Intro: Researchers from the Mayo Clinic have reported that women who have smoked 100 or more cigarettes in their life have a significantly increased risk of developing breast cancer. The details of this study were published in the September-October 2009 issue of The Breast Journal.[1]
Although both active and passive smoking are known to increase the risk of lung cancer, findings for breast cancer have been mixed. A recent review of published studies suggests that both active and passive smoking may increase the risk of breast cancer—particularly premenopausal breast cancer. The following observations were made from this review of 19 studies:
* Passive smoking increased the risk of breast cancer by 27%.
* Among premenopausal women, passive smoking increased risk of breast cancer by 68%. . . .
