Radiation Oncology Centers of Excellence

The Department of Radiation Oncology offers a broad range of radiation oncology services either on site or by referral.
Radiation therapy is a form of treatment that utilize high energy linear accelerator with external beam low and high energy x-rays and electrons, in addition to interstitial and intracavitary therapy, including prostate implants to treat cancer. Radiosurgery with the use of intensity modulated radiation therapy allows intensive radiation to be delivered to brain tumors, as well as other parts of the body to obtain best outcomes.

Services are coordinated with chemotherapy and surgery, and are performed by an expert staff of physicians, physicists, radiation technologists and nurses. The department has a multimodality approach to the patient's treatment, cooperating in management with the referring physicians and other oncologists involved in the patient's treatment to assure integrated care. Referring physicians receive regular reports indicating the proposed treatment and the results achieved during and after the course of treatment. Comprehensive nursing care, including nutrition and social work services, is a significant part of every patient's care. All physicians are board certified.
