If the colonoscopy was done two years ago, it is not certain to judge whether you will get bowel cancer now, you need to combine with the previous examination results and colonoscopy again to make it clear. If there is no obvious colorectal organic lesions in the colonoscopy report two years ago, the risk of patients inducing intestinal malignant tumors within two years is very low, and it is recommended that the patients can do a good job of regular review, avoiding irregularities and bad dietary habits. If the electronic colonoscopy report two years ago shows that there are colon polyps or the appearance of low-grade adenomas and other related precancerous lesions, if there is no active resection treatment, the risk of localized intestinal polyps inducing malignant tumors within two years is high, and it is necessary to review the electronic colonoscopy every six months to one year. Specifically whether there will be bowel cancer at present should be clarified by further colonoscopy and pathology examination, and it is recommended to determine the examination and treatment plan according to the specific situation under the guidance of professional doctors.
