He was a US Navy pilot, shot down over Vietnam and held for over five years as a prisoner of war. McCain has a reputation for being a tough, independent-minded maverick of a senator and a senior authority in national security issues. He has forcefully argued in favor of US' military might.
McCain's doctors said tissue analysis revealed that he's suffering from glioblastoma, a particularly aggressive brain tumour. The tumour's frequency increases with age and affects more men than women.
