Innovative Results】Based on study on colorectal cancer screening in Xiacheng district,the results have showed that①The CRC screening in urban area based on guideline established by our units had the same good results as in rural area.High risk factors questionnaire investigation had important role in CRC screening and it can make up the shortcomings of iFOBT and detect nonbleeding lesions,especially precancerous lesions such as adenomas and polyps;②Each high risk factor was sorted according to sensitivity and specificity for the first time among natural population in city.
