Learn About the Symptoms of Colon Cancer

Colorectal cancers—cancers of the colon or rectum—begin as noncancerous clumps of cells called polyps, which may become cancers over time. Recognizing the signs of colon cancer and rectal cancer can lead to early detection and more effective treatment.

Colorectal cancer may cause one of more of the following symptoms:

  • A change in bowel habits such as diarrhea, constipation or narrowing of the stool that lasts for more than a few days
  • A sense of urgency or bowel fullness that isn’t relieved by a bowel movement
  • Rectal bleeding
  • Blood in the stool, or dark stool
  • Persistent abdominal discomfort, such as cramps, gas or pain
  • Unexplained weight loss
  • Weakness or fatigue

Colorectal cancers may bleed into the digestive tract, and bleeding can occur even if the stool looks normal. Over time, this blood loss can lead to low red blood cell counts or anemia. In some cases, a blood test showing anemia is the first sign of colorectal cancer.

When to See a Doctor

If you notice any symptoms associated with colon cancer, such as a persistent change in bowel habits or blood in your stool, make an appointment with your physician. He or she can advise you about when you should begin screening for colorectal cancer.

Guidelines generally recommend that colorectal cancer screenings begin at age 50, but you may benefit from more frequent screenings if you have other risk factors, such as a family history of colorectal cancer.
