U.S. Senator John McCain diagnosed with brain cancer

Senator John McCainhas been diagnosed with brain cancer, the Mayo Clinic Hospital in Phoenix said in a release.

The tumor was discovered after the senior Arizona senator underwent a minor procedure last week to remove a blood clot from above his left eye.

“Subsequent tissue pathology revealed that a primary brain tumor known as a glioblastoma was associated with the blood clot,” the hospital said in a statement.

McCain’s latest diagnosis is not his first battle with cancer.He underwent a procedure in 2000 to remove a type of skin cancer called melanoma from the left side of his face.

McCain also had a melanoma removed from his left arm in 2000 and another removed from his nose in 2002. Both were determined to be the least dangerous types of melanoma.

McCain’s office said in a statement that the Arizona Republican remained in good spirits  and is confident that any treatments will be effective.

“He is in good spirits as he continues to recover at home with his family in Arizona,” his office said.
