Stomach constantly gurgling with pain at belly button, pain does not migrate. is this a sign of colon cancer?

Don't live with pain: Colon cancer (or most abd. Cas) in 20 yo s. is really rare. Not to say your pain should be ignored as ulcers and other inflammatory diseases can be present. Much depends on a detailed history to include bowel habits. See a family doc.; good to have one anyway.

No: Colon cancer at your age is highly unlikely. Gurgling is from movement of gas in the intestine. You may need to adjust your diet through trial and error. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
