How are gamma rays used for cancer treatment?
Radiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells.

How does radiation help cancer?
When radiation is combined with surgery, it can be given: 1 Before surgery, to shrink the size of the cancer so it can be removed by surgery and be less likely to return. 2 During surgery, so that it goes straight to the cancer without passing through the skin. Radiation therapy used this way is called intraoperative radiation. With this technique, doctors can more easily protect nearby normal tissues from radiation. 3 After surgery to kill any cancer cells that remain.

Gamma rays, X-rays and charged particles are types of radiations used for cancer treatment. These radiations are equally harmful to normal cells, they cannot distinguish between normal and cancerous cells and therefore come with side effects along with the treatment of cancer.
Why are X-rays used for cancer?
X-rays are more often used to treat cancer than gamma rays because x-rays are much easier to control and focus. The tactic for effective treatment of cancer is to expose the tumor to a deadly high dose of radiation without too much damage to the surrounding tissues.
What is radiation therapy?
Continue Reading. Radiation therapy (also called radiotherapy) is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors. At high doses, radiation therapy kills cancer cells or slows their growth by damaging their DNA (DNA breaks).
Which cells are more sensitive to radiation?
Normal cells which divide quickly are also more sensitive to radiation. Cells which line the gastrointestinal tract and blood forming cells divide frequently and so they are more sensitive to exposure to radiation. Cells which don't divide often are more resistant to radiation, like nerve cells and the brain.

Can gamma rays cause cancer?
Gamma rays are not known to be that nice to cause harm only to cancerous cells. In a normal body, these rays can ionize living tissue, causing cancer by producing free radicals.
