Stereotactic Fractionated Radiotherapy (SFR) uses 7.5 mm pencil-thin X-ray beams to kill brain tumors. Unlike conventional therapy, surgeons using SFR are able to target accurately cancerous cells. The neighboring healthy cells are safe. Thus, SFR has no side-effects like affecting the vision, hearing and mouth of the patient.

Conventional therapy uses wider X-ray beams of 8 cm. They lack accuracy to target at the cancerous cells only. The rays kill healthy cells too. Hence, there may be problems with vision, hearing and mouth.

In SFR, a brain scan is taken to see the tumor. The scan is used to reconstruct a virtual model of the tumor. The surgeon then programs the computer to focus the X-ray beams on the cancerous cells. This computer imaging can even detect hidden tumors. Its high accuracy enables clean sweep of the diseased cells.

With all these advancements in technology, SFR has a higher success rate for treating brain tumors as compared to conventional therapy. It needs 15-20 sessions. The conventional method requires about 35 sessions.

With any type of therapy, there's no guarantee that the tumors will be eliminated forever. Therapy kills the cancerous cells to prevent the contagious spread. However, cancer is known to erupt in multiple organs of a victim. The most dangerous cancer is brain tumor where great accuracy is needed in the treatment. Stereotactic Fractionated Radiotherapy is the latest ray of hope for brain tumor patients.
