Tissue damage after radiation therapy

It is a rare symptom, and since the body does not completely forget the radiation therapy given, There is a certain limit that if the treated organ exceeds it, this organ may be damaged. Damage rates are higher when radiation therapy is given more than once to the same site. For example, if brain tumors return in the same place and surgery is not an option, the treatment team is forced to give radiation therapy, even though everyone knows that the rate of damage is higher than usual, but the risk of the tumor is greater than the potential damage due to the treatment.
