Politics: John McCain has brain cancer, is expected to undergo treatment

McCain and his family are reviewing treatment options, which could include a combination of chemotherapy and radiation.

Sen. John McCain has been diagnosed with brain cancer, the Arizona lawmaker's office announced on Wednesday.

"On Friday, July 14, Sen. John McCain underwent a procedure to remove a blood clot from above his left eye at Mayo Clinic Hospital in Phoenix. Subsequent tissue pathology revealed that a primary brain tumor known as a glioblastoma was associated with the blood clot," the statement read.

McCain and his family are reviewing treatment options, which could include a combination of chemotherapy and radiation.

Before the tumor was discovered, the senator's office had suggested the blood-clot procedure might keep the senator off the job for a week, but the cancer diagnosis and forthcoming treatment could sideline McCain indefinitely.

The American Brain Tumor Association notes that Glioblastomas are "usually highly malignant," and that "the cells reproduce quickly and they are supported by a large network of blood vessels."

McCain's office said the senator was recovering his blood-clot surgery "amazingly well." His doctors said the senator's underlying health is "excellent."
