Does listerine cause colon cancer?

There is no scientific evidence that using Listerine or other mouthwashes causes colon cancer.

Listerine is a mouthwash that primarily contains alcohol and other antimicrobial agents to kill bacteria in the mouth and support oral hygiene. It is used as a mouthwash and does not come into contact with the colon.

There are some studies that associate the use of high-alcohol mouthwashes with an increased risk of oral cancer with very heavy use, especially in people who also smoke or drink a lot of alcohol. However, this association has nothing to do with colon cancer.

For the colon, the main risk factors include genetics, diet (such as a diet high in red and processed meat), smoking, alcohol consumption, lack of exercise, and certain chronic bowel diseases.

On social media, it is claimed that Listerine users have the same bacteria in their mouths as people who get colon cancer. However, a causal link has not been proven. Listerine can therefore still be used safely.

If you are concerned about colon cancer, it is better to focus on a healthy lifestyle, regular medical check-ups (such as screenings for people over 50 or at-risk groups), and a high-fiber diet.
