Hi, i'm a 22 year old male. Last year I had bright red blood in my stool once, but it disappeared after that one bowel movement. About 6 months later, a tiny bit of blood appeard on my toilet paper, and that was it. No blood since then. I eat a lot of fatty foods, yet I am not fat. I dont excercise that much. My stools are sometimes narrow, sometimes they are not. I used to hold in my poop a lot when I was younger, but i've stopped that ever since 6 months ago when I found that small amount of blood on the toilet paper. My family has no history of any cancer. I never have constipation, and I rarely have diarrhea. I never have problems with being fatigued, no weight loss (i've gained weight, actually, even though I have the same diet as I usual) and no pain. Finally, my whole life i've had problems dealing with certain kinds of greasy foods (hamburgers, pizza), and even though I know that they cause my stomach to ache so I have to take a bowel movement to get rid of the pain, I still eat these foods a lot. What are the chances that this is colon cancer?
