Precancerous colon lesions

Illustrations of precancerous colon lesions

Precancerous growths in the colon most commonly appear as clumps of cells (polyps) that extend from the wall of the colon. Precancerous growths can also be flat or recessed into the wall of the colon (nonpolyps). Both polyps and nonpolyps can become cancerous, so doctors recommend screening tests to find and remove lesions in the colon.
