Sen. John McCain, 80, Diagnosed With A Form Of Aggressive Brain Cancer
Sen. John McCain, 80, has been diagnosed with a primary glioblastoma, a type of brain tumor, Mayo Clinic doctors directly involved in the senator's care told CNN exclusively. The doctors spoke directly to CNN Chief Medical Correspondent, Dr. Sanjay Gupta.

The senator underwent surgery to remove a blood clot on Friday at Mayo Clinic Hospital in Phoenix. Lab results from that surgery confirmed the presence of brain cancer associated with the blood clot.
Glioblastoma is a particularly aggressive tumor that forms in the tissue of the brain and spinal cord, according to the American Brain Tumor Association.

A pathologist was in the operating room during the procedure, a minimally invasive craniotomy with an eyebrow incision, said his doctor, who added that the surgery lasted about three to four hours. Post-surgical brain scans show the tissue causing concern has been completely removed.
