Colon Cancer: Symptoms, Causes & Detection

Colon cancer results from cells in the large intestine mutating and growing uncontrollably. These tumors are often preceded by small growths called polyps. Colon cancer can occur anywhere in the large intestine, as well as the rectum and appendix. Symptoms of colon cancer tend to be localized until it metastasizes to another location.

Bowel movements

• People with colon cancer may experience constipation or diarrhea and may have mucus or blood in their stools.

Tumor

• In some cases, the tumor itself can be felt by a physician doing an abdominal exam.

Urinary symptoms

• The tumor may break down the walls of the bladder, which can cause blood or air in the urine.

Systemic symptoms

• All sorts of cancer can cause sudden weight loss and a lack of appetite.

Symptoms of metastases

• Colon cancer most commonly metastasizes to the liver, where it can cause jaundice and liver pain. It can also lead to blood clots.
