Stereotactic Radiosurgery
Stereotactic body radiation therapy

Traditional forms of Radiation therapy expose large areas of normal tissue to unnecessary Radiation. This leads to unacceptable side effects, especially in critical areas like brain and lung. Sterotactic Radiosurgery (SRS) and Stereotactic Body Radiation Therapy (SBRT) are advanced and modernized forms of radiation therapy which help to deliver high dose radiation to a small focused area thereby minimizing effect on nearby organs and reducing treatment related side effects. Stereotactic Radiosurgery (SRS) and Stereotactic Body Radiation Therapy (SBRT) are important alternatives to invasive surgery, especially for patients who are unable to undergo surgery and for tumors and abnormalities that are hard to reach and located close to vital organs.SRS and SBRT are very similar, but SRS delivers a large dose of radiation on a single day and SBRT has a fractionated treatment schedule. SRS is used to treat many types of brain tumors, arteriovenous malformations (AVMs) and functional disorders, where as SBRT is used to treat malignant small-to-medium size tumors in the body including lung, liver, spine and prostate etc. One more benefit of these treatments over conventional radiation treatment is that the treatment durations are much shorter. Whereas two-year success rates for conventional treatment range from 30 to 40 percent, the success rates for SBRT range from 80 to 90 percent in some of the tumors.
