Full dose of radiation is usually carried out only once on one area of the body. Healthy tissues can easily tolerate small doses of irradiation. Radiologist, who conducts a course of radiotherapy, he knows how to pick up the required dose of radiation to: achieve maximum therapeutic outcome and to avoid or minimize adverse effects of radiation.
After a course of radiation therapy is over, healthy tissue to heal and become normal. But as your normal tissue cells have already received a dose of radiation, they were able to move, repeated exposure to a full dose of radiation possible. Therefore, if in the same area there is a relapse of the tumor, may or may not be repeated radiation therapy depends on the dose that the patient has already received.
It is important to understand that all this relates to the conduct of radiation therapy to the same area, when you need it re-exposure to radiation. If in any situation requires radiation therapy in a different area, for example, about metastasis, the exposure can be carried out in the full dose.
