Why is high energy radiation effective?

Radiation is most effective at killing cells that are actively dividing. Cancer cells are more vulnerable to radiation for two reasons: they divide more rapidly than normal cells. they do not repair this damage as effectively as normal cells.

What type of radiation is used for cancer?

Radiation therapy uses high-energy radiation to shrink tumors and kill cancer cells (1). X-rays, gamma rays, and charged particles are types of radiation used for cancer treatment.

How long does it take radiation to shrink a tumor?

Is gamma rays used to treat cancer?

You may also hear it called radiotherapy or therapeutic radiology. Radiation therapy kills cancer cells with beams of high-energy X-rays, gamma rays, or charged particles (called electrons or protons). It can be used in many ways. It depends on the type of cancer you have and where it is in your body.
