Overview
The exact incidence and prevalence of colon polyps are unknown. Colon polyps are incidentally found in colonoscopies and sigmoidoscopies. However, the incidence of colon polyps is estimated to be 200,000 cases in the united states annually. The prevalence of colon polyps is between 10,000-25,000 in 100,000 screening studies. The incidence of colon polyps increases with age; the median age at diagnosis is 50 years. Colon polyps usually affect individuals of the African American race. Men are more commonly affected by colon polyps than women. Colon polyps is a common disease worldwide.
