When treatment is started early, radiation therapy can be very effective in stopping cancer. Following surgery, radiation therapy can destroy any remaining cancer cells around the site of the tumor that surgery could not remove.

Radiation therapy can retain the organ that has cancer cells on it because it can just radiate that specific organ to destroy the cancer cells and when the cells are dead the organ can function normally rather than having surgery which remove the organ but not having full security that the cancer cells are dead.
Radiotherapy have side effects but most of them are temporary. Fatigue is the most common side effect of radiotherapy , you can feel more tired than usual but it is not a major problem. There are ways to lessen tiredness while undergoing radiotherapy, have enough sleep, take a nap during the day , try not to use lot of energy are examples of it.
