About Radiation Therapy

Radiation therapy is a highly effective treatment for shrinking tumors and killing cancer cells. It works by damaging the DNA of the cancer cells, so that they can no longer divide or die. Depending on the specifics of your case, your radiation therapy might also be combined with other modes of treatment, such as surgery or chemotherapy. Radiation therapy can be received before, during of after surgery, depending on the type of cancer being treated.

Types Of Radiation Therapy

External-Beam Radiation Therapy: This is the most widely used type of radiation therapy. It delivers radiation directly to the tumor from outside of the body, most often by machines called linear accelerators or “linacs”. The machines move all around you, without touching you. The radiation cannot be seen, felt or smelled. Treatments are generally received daily, five days per week, over the course of several weeks in an outpatient setting, so you don’t have to stay in the hospital. Learn more about the treatments we offer.

Internal Radiation Therapy: Also called brachytherapy, internal radiation therapy involves placing radioactive material on or inside your body near the tumor cells. Brachytherapy can be given as a low-dose-rate (LDR) or a high-dose-rate (HDR) treatment. The placement of the radiation source may be temporary or permanent.
