Sen. Ted Kennedy has been diagnosed with a malignant brain tumor and will remain hospitalized for at least several additional days as he and his family determine treatment options.
The Massachusetts Democrat suffered a seizure Saturday and has since been hospitalized at Massachusetts General Hospital in Boston. He has been talking and joking with family and friends while undergoing a battery of tests that revealed the malignant tumor, a glioma in the left parietal lobe, according to the hospital.
"He has had no further seizures, remains in good overall condition and is up and walking around the hospital," Drs. Lee Schwamm and Larry Ronan said in a joint statement released by the hospital.
"The usual course of treatment includes combinations of various forms of radiation and chemotherapy," they said. "Decisions regarding the best course of treatment for Sen. Kennedy will be determined after further testing and analysis."
Kennedy, the second-longest serving senator in U.S. history, has represented Massachusetts in the Senate since 1962.
"Tough days ahead," a Kennedy family friend told ABC News, "but (Senator Kennedy is) in fighting mood." Another Kennedy family member said they are bringing in another doctor for further evaluation adding, "This is not a good time."
Vicki Kennedy, the Senator's wife, informed Senate Majority Leader Harry Reid, D-Nev., Tuesday afternoon of Kennedy's diagnosis. Reid, in turn, informed the Senate Democratic caucus at their weekly luncheon on Capitol Hill.
