Radiation Oncology

Radiation oncology, also called radiation therapy, uses radiation to kill cancer cells. Used by itself or with cancer-fighting medicines or surgery, radiation is one of the most effective cancer treatments. Radiation can help shrink a tumor to be removed more easily in surgery or help destroy any remaining cancer cells after surgery. In some cases, radiation without surgery may be the most appropriate treatment for certain types of cancer.

The goal of radiation treatment is to target specific tumors with the exact amount of radiation required while minimizing exposure to surrounding normal, healthy tissue.

Most patients who receive radiation therapy at the Helen F. Graham Cancer Center & Research Institute will receive external-beam radiation treatments from one of our linear accelerators. These highly accurate machines beam radiation into the tumor from outside your body. You will not feel the radiation pass through your skin.

The actual treatment takes only two to three minutes. Using the latest treatment and planning technologies, we can target your cancer with pinpoint accuracy and reduce the length of time you need to spend receiving treatments.

Your doctor will prescribe a detailed, individualized treatment plan specific to your needs. Your course of therapy will be based on precise measurements gathered from a physical examination and diagnostic imaging, such as computer tomography (CT scan) or magnetic resonance imaging (MRI). The Helen F. Graham Cancer Center has image-guided radiation therapy, which allows your doctor to track the location and movement of the tumor while you are on the treatment table.
