Sen. John McCain diagnosed with brain cancer

Senator John McCain (R-AZ) has brain cancer, according to a statement released by the Senator's office.

The office released the statement, shortly after 5:00 p.m. Wednesday. News of the diagnosis came, days after Sen. McCain underwent a procedure to remove a blood clot from above his left eye at Phoenix's Mayo Clinic on July 14.

According to the statement, a primary brain tumor known as a glioblastoma was associated with the blood clot. A minimally invasive procedure that involved a craniotomy with an eyebrow incision was done, and scanning done since the procedure shows the tissue of concern was completely resected.

Sen. McCain's doctors said he is recovering well from the surgery, and that his underlying health is "excellent". In addition, Sen. McCain and his family are reportedly reviewing further treatment options with a care team at Mayo Clinic, which may include a combination of chemotherapy and radiation.
