Severe gum disease shows 24% increased cancer risk

Evidence mounts of link between severe gum disease and various cancers

Three recent studies have added further weight to the link between peridontitis and overall cancer risk.

The first showed that severe periodontitis was associated with a 24 percent increased risk.

The second and third investigated the role of bacteria causing periodontitis in the development of oral cancers and certain other cancers.

More evidence of link between severe gum disease and cancer risk

Data collected during a long-term health study provides additional evidence for a link between increased risk of cancer in individuals with advanced gum disease, according to a new collaborative study led by epidemiologists Dominique Michaud at Tufts University School of Medicine and Elizabeth Platz of the Johns Hopkins Bloomberg School of Public Health and Kimmel Cancer Center.

The study, published in the Journal of the National Cancer Institute, used data from comprehensive dental exams performed on 7,466 participants from Maryland, Minnesota, Mississippi, and North Carolina, as part of their participation in the Atherosclerosis Risk in Communities (ARIC) study who were then followed from the late 1990s until 2012.

During the follow-up period, 1,648 new cancer cases were diagnosed.

The research team found a 24 percent increase in the risk of developing cancer among participants with severe periodontitis, compared to those with mild to no periodontitis at baseline.
