Ur my buddy , i have PCOS and also had brain tumor (very similar to yours but on my hearing nerve,yeah a big one which had to be taken out 2 times in 2 years)...the one i had happens 1 in 1lac :( and i was the choosen one.
I donno which method surgery your neurosurgeon will suggest but whatever be it i heard and experienced that its a fast recovery.My first surgery (thru skull & the nerve had to be chopped off so i am deaf in my left ear wth left facial weakness) was for 11 hrs and still they could not take the whole out later after 2 yrs I had 6 hrs surgery and all out.
Funny that i had no headache or hearing loss as symptoms which are usually very common. mood swings always :))
anyways hang in there, just be determined to get rid of it once for all(the reason i refused radiotherapy). trust me u will recover very fast which still amazes me.
