The 76-year-old senator was diagnosed today with brain tumor known as a malignant glioma—the same diagnosis some 9,000 Americans receive each year. The average survival time ranges from 1 to about 5 years, reports the Boston Globe. Kennedy has already undergone a brain biopsy; one of his doctors said the course of treatment will be determined after more tests. "Senator Kennedy will remain at Massachusetts General Hospital for the next couple of days according to routine protocol. He remains in good spirits and full of energy," his medical team said in a statement. Read These Next We knew Letterman would pipe up about Colbert eventually.
