From September 1977 to April 1978 in Haining County, a general survey of colorectal cancer was performed on people over the age of 30, and appropriate treatments were given to patients with colorectal cancer and intestinal polyps. In October 1979, these cases were followed up. Since the end of the first screening for colorectal cancer from May 1978 to October 1979, 15 new cases of colorectal cancer have been newly discovered, and 9 cases have died of colorectal cancer. Therefore, the annual mortality rate after census Analyze and discuss with annual incidence to explore the significance of the census.
