Goodday everyone,
I am 20 years old and have been tracking and reviewing my stool for a few days. Cancer runs in my family and has also been the cause of death for my father and my grandfather. saying that my grandfather worked for years as a fire brigade and always smoked and therefore always got bad polluted air and my father was discovered with bladder and colon cancer which turned out to be in him for about 10 years, which had also spread afterwards. he also smoked for years and ate junk all over the road as a truck driver. I myself have had some rumbling intestines with gas and very varied stools from an early age. doctors and hospitals have never really found a cause for this. I exercise a few times a week and also try to eat healthy. I don’t smoke either. lately I see my stool very different what I have tracked. I was wondering if you see anything strange or suspicious in my stool that might be useful to have it checked. I’ve had blood on the outside of my stool once or twice and occasionally what looks like dark brown mucus. I also have no gluten allergy or lactose intolerance. i would like to hear an opinion
