Researchers at the American Cancer Society have found an increased breast cancer risk among women who smoke, especially those who start smoking before they have their first child. Researchers analyzed data from 73,388 women in the American Cancer Society’s Cancer Prevention Study II (CPS-II) Nutrition Cohort. During more than 13 years of follow-up, researchers counted 3,721 cases of invasive breast cancer. The rate of new cases was 24% higher in smokers than in nonsmokers and 13% higher in former smokers than in nonsmokers. Read more here.
