      Its excellent and few side effects..But of course its dependent upon how many lesions. however, the number is not an issue its the size of each one that can be an issue.

      need2kno,
      Hello, I am an oncology nurse and Cas1 is correct in that it is excellent therapy. Gamma Knife and Cyber Knife are SRS or StereoTactic RadioSurgery. A perfect candidate for SRS would be a tumor that is spherical or ball-like, 2.5 cm or less in size (one Inch), not touching a vital nerve/sensitive nerve (optic or hearing nerve). It is much more intense than fractionated radiation so there is a higher risk involved. Fractionated has a lower risk but it is more time consuming. With Gamma Knife, size does matter, Cas is right. a 4.4cm is too long for a Gamma knife. Gamma is not used on any lesion touching a nerve, or on a tumor wrapped around any vascular structures. I hope this helps answer your question, Carm RN.
