy are temporary skin irritation and temporary fatigue. Radiation to the throat can cause soreness in the mouth. Radiation to the chest can cause discomfort in swallowing. Radiation to the abdomen can cause nausea. Radiation therapy to the pelvis can cause diarrhea. There are less common and rare side effects of radiation therapy.

    After effects from radiation therapy may occur because of permanent damage to normal cells or to structures of the body that are either right in or close to the area exposed to radiation (the field or radiation port).

    Radiation treatment is administered to a specific place in the body. after effects occur only in the area of the body that was exposed to the radiation (known as local effects).

    In some cases, X-rays in the intended field may scatter and expose surrounding tissues and organs to small doses of radiation. Depending on the position of a tumor, it could also be necessary to include healthy tissue and organs in the field in order to ensure complete treatment of the cancer.
