Gamma Knife Radiosurgery - A Revolutionary Modality in the Treatment of Brain Tumors

Abstract

For delivering highly accurate radiation therapy with pin-point accuracy to brain tumors, radiosurgery employing Gamma Knife Radiosurgery technique is a revolutionary new armamentarium that enables delivering focused intense beam of gamma rays to brain lesions. Neither employing an actual knife nor surgery, it is called “surgery” because the results are as good, even better, than actual surgeries. Gamma Knife radiosurgery can be as effective in treating nerve conditions and blood vessel malformations as brain tumors [1] (Table 1). The tumor gradually shrinks after treatment that damages and destroys the tumor cell DNA that cannot grow or reproduce anymore.
