You should begin regular colon cancer screening at age 50, but look out for the following colon cancer symptoms at any age:

• Blood in your stool

• Changes in your bowel movements for more than a few weeks or a feeling that your bowels aren't empty after a movement

• Fatigue

• Frequent abdominal pain, cramps or gas

• Rectal bleeding (sometimes confused with hemorrhoids)

• Unexpected weight loss.
Symptoms vary depending on the stage and location of the cancer. Consult your doctor if you are experiencing these symptoms.
