Radiosensitizers & Radioprotectors:

Radio sensitizers and radio protectors are chemicals that modify a cell's response to radiation. Radio sensitizers are drugs that make cancer cells more sensitive to the effects of radiation therapy.

Some anticancer drugs, such as 5-fluorouracil and cisplatin are effective in making the cancer cells more sensitive to radiation therapy. Radio protectors are drugs that protect normal (noncancerous) cells from the damage caused by radiation therapy. These agents promote the repair of normal cells that are exposed to radiation. E.g. amifostine is the only drug approved by the FDA as a radio protector.

There is opinion saying Radiotherapy and Chemotherapy treatment are not actually killing the cancer cells but the cells are kept [or maybe deactivated] for a period of time... It will strike back. At that point of time, we may be able to do the same treatment/s, but the attack usually more severe than the first. Possibly, the patient may have no energy to go through the second episode of treatment (due to age and/or tiredness and/or cost incurred). If you are not lucky, the second cancer will strike due to the treatment itself. So, instead of killing the cancer cells the treatment may create second cancer. Appreciate comments please
