Dentists at the University of Louisville report a possible link between gum disease bacteria and esophageal cancer.
Doctors say 61% of cancer patients in their study also had p-Gingivalis. For the study, researchers tested tissue samples from 100 patients with esophageal cancer and 30 healthy patients.
The results showed both the gum bacteria enzyme was significantly higher in the cancerous tissue of the cancer patients than in surrounding tissue or normal control sites. Researchers hope the bacteria may one day be used to help detect the deadly cancer.
