Hi Ingy,
Sorry about the news, I understand exactly how you feel. But do know you have several options ...depending on where in your sinuses it is, it sounds as if a biospy is available through traditional means....no touching the brain...You tumor is in a similar spot to mine but if it is an AN, then it would be a little to the left,,,better actually. There are several surgical options available, as well as CK and GK....I would definatly find out what you can about fractionated therapy as it is most likely the best option for preserving those nerves...
If it is not causing you too much current trouble, those are the least invasive treatments and have good results....
Removing them is also an option....but know you have lots of time...they are usually very slow growing, so although April seems like a really long way off, if your Dr diagnosed you with an AN, they are pretty recognizable and they are a type of schwanomma tumor...which would explain the continued growth into your sinus cavity..relatively common, believe it or not. SO hang in there, you are not alone, read what you can, and find a Dr. you are comfortable with..that is the most key thing...there are lots of treatments available and you have to choose which is right for you.....
