I wanted to know iif there is signs of colon cancer? and if so what are they

Blood in stool: Either gross red blood, melena or black stool, or occult blood; pain and cramping. But these are signs of advanced cancer. Early diagnosis is key to successful treatment, and that is why doctors recommend screening colonoscopy at age 50. Under age 50, colon cancer is rare unless you have some predilection to it, such as ulcerative colitis or polyposis. Ask your dr for specific recommendation.

Variable: From no signs at all to rectal bleeding, change in bowels, more diarrhea or constipation, abdominal pain, change in stool caliber. But many patients have no symptoms at all. If you are over 50 or if you have a family history or any of the above symptoms, see a colorectal surgeon for evaluation and colonoscopy if indicated.
