I had three operations to remove my brain tumor, yet the tumor returned. I lost my vision due to the tumor. It was restored with 28 days of cyber knife radiation, on an egg yoke size tumor. Then my surgeon had to remove the dead tumor that rested on the optic nerve. Tumor is gone, thank GOD! My Humatologist doctor has me on 15 MGS of Hydrocortisone, two every morning, one each evening. Doctor says, I'll need to keep taking Hydrocortison for the rest of my life. With the side effects of this drug I'm afraid to continue taking this drug, any help with this question.please reply.
