Radiosurgery can be the treatment of choice for certain cancers. Stereotactic radiosurgery (SRS) delivers high doses of radiation to treat tumors with great precision. SRS is a technique that is most commonly used for tumors or other medical conditions in the brain or central nervous system (CNS). With SRS, clinicians can focus the radiation dose to the outline of the tumor and minimize dose to the surrounding healthy tissue. SRS treatments use high precision, accuracy, and sophisticated 3-D imaging to deliver a concentrated dose of radiation in a single treatment. In some cases fractionated stereotactic radiosurgery is used. This is a process in which the total dose of stereotactic radiation is divided into several smaller doses of radiation on separate days of treatment ranging from two to five treatments.
