Brain Tumor?!?

When we got back from our oceanside/la trip my grandma called and said that my grandpa was having some double vision and headaches. He went to the eye doctor that ruled out it being a vision or eye problem and referred them to a neurologist. After running some blood work and doing an MRI they found a tumor on his pituitary gland behind his optic nerve and determined that surgery was needed. Within two weeks of that he was on the operating table. It's always a scary time when a loved one is sick or needs surgery but I knew that God's will would be done and trusted in Him and was able to rest in that. And Praise God, the surgery went well and he was home in two days. They were able to get 90% of the tumor and at first they had talked about doing radiation to get the rest of it out but now it sounds like they want to possibly try using a cyber knife but he'll know more the end of July.
