Senator Ted Kennedy is recovering at Duke University Hospital after undergoing risky brain surgery for a malignant tumor.
Hospital officials say he enjoyed a restful night's sleep and was walking the hospital hallways Tuesday after the three-and-a-half-hour procedure.
Doctors gave out few details about Monday's surgery, but the lead surgeon did release a statement.
The surgery "was successful and accomplished our goals," the Los Angeles Times quoted Kennedy's neurosurgeon, Dr. Allan Friedman.
Friedman said that Kennedy was awake during the entire procedure and would likely experience no permanent neurological effects from the operation, according to the Times.
The senator reportedly said to his wife, Victoria Reggie Kennedy, right after the surgery: "I feel like a million bucks. I think I will do that again tomorrow."
Kennedy's type of tumor invades normal tissue making surgery complicated. But the three-and-a-half-hour operation involved removing as much of the tumor as possible.
Kennedy, 76, was awake during most of the surgery, which helps doctors avoid vital areas of the brain.
"The patient is talking, naming, repeating," said Dr. Matthew Ewend. "You want him doing language function and then if you stimulate small areas of the brain and if that function stops, then you that is a critical area. And you know one can't go through it for surgery."
While he remains in the hospital, he probably will be given drugs to prevent brain swelling and seizures. He will also be monitored for bleeding and blood clots, since there is a risk of a possible stroke.
Following his return home in about a week, the Massachusetts senior senator will undergo radiation and chemotherapy to aggressively fight the cancer.
In a statement released by his office, Kennedy said he was "humbled by the outpouring" of prayers from around the world, the senior senator from Massachusetts thanked those who had "expressed their support and good wishes as I tackle this new and unexpected health challenge."
