I was diagnosed in 2011 after a severe vertigo attack which I've been told is unrelated. I have a nonfunctioning macroadenoma. I'm being treated at Columbia Presbyterian in nyc. My endocrinologist thinks it should come out since it is growing, was 1.5 cm when they found it and is currently 1.6 cm, I'm healthy enough for surgery, going to be 50 in October, and there is a small chance it could bleed. After reading posts, I'm scared about the post surgery. For those of you who have had this done, what would you do differently? Should I get a second opinion? I'm part of a research study at Columbia that had over 200 people with the same type of tumor- I'm sure they treat a lot with other pituitary tumors as well.
