If you have colon or rectum cancer, you may not experience noticeable symptoms in the early stages of the disease. When you do experience symptoms, they will vary based on the size and location of the cancer in your large intestine.

The symptoms of colorectal cancer may resemble those of other conditions, such as infections, hemorrhoids, and inflammatory bowel disease. It is also possible to have colorectal cancer and not have any symptoms. Always consult your physician for a diagnosis.

The following are the most common symptoms of colorectal cancer. However, each person may experience symptoms differently.

  • A change in bowel habits—such as diarrhea, constipation, or narrowing of the stool—that lasts for more than a few days
  • Bright red or very dark blood in the stool
  • Discomfort in the stomach area, such as frequent gas pain, cramps, and feelings of being full or bloated
  • Constant weakness and fatigue
  • Jaundice - yellowing of the skin and eyes
  • Weight loss for no known reason

If you have any of these symptoms, you should check with your physician, especially if you are over 50 or have a personal or family history of the disease.
