Active smoking and the risk of estrogen receptor-positive and triple-negative breast cancer among women ages 20 to 44 years.

摘要

The current results suggested that young women who are current/recent smokers with high pack-year histories may have an increased risk of ER-positive breast cancer but not TN breast cancer. Although this association was modest, the findings suggest that an increased risk of ER-positive breast cancer may be another health risk incurred by young women who smoke.
