The efficient screening for colon cancer, especially for those deeper than sm tumor, was studied in 1017 cases of invasive carcinomas found among the 31, 070 patients who had undergone the initial screening test for colon cancer using TCS in our center from 1992 through 1998. The results are as follows.(i) In order to detect colon cancer efficiently, screening is recommended for all individuals beginning at the ages of 40 years for men and 30 years for women.(ii) Performing only a single TCS screening yields quite satisfactory results.(iii) When m tumor or adenoma is detected at the first screening, male patients should undergo a second screening in three years; the efficient time of the second screening for women cannot be determined.(iv) When a neoplastic region is not detected at the first screening, the second screening can wait until 5 years later for both men and women.(v) A third screening may not be necessary for the present for both men and women.
