Is Gum Disease a Cancer Risk Factor?

Seems like an odd correlation, but a recent study published in Cancer Epidemiology Biomarkers & Prevention suggests so. The study found that, in postmenopausal women, those who had gum disease had a 14% higher chance of developing any type of cancer. The greatest cancer risk with gum disease was esophageal cancer, where there was a threefold increased chance of developing it.
Researchers followed nearly 66,000 women ages 54 to 86 for up to 15 years. They identified 7,149 cancer cases. The findings for the gum disease-cancer correlation existed among women who never smoked, too.
Researchers do not yet see a direct link between cancer and gum disease, however they are calling for more investigation of this correlation. It could be that gum disease is just an indicator of poor health overall which is a risk factor for cancer. However, in the meantime be sure to keep track of your dental health. Fighting off gum disease today might keep you healthier tomorrow.
