Senator Edward Kennedy diagnosed with brain tumor; prognosis seen as poor May 20, 2008 04:32 PM By Carey Goldberg and Brian Mooney, Globe Staff US Senator Edward M. Kennedy, the veteran lawmaker from Massachusetts who is the last surviving brother in the legendary Kennedy family, has been diagnosed with a malignant brain tumor, his doctors said today. Specialists in Boston and around the country said the information released indicated that Kennedy has terminal cancer and might have only a limited time to live. Kennedy's doctors at Massachusetts General Hospital, who had been investigating the cause of a seizure that led to Kennedy's hospitalization this weekend, said that preliminary results from a brain biopsy indicated the seizure had been caused by a tumor in the top left portion of his brain. The usual course of treatment for the tumor -- a malignant glioma -- includes combinations of various forms of radiation and chemotherapy, Dr. Lee Schwamm, vice chairman of the neurology department at the hospital, and Dr. Larry Ronan, Kennedy's primary care physician, said in a statement. The doctors said decisions regarding the best course of treatment for the 76-year-old senator would be determined after further testing and analysis. But other specialists said that the diagnostic details released by the hospital indicated that Kennedy has terminal brain cancer and most likely less than three years to live -- perhaps much less.
