May be none: Many early cancers do not have any symptoms and that is why it is important to have screening tests done, e.g., colonoscopy at age 50 for prevention of colo-rectal cancer. Symptoms may be change in bowel habits, bleeding per rectum, anemia, bowel obstruction and the first symptoms may be from metastases to other organs such as liver.

Few if any: Colon cancer is generally a very silent disease until it is advanced often early stage i and ii cancers will have no symptoms which is why routine screening colonoscopy is so important. Abdominal pain rectal bleeding unexplained weight loss fatigue may all be associated with a more advanced cancer. Total obstruction or perforation may be found in bet advanced cancers.

Often "silent": Unfortunately, colon cancers may develop "under the radar" for quite some time before symptoms occur. The earliest sign is usually anemia caused by a slowly bleeding tumor. As the cancer grows, it may block the colon causing cramping pain, bloating, and/or pencil-thin stools. The gold standard for diagnosing colorectal cancer is screening colonoscopy at age 50, or earlier with a family history.

Blockage, Bleeding: The most common symptoms associated with colon cancer include (cramping) abdominal pain, a change in bowel habits ("pencil-thin stools"), bloody bowel movements, weakness/fatigue, and/or weight loss. The goal, of course, is to diagnose colon cancers before symptoms develop; i advise colonoscopy at age 50, or earlier if there is a family history.
