If you see these signs in your mouth, it could be colon cancer. Don't ignore this dentist's warning.

News Topical, Digital Desk : In the UK, someone is diagnosed with bowel cancer (colorectal cancer) every 12 minutes, and around 17,000 people die from the disease each year. It is the second most common cause of cancer death in the UK. People typically recognize its symptoms through signs like abdominal pain, changes in bowel habits, or diarrhea and constipation, but new research suggests that changes in the mouth could also be an early warning sign of this serious disease. 

The relationship between oral bacteria and the gut

Common problems with teeth and gums can indicate an imbalance of bacteria in the mouth. Harmful bacteria in the mouth can travel to the intestine and cause inflammation, which in some cases can contribute to the development of cancer. Certain habits, such as not brushing and flossing teeth properly, smoking, excessive alcohol consumption, and a diet high in sugar and low in fiber, can disrupt this delicate bacterial balance. 

Signs of colon cancer visible in the mouth 

1. Bleeding gums - Bleeding gums is a common symptom that indicates gum disease. It's a sign of inflammation and infection, allowing harmful bacteria to enter the bloodstream and reach the digestive tract. According to Harvard research, people with gum disease have a 17 to 21 percent higher risk of precancerous colon polyps. Additionally, swollen or tender gums, without visible bleeding, may indicate early gingival inflammation. This condition often remains asymptomatic and can go unnoticed for years. 

2. Bad breath - Persistent bad breath can also be a warning sign. It may be linked to a bacterium called Fusobacterium nucleatum, which has been found in gum disease as well as colon cancer tumors. This bacterium can travel to other parts of the body through saliva or blood cells and may evade immunity and contribute to cancer development. 

3. White or yellow coating on the tongue - A white or yellow coating on the tongue is caused by a buildup of bacteria, dirt, or dead cells. It can also be a sign of poor oral hygiene, dehydration, or dry mouth. Research suggests that some coatings may reflect changes in oral bacteria, which may be linked to colon cancer. 

4. Losing four or more teeth - According to Harvard and the AACR, people who have lost four or more teeth have a 20 percent higher risk of precancerous colon polyps. This can be the result of long-standing untreated gum disease.
