Good Oral Health Greatly Cuts Liver Cancer Risk, new study finds

The study, by researchers at Queen's University Belfast, analysed a large cohort of over 469,000 people in the UK, investigated the association between oral health conditions and the risk of a number of gastrointestinal cancers, including liver, colon, rectum and pancreatic cancer. Models were applied to estimate the relationship between cancer risk and self-reported oral health conditions, such as painful or bleeding gums, mouth ulcers and loose teeth.

Whilst no significant associations were observed on the risk of the majority gastrointestinal cancers and poor oral health, a substantial link was found for hepatobiliary cancer.

"Poor oral health has been associated with the risk of several chronic diseases, such as heart disease, stroke and diabetes", explained Dr. Haydée WT Jordão, from the Centre of Public Health at Queen's University Belfast and lead author of the study. "However, there is inconsistent evidence on the association between poor oral health and specific types of gastrointestinal cancers, which is what our research aimed to examine."
