Radiation Oncology

Radiation therapy is one of the most effective ways to treat cancer, and some benign tumors. It works by focusing a beam of ionizing radiation on the cancerous growth or implanting radioactive sources in the cancerous area. It can be used by itself or in combination with other forms of treatment, most often surgery or cancer fighting drugs. To minimize damage to surrounding healthy tissue, only a specific area is treated.

Patient-centered care

Radiation therapy is performed on an outpatient basis, without the need for a hospital stay. The radiation oncologist will determine the number and frequency of treatments, based on your needs. A typical course of treatment is over a one to eight-week period, five days a week. However, many procedures are delivered in just one treatment (also called Stereotactic Radiosurgery) or 2-5 treatments (called Stereotactic Radiation therapy.
