How it works.

Radiation work by using high-energy radiation to kill the cancer cells by damaging their DNA. One problem with radiation therapy is that it kills normal cells along with cancer cells, therefor treatment must be carefully planed to have min. side effects.


About half of all cancer patients use radiation. Some use it with surgery or chemotherapy or both. Radiation is sometimes abbreviated as XRT or DXT.

What are the side effects?

fatigue, skin change- dryness, itching, peeling, ect. occurs because radiation damages healthy skin cells.

Depending on where being treated- Diarrhea, hair loss, mouth problems, nausea and vomiting, sexual changing, swelling, trouble swallowing.

How is it given to the patient?

Radiation can come from a machine outside the body or from radioactive material placed in the body near cancer cells. Systemic radiation therapy uses a radioactive substance, given by mouth or into a vein, that travels in the blood to tissues throughout the body.
