Verdict:

I have a brain tumor found in less than 1% of people with pituitary brain tumors. In other words, it's incredibly rare. There are approximately only 200 cases of this in the world. Last time the doctor saw a case somewhat similar to mine was, in his words "many, many years ago".

In a couple of weeks, the team of doctors want to begin a two step treatment:
1) Radiation Therapy using Gamma Knife (all the dosage of conventional radiation in a one-time, massive blast)
2) Chemotherapy to begin immediately afterwards
