It's new information released in the New England Journal of Medicine, information that shows the risk of death from smoking is much higher in women than previously thought. There's also surprising new data on the benefits of quitting. NPR's Richard Knox has the story.
First, the under-appreciated risk of smoking for women. Dr. Prabhat Jha, an author of one study, says before now, not enough women had been smoking long enough to gauge their true risk.
The group of women that started smoking seriously in and around 1960s, can be followed up only now, fully five decades later, to understand what are the full consequences of smoking among women.
In the 1980s, it looked like women who smoked were about 13 times more likely to die from lung cancer than women who never did. But the new analysis finds that female smokers are more than 26 times more likely to die of lung cancer than nonsmoking women, and their risk of death from any cause is 50% higher than previously thought.
