 We have studied differential diagnosis by radiograph between m/sm1 and sm2/3 in 409 lesions (m cancer:331, sm cancer : 78). An invasive cancer (sm2/3) of the pedunculated type has an uneven nodular surface, a depressed area or is 1.1 cm in diameter. A sm2/3 of the sessile type has a double margin or a depressed area. In a sm2/3 of plaque-like type we have not pointed out any characteristic findings. In a sm2/3 of depressed type a relatively wide marginal elevation around the depressed area, a deep barium fleck or converged mucosal folds are recognized by radiology.

 These radiological findings in sm2/3 can be demonstrated by a well prepared for barium enema investigation.
