I was diagnosed in 2020. My tumor was only 1.75 cm. Its location is in the olfactory groove. I’ve been on a watch and wait to determine the growth rate which is 1 mm a year. It’s now at 2 cm and needs to come out because it’s edging closer to the optic nerve. I’ve interviewed 7 surgeons and they all have a different opinion as to the manner they want to take it out. Deciding when and who will perform the surgery has me very stressed right now. I’m 63 and not getting any younger. My advice is to do your research and find the best surgeon you feel comfortable with now because eventually, it will need to come out. Hugs!!
