| Radiation therapy (or radiotherapy) techniques have steadily improved over several decades. Treatments now target the cancers more precisely, and more is known about selecting radiation doses. However, oncologists prescribe radiation therapy only when its benefits (improved survival rate and relief of symptoms) outweigh the risk of this and other complications. There may also be permanent darkening or "bronzing" of the skin in the treated area. When the chest and neck are treated, patients may have a dry, sore throat and some trouble swallowing. Radiation therapy to the abdomen may cause nausea, vomiting, diarrhea, or urinary discomfort. If necessary, treatment may have to be postponed to let the blood counts return to normal. It may also help to know that, in most cases, side-effects are not permanent. |
