Margaret Thatcher is in the hospital after surgery to remove a growth from her bladder, but a spokesperson says the 87-year-old is "absolutely fine," reports the Guardian. Still, the former British prime minister might have to spend Christmas there instead of at home. Thatcher's health has been a concern since she suffered small strokes more than a decade ago, notes AP. She missed lunch with the queen this summer during Britain's royal jubilee celebration and her own 85th birthday party at 10 Downing Street. Last year's Iron Lady, with Meryl Streep, called attention to the dementia she has suffered from the strokes.
