Who We Are

Radiation Oncology is the medical field that specializes in treating cancer patients with radiation therapy. Radiation can be given as a curative treatment alone in some cases, or in combination with surgery and/or chemotherapy. Radiation also can be used palliatively, i.e. to help control symptoms such as pain or to prevent fracture of bones involved with cancer. In certain specializes cases, radiation therapy is used for non-cancer treatment. These include arterio-venous malformations, trigeminal neuralgia, essential tremor, and treating other benign tumors.

We as radiation oncologists work as part of a multi-disciplinary team alongside medical oncologists (who deliver chemotherapy and hormonal therapy), surgeons, and other care providers. Overall, about 60% of all cancer patients in the U.S. will receive radiation as part of their cancer treatment.
