Hello doctor sir I have anal fissure from last 5 years approx like whenever hard stool for 2-3 days blood and little discomfort present its cyclic type like whenever hard stool blood come with Anus and little discomfort also I showed it to a doctor earlier also and now also doctor told it's chronic fissure because of which the pain is very minimal only not typical fissure pain and but bleeding occurs he told no need of any treatment because pain and discomfort is not there and at yours age which is 19 surgery is not good option as no discomfort but as it occurs when stool is hard eat less spicy less masala food and take more fibre food so that the stool is soft and no bleeding so sir it's okay to leave that chronic fissure like that without any treatment i am worried because I read in Google that chronic fissure may turn into fistula and cancer is that' true sir please tell can this fissure turn into cancer anal cancer please tell because my doctor told don't worry no treatment needed
