Stereotactic Radiosurgery (SRS)
Stereotactic Radiosurgery (SRS) is a noninvasive radiotherapy treatment technique that delivers very small and highly concentrated radiation beams to target tumors. It is referred to as “surgery” because the very high dose delivered in an accelerated course to the target minimally impacts surrounding structures and has the ability to result in faster shrinking of the tumor size. For sensitive parts of the body, such as the brain and the spine, SRS treatments are usually completed in one single fraction and accompanied by the presence and participation of a neurologist. When radiosurgery is delivered to other less sensitive part of the body, such as the lung or the prostate, it is sometimes referred to as Stereotactic Body Radiotherapy (SBRT) or fractionated stereotactic radiotherapy, and the prescribed dose is delivered in 5 fractions or less. At consultation the Radiation Oncologist will discuss your candidacy for stereotactic radiotherapy treatments, as well as preparations and expectations for treatment.
