New York: Postmenopausal women with periodontal or gum disease are more likely to develop breast cancer than women who do not have the chronic inflammatory disease.
"One possible explanation for the link between periodontal disease and breast cancer is that those bacteria enter the body's circulation and ultimately affect breast tissue," said Jo Freudenheim, professor at University at Buffalo in New York.
Periodontal disease is a common condition that has been associated with heart disease, stroke, and diabetes.
The researchers monitored 73,737 postmenopausal women enrolled in the Women's Health Initiative Observational Study, none of whom had previous breast cancer. Periodontal disease was reported in 26.1 percent of the women.
The researchers found that among all women, the risk of breast cancer was 14 percent higher in women who had periodontal disease.
