A number of studies show excess drinking, being overweight, and family history have strong correlations to increased risk of breast cancer. While researchers had previously questioned whether cigarette smoking was directly linked to increased breast cancer risk, they have recently found strong evidence for a link between the two.
THURSDAY, Feb. 28 (HealthDay News) — Cigarette smoking appears to increase the risk of breast cancer, especially when women start smoking early in life, new research indicates.
For years, experts have questioned whether cigarette smoking is directly linked with breast cancer risk or whether the association is complicated by the fact that many women who smoke also drink alcohol, which has also been tied to breast cancer risk.
Studies have produced conflicting results. When the U.S. Surgeon General last reviewed the issue in 2004, the report concluded that there was no cause-and-effect relationship between smoking and breast cancer risk.
