The six-term Republican senator and former presidential nominee, who is 80, has been recovering at home in Arizona since undergoing a procedure to remove a blood clot from above his left eye.
Tissue analysis since that procedure revealed that a primary brain tumor known as a glioblastoma was associated with the clot, his office said.
