Radiation therapy is an important part of cancer treatment but it comes with its own side effects as you mentioned. It destroys both cancerous as well as healthy cells ,it is due to this stem cell therapy is given to the patient. Stem cells have the capacity to form different cell types. Stem cell therapy includes bone marrow transplantation
Radiation is a cause of cancer as well as it can cure cancer. it all depends on amount, time of exposure of radiation. for example in case of madam curie she got bone cancer because of her research where she had to spend a lot of time being exposed to radiation. The thing that you mentioned about chemotherapy is right. In chemotherapy the cells which are cancerous are destroyed. cell division is common process going in our body, but problem with cancer cell is that they divide quite exponentially. there are some cells in our body like hair which divide rapidly but not all normal cells divide as rapidly as hair. When we do chemotherapy we kill those rapidly multiplying cancerous cells. As a result hair are lost after chemotherapy.

Cancer is basically a deficiency of Vitamin B17 (controversy on whether it can be called a vitamin) because of which the cells start behaving abnormally. In the initial stages it can be treated by intake of apple seeds, plum seeds, apricots or other sources of B17 over time. In the later stages this may not be enough.
