We all know how bad breath can be embarrassing at times. In most cases, it is associated with oral or dental hygiene. But emerging studies are revealing something more concerning and life-threatening.

Bad mouth odor is associated with one the most rising forms of cancers- colon cancer. Recently, Florida-based gastroenterologist Dr. Joseph Salhab (@thestomachdoc), shared an instagram post, where he explained this shocking link.

What is colon cancer

Colon or colorectal cancer is cancer that starts in polyps on the inner lining of the colon and rectum. Colon cancer is a type of cancer that can affect the colon or rectum.Research shows that in general, having colon cancer can reduce lifespan by about 10 years.

How long one lives after the treatment depends on factors like age, the cancer stage at diagnosis, treatment and health, notes Cleveland Clinic.

How bad breath is linked with colon cancer

Dr. Salhab notes that bad breath might be more than just embarrassing, as it could be a warning sign. He further explains:

• Fusobacterium nucleatum is a bacteria that lives in the mouth, especially in plaque and infected gums.
• He adds, scientists have discovered this same bacteria in colon cancer tumors.
• Research shows that F. nucleatum can actually travel from your mouth to your intestines, where it helps cancer cells grow and spread.
• Studies found way more of this bacteria in cancerous tumors than in healthy colon tissue.

Oral hygiene beyond bad breath

Dr. Salhab says while poor breath can also be a sign of poor gut health, it should not be neglected. He notes, oral health and colon health are linked in ways that researchers are only beginning to understand. The gastroenterologist recommends avoiding excess sugary snacks and drinks, brushing and flossing properly.
