Breast Cncer and Gum Disease

The first study showing a link between breast cancer and periodontal disease was just published. The study was done at The Karolinska Instute and published in Breast Cancer Research and Treatment. Periodontitis seems to be closely associated with human cytomegalovirus and Epstein-Barr and Herpes virus co-infection. It is believed that these viruses act together to suppress immune response to bacterial challenges. The authors conclude that these viruses and bacteria act together to lead to low-degree chronic inflammation and carcinogenesis.
