(AP) -- Taking menopause hormones for five years doubles the risk for breast cancer, according to a new analysis of a big federal study that reveals the most dramatic evidence yet of the dangers of these still-popular pills.
Even women who took estrogen and progestin pills for as little as a couple of years had a greater chance of getting cancer. And when they stopped taking them, their odds quickly improved, returning to a normal risk level roughly two years after quitting.
