What are the symptoms of colorectum / anal cancer? What are the possibilities of a healthy 23 year old who does not smoke drink vegetarian and no family history of cancer of any kind having colon rectum n anal cancer? I have the following problem since yesterday. I traveled to a place which was super hot and I dint keep myself hydrated at all bcuz of this when I went to pass motion I had to strain myself a lot. Then the 2 other times that I used the toilet, there was no pain the stool was ok with no blood but had little mucus. But after I cleaned the anal area with water I saw a little bloody mucus coming out and when I put water I get a pricking sensation. I had Anal fissure a month back which was cured with medicines. I read about colon rectum n anal cancer on Google. And now m very scared bcuz the symptom they mentioned are same as mine. Can I get a clear guidance from a doctor on this? I know this problem is something that should be examined. And I will go to a doctor in person. But as off now only this one question is bothering me whether the symptoms I mentioned suggest cancer?
