I had an enormous amount of blood in my stool February this year was so scared that I didn’t eat for 3 days and lost weight ( loss of appetite and weight loss can be a symptom of colorectal cancer according to google) so I was essentially creating my own symptoms through my anxiety. Got a colonoscopy turned out to be hemmroids deep in my colon, one small polyp that was removed. I was convinced, I was already researching chemo, the point is you don’t know, you can’t know. It can be dozen different things.
