PHOENIX — Sen. John McCain's blood clot above his left eye is associated with a primary brain tumor known as a glioblastoma, according to a statement released Wednesday by Mayo Clinic.
The 80-year-old McCain, R-Ariz., underwent cranial surgery on Friday. He is reviewing treatment options with his family. Those could include a combination of chemotherapy and radiation, according to the statement.
“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 Mayo Clinic said in its statement.
A written statement from McCain's office reiterated that the six-term senator, 2008 Republican presidential nominee and former prisoner of war in Vietnam is in "good spirits" as he recovers at his home in Arizona.
“He is grateful to the doctors and staff at Mayo Clinic for their outstanding care, and is confident that any future treatment will be effective," McCain's office said in the statement. "Further consultations with Senator McCain's Mayo Clinic care team will indicate when he will return to the United States Senate.”
U.S. Senate Majority Leader Mitch McConnell, R-Ky., released a statement regarding McCain Wednesday calling him "a hero to our Conference and a hero to our country."
McConnell wrote, "The entire Senate family’s prayers are with John, Cindy and his family, his staff, and the people of Arizona he represents so well.
“We all look forward to seeing this American hero again soon.”
McCain's daughter, Meghan McCain tweeted a statement saying all of the family has "endured the shock of the news, and now we live with the anxiety about what comes next."
She wrote that given her father's previous battle with cancer, which she called "familiar to the countless American families whose loved ones are also stricken with the tragedy of disease and the inevitability of age," the family was asking for prayers and would be "so grateful" for them.
