What is Radiation Therapy?

Radiation therapy (also called radiotherapy) is a cancer treatment that uses high doses of radiation to kill cancer cells


How Radiation Therapy Works Against Cancer

At high doses, radiation therapy kills cancer cells by damaging their DNA. This DNA damage leads to killing of such damaged cells throught thr body's normal mechanisms that leads to shrinkage of tumor.

There are two main types of radiation therapy, external beam and internal.

External Beam Radiation Therapy

External beam radiation therapy comes from a machine that aims radiation at your cancer, sending radiation to a part of your body from many directions. External beam radiation therapy is a local treatment, which means it treats a specific part of your body. For example, if you have cancer in your breast, you will have radiation only to your breast.

Internal Radiation Therapy

Internal radiation therapy is a treatment in which a source of radiation is put inside the body. Brachytherapy is a type of internal radiation therapy in which a solid radiation source is placed in the body, in or near the tumor that gives off radiation for some time. Like external beam radiation therapy, brachytherapy is a local treatment is directyed only to a specific part of the body.
