Maybe none: First signs may be invisible rectal bleeding, changes to bowel function. Early colon cancers will have no symptoms. Colonoscopy is a way to find a colon cancer early.

Colon cancer: Blood in the stool, whether or not you can see it, in addition to abdominal pain and bloating, constipation or diarrhoea which persists without explanation for more than a few days. Change in stool caliber is also sometimes noted.

Bleeding, wt loss: Most colon cancers are found at screening endoscopy when they are not causing symptoms. When there are symptoms, those of anemia (short of breath, pale, tired) are common because the tumor bleeds. Colon cancer can also cause bowel obstruction with severe colicky pain, or loss of appetite and weight.

Here are some...: Every life event including colon cancer not only is a process of lifelong making, but displays on its pattern of full spectrum. Likewise, for colon cancer, at its early stage, no symptom but incidental finding found on routine colonoscopy; at its late stage, gross colon bleeding or bowel obstruction may evidence; at its middle path, symptoms are in between.

Medium sign: When colon cancer starts to bleed, it shows up as occult blood in stool. As it bleed more, the stool color will turn black or red. Then, when your bone marrow, which makes blood cells, cannot keep up with the blood loss, you get signs of anemia. Then as cancer advances, you can get obstruction or perforation., or even spread to liver or other organs. Important to catch earlier than anemia.

Gastroenterologist: I would immediately consult with a gastroenterologist or colorectal surgeon. You may need simple blood tests and perhaps a colonoscopy to determine what is going on along the internal lining of your entire colon before determining whether or not you have an actual lesion. Other imaging studies may be performed as well.

Fly Under Radar: Colon cancer rarely causes symptoms until it reaches a size large enough to obstruct the intestine (change in bowel habits) and/or cause anemia due to chronic bleeding (weakness, lethargy, sob) and/or perforate ("acute abdomen"). Colonoscopy offers people the best opportunity to find these cancers well before any symptoms develop, when the chance for cure is very high. Please get one (if 50 & up).
