WASHINGTON — 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.
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 glioblastoma 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 3 to 4 hours. Post-surgical brain scans show the tissue causing concern has been completely removed.
