I had a 1.5 centimeter pineal tumor removed a week ago. my question is why does a lot of neurosurgeons at great university hospitals not help me?

Please see below.: Getting to the pineal region surgically can be very challenging and often risky. Sometimes it can be done minimally invasively via endoscopic techniques. This would explain why many neurosurgeons were reluctant to operate. If you had this surgery a week ago and you're good enough neurologically to be typing questions online you're doing great.

Few had experience : Not a day to day disease is uncommon , I am glad you are ok , before the minimally invasive endoscopic surgery , reaching the pineal gland in complex location with out injuring normal brain tissue is a big problem, also remarkable progress has been made in neurosurgery, skills, training, equipment , concepts and besides you had a great neuro-surgeon and thank him, good luck.
