Radiation Oncology Program

In This Section


Radiation oncology, also known as radiation therapy, is the use of high-energy rays to kill damage cancer cells and stop them from growing and dividing. Like surgery, radiation oncology is essentially a local treatment; it affects cancer cells only in the treated area.

Radiation can come from a machine (external radiation). It can also come from an implant (a small container of radioactive material) placed directly into or near the tumor (internal radiation). Some patients receive both kinds of radiation therapy.

Using a multidisciplinary team approach, the Radiation Therapy team works closely with our colleagues in oncology, surgery, and other departments to develop the best plan-of-care for cancer patients. Radiation Therapy at Roger Williams Medical Center is provided in partnership with 21st Century Oncology, a leading developer of radiation therapy centers around the country.
