Radiation Oncology - Dignity Health - St. Mary Medical Center

Radiation oncology is a type of cancer treatment that uses high-energy beams (similar to X-rays) to target and destroy cancer cells.

A radiation oncologist is a doctor who specializes in this kind of care. They create a personalized treatment plan designed to treat the cancer while protecting as much healthy tissue as possible.

Radiation therapy may be used on its own or along with other treatments like surgery or chemotherapy. It can help shrink tumors, kill remaining cancer cells and reduce the risk of cancer coming back. Modern technology makes radiation therapy very precise, helping improve results while limiting side effects.

Our radiation oncology department at St. Mary Medical Center offers advanced treatment options for various cancers, such as brain, breast, lung, prostate, head and neck, and gastrointestinal cancers, while minimizing damage to healthy tissues. These radiation therapies include:

• Image guided radiation therapy (IGRT)

• Brachytherapy (High Dose Radiation)

• 3D conventional radiotherapy

• Intensity-modulated radiation therapy (IMRT)

• Volumetric modulated arc therapy (VMAT)

We use advanced, precise radiation therapy to treat many types of cancer, including breast, lung, prostate, brain and more. Our personalized approach targets cancer cells while protecting healthy tissue, offering faster, more comfortable and safer treatments.
