Gastrointestinal cancer includes organs such as the esophagus, stomach, small intestine, colon, rectum, anus, liver, bile duct and pancreas.
On the United European Gastroenterology Journal on June edition, Haydée WT Jordão, a scientist from the Center of Public Health Center at Queen’s University Belfast (UK), said that 28% of newly discovered cancers are found and 37% of cancer deaths in the UK 2018 are gastrointestinal cancer.
In the past, some research works indicated that poor dental health increased the risk of diseases such as diabetes, cardiovascular disease, stroke and cancer. To clarify the link between oral health and cancer, Mr. Jordão and his colleagues analyzed data of 469,628 people in 6 years.
They found out that as many as 4,096 people suffered from gastrointestinal cancer. 13% of these who suffered from dental problems such as pain and bleeding, loose teeth, are mainly patients with hepatocellular carcinoma, cancers in gallbladder or bile duct. The author group conclude that poor oral health can lead to a 75% increase in the risk of hepatocellular carcinoma, the most common type of liver cancer in adults.
Scientists are learning more about the cause of the link between oral health and liver cancer. According to Jordão, when suffering from the disease, the liver function is impaired, leading to the fact that harmful bacteria can live longer in the body, thereby harming the oral health. In addition, there is a bacterium type in the human mouth called Fusobacterium nucleatum but it is unclear for its role in liver cancer.
