Senator Edward Kennedy dies from brain cancer

WASHINGTON (VOA) — Senator Edward Kennedy, a legendary political figure in the United States, died on Tuesday after a year long battle with malignant glioma, the most common type of brain cancer among adults.  Although he had the most up to date treatments — surgery at Duke University Medical Center, chemotherapy and radiation — he was not able to survive the disease.  Doctors still don’t know what causes brain tumors and the National Cancer Institute says the outlook for patients with malignant gliomas is poor.  VOA’s Carol Pearson has more.
