According to a large study from the United Kingdom, people with poor oral health, including sore or bleeding gums or loose teeth, are at 75% higher risk of developing liver cancer.
For the study, a team of researchers analyzed data from 469,628 people, among whom 4,069 developed gastrointestinal cancer over an average follow-up period of 6 years. The researchers excluded individuals who reported insufficient detail about their oral health or who had a history of cancer when they joined the project.
The researchers say that scientists are not sure why poor oral health might have such a link to liver cancer. They suggest that the liver contributes to the elimination of bacteria from the human body.
