Can you tell me how to tell if i have the signs of colon cancer?

Colon ca: In many cases, small cancer in the colon is found from the screening colonsocopy. When the cancer is small-usually no significant symptoms there. When the mass is bigger-symptoms like changing in bowel movement-constipation/diarrhea, thinning of the stool caliber, blood in the stool, abdominal pain, weight loss can happen. Iron deficiency anemia is noted quite frequently on initial presentation.
