At the request of McCain and his family, the Mayo Clinic released a statement about the Arizona senator 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 Pheonix,” the statement read.

“Subsequent tissue pathology revealed that a primary brain tumour known as a glioblastoma was associated with the blood clot.”

McCain’s brain tumour is the same kind of cancer Tragically Hip frontman Gord Downie has been diagnosed with.

Experts say Downie, 53, is battling an incurable cancer that’s also among the most common and most aggressive brain tumours.

Downie’s cancer is a primary brain tumour, meaning it started from within the brain itself and didn’t spread from another part of the body.

Downie underwent surgery to remove a “bulk” of his tumour on the left temporal lobe of the brain. He took on radiation treatment for six weeks paired with chemotherapy.

Other celebrities have encountered glioblastoma, Perry noted, including Joe Biden’s son and Ted Kennedy.

What makes glioblastoma incurable is that it’s “rapidly growing,” according to Dr. Sunit Das, a surgical neurologist at St. Michael’s Hospital in Toronto. He hasn’t treated Downie but works with glioblastoma patients regularly.

Unlike lung cancer which is tied to smoking or colon cancer which has links to eating too much processed meat, for example, it’s unclear what triggers glioblastoma.

Two to three people per 100,000 encounter the disease in Canada, the United States and Europe. It’s more common in older individuals and in men more than women.

Common symptoms include headache, weakness, nausea, seizures, memory difficulties, personality changes and vomiting.
