People with periodontal disease, smokers and non-smokers have a higher risk of cancer.
Periodontitis increases the risk of cancer, according to a study published in the medical journal Cancer Epidemiology, Biomarkers & Prevention.
Researchers at the State University of New York at Buffalo and the Texas School of Dentistry in the United States conducted a study with medical data of 65,869 women aged 54 to 86 participating in the Women’s Health Initiative and suffering from periodontal disease and followed on average for more than 8 years. The researchers recorded a total of 7,149 cases of cancer.
The results of the study showed an increased risk of 14% of cancers for patients affected by periodontitis. There is a 3-fold increase in women with periodontal disease to develop esophageal cancer. Periodontitis increases the incidence of lung cancer, gall bladder, melanoma and breast cancer.
“The esophagus is in close proximity to the oral cavity, and periodontal pathogens can more easily access and infect the esophageal mucosa and promote the risk of cancer at this site in particular,” the authors of the study say.
The results of this study confirm the findings of researchers at Tufts University and the Elizabeth Platz School of Medicine at the Kimmel Cancer Center in the United States. They had previously found that participants with severe periodontal disease were twice as likely to develop lung cancer and had an 80% higher risk of colon cancer.
