A polyp is a small growth that can develop on the lining of various organs in the body, such as the colon, stomach, or nasal passages. These growths are usually benign, meaning they are not cancerous, but some types can potentially become cancerous over time. Polyps can vary in size and shape, and they may be flat or raised. Polyps are often discovered during routine medical examinations, such as a colonoscopy for colon polyps. Symptoms may not be present, but some individuals might experience bleeding or changes in bowel habits. Regular screenings can help detect and remove polyps before they develop into more serious conditions.
