My cousin brother has frequent headaches, today he got a MRI scan, it disclosed some 1 inch stone type formation in the brain, I don t exactly know what it is, he called up on phone and told me. I just wanted to know is it a brain cancer or a brain tumor? How can it be treated? The doctors suggested to undergo a operation where he did a MRI scan. How much would a operation cost? Can it be treated witout a operation? please advice..
