My father is currently in the ICU at the Minnesota clinic. He was diagnosed with a pituitary tumor 10 years ago. Back then my dad was only the 3rd person in US medical history to have this particular tumor. He received Gama-Knife radiation surgery 10 years ago at Mayo to shrink the tumor as physical entry was “certain death”. The tumor grew back and doubled in size and is now pressing against his optic nerves and brain stem. His prognosis is 6 months. I am wondering if anyone since my father has ever been diagnosed with this particular type of brain tumor, or is my dad still only #3?
