Arizona Sen. John McCain has been diagnosed with brain cancer, the Mayo Clinic Hospital in Phoenix says. McCain, 80, underwent surgery for a blood clot on July 14.

The hospital says testing revealed that a tumor "known as a glioblastoma was associated with the blood clot."

"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 hospital statement said.
