It can be scary and overwhelming when you hear you have a TUMOR! I would ensure I was lined up with an endocrinologist who treats tumors, not one who specializes in diabetes. I would get a good neurosurgeon if surgery was going to be recommended. I would recommend taking a deep breath, relax and do some research on line. A good place to start is Pituitary.org. Learn everything you can. Ask lots of questions and don't be afraid to question your doctor or ask for a second opinion if you don't agree. Doctors are not gods, and not all have answers. Know yourself as you are your own best advocate.
