The intensity of the AN contrast on the MRI is often decreased as well, indicating the death of the tumor cells. It is like a plugged up feeling.

No large bandages are needed. Given the low complication rates of GK, the biggest drawback for most patients is their fear of possible malignancy. Yet, there has been no connection between GK and cancer reported in all that time. That is to say, the overall rate of brain cancer in AN patients who have been treated by GK has not been any higher than for post-surgery patients. The order in which the procedure is carried out is standard, but the number of shots, the collimator size, and the dose all vary from case to case.
