New Evidence Suggests Smoking May Increase Breast Cancer

More evidence that women who smoke are increasing their risk of breast cancer.

A new study looked at more than 116,000 teachers in California, all women. They found that the smokers had a 30% greater risk of developing breast cancer than the women who did not smoke.

So, what about women who had smoked, but quit? Researchers found those ex-smokers still had an increased risk for breast cancer if they began smoking at an early age or smoked heavily before their first pregnancy.

The theory is that breast tissue in young women may be more sensitive to exposure to toxic agents. The study is published in the Journal of the National Cancer Institute. The study was conducted by researchers at the California Department of Health Services in Oakland, California and the University of California School of Medicine in Irving, California.
