| | Definition: | | Radiation therapy is a form of treatment for cancer or abnormal growth by irradiating the target with radioactive material which can be gamma rays, electrons, alpha particles, and positrons. Common side effects are: patients usually feel very tired during treatment. The radiated tissue looses texture, becomes red (erythematous) , hard and itchy (desquamated) ; towards the end, it can be moist and weepy. Ulceration and necrosis may be seen. Some organs in the field of radiation may be affected, e.g. pulmonary fibrosis from the treatment of breast cancer, radiation enteritis from radiation for intra-abdominal malignancies. |
