Radiation therapy does cause great damage to cancer cells, but it also has some effect on surrounding normal cells. If radiation is above the decided levels for that organ damage can be delivered to normal cells making them weak. The radiated normal cells will still remain slightly effected even after several years, and therefore repeat radiation treatment in the same area is not performed. However, depending on the type of cancer, there are cases where it can be performed safely again in the same area, where the first time irradiation quantity was small and it was a first time therapy.
