A woman smokes a cigarette during a break from work in downtown Chicago in 2006. New research published in the New England Journal of Medicine's issue coming out on Thursday, Jan. 24, 2013, finds that women who smoke today have a much greater risk of dying from lung cancer than they did decades ago, compared with those who never smoked.
