American Senator McCain is very ill, this is a diagnosis.

The American Senator, John McCain, has been diagnosed with brain cancer and has begun treatment.

The 80-year-old politician discovered that he had cancer last week during an operation, where he had gone to remove a blood mass numbed above the left eye.

The six-year senator and republican presidential candidate in 2008 underwent surgery at a clinic in Phoenix, in the state of Arizona, last Friday. The analysis revealed that a primary brain tumor known as glioblastoma was related to blood clotting. However, doctors say he is strong and is currently in good health, hoping that radiation treatment will eliminate the disease. We remember that the Vietnam veteran spent more than five years as a prisoner of war.
