Q. When will I see the effects of Gamma Knife treatment?
The Gamma Knife is a safe and effective procedure that may show its benefits over several days to several years, depending on the type of medical condition that is being treated. The radiation changes the DNA in the tumor cells or lesions and the cells are no longer able to reproduce, eventually making the lesion static.
Certain abnormalities gradually dissolve and ultimately disappear. Some may simply exhibit no further growth. The effectiveness of the Gamma Knife radiosurgery is monitored using MRI scans at regular intervals. The goal of the procedure is to tumor control, defined as stable tumor size or shrinkage. In case of vascular malformations, the control is generally considered to be the total obliteration.
