On Wednesday night, the office of John McCain and the Mayo Clinic released the following statement:
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.
Scanning done since the procedure (a minimally invasive craniotomy with an eyebrow incision) shows that the tissue of concern was completely resected by imaging criteria.
The Senator and his family are reviewing further treatment options with his Mayo Clinic care team. Treatment options may include a combination of chemotherapy and radiation.
The Senator's doctors say he is recovering from his surgery 'amazingly well' and his underlying health is excellent.
Glioblastoma is an aggressive form of brain cancer which makes up about 15% of all brain tumors worldwide. Surgery followed by chemotherapy and radiation therapy are typical treatment options, the cancer usually recurs. Glioblastoma is commonly found in males over 50 years old of a Caucasian, Asian or Hispanic background.
Senator Edward M. Kennedy and former Vice President Joe Biden's son, Beau, both passed away from the same cancer.
John McCain is an American hero & one of the bravest fighters I've ever known. Cancer doesn't know what it's up against. Give it hell, John.
