"In October 2007, Sen. Kennedy had surgery to clear up a blocked left carotid artery (carotid artery stenosis).
In May 2008, Kennedy was rushed to Cape Cod Hospital from the Kennedy Compound after feeling ill and consulting with his physician, and then was subsequently transferred by helicopter to Massachusetts General Hospital in Boston. It was later reported that Kennedy had suffered two seizures, one initially at his Hyannis Port home and another on a helicopter en route to Massachusetts General Hospital from Cape Cod Hospital.
A few days later, doctors discovered that Kennedy has a
malignant glioma, a type of cancerous brain tumor."
