Sen. Edward Kennedy waves as he rides on a pier after going for a sail Monday in Hyannis Port, Mass.

Fresh from his hospitalization for an aggressive surgery on a cancerous brain tumor, Sen. Edward M. Kennedy announced it was "good to be home" at his family's Cape Cod compound Monday and headed out for a sail.

Kennedy left the Duke University Medical Center in Durham, N.C., on Monday morning and arrived at his family's Hyannis Port compound just before noon. With his thick white hair visible beneath a beige, wide-brimmed hat, he told reporters he felt "good to be home, good to be here."

Within hours, he went out sailing with his wife, Vicki. It was the same homecoming routine he followed last month when he was released from a Boston hospital after being diagnosed with a malignant glioma, a lethal type of brain tumor. A malignant glioma is one of the worst kinds of brain cancer, and malignant gliomas are diagnosed in about 9,000 Americans a year.
