The early stages of CRC may not produce notable, obvious symptoms. It is possible to have CRC without any symptoms. Over time, as polyps grow, they have a tendency to intermittently bleed or block the intestine. Therefore, people with the following conditions should consult their physician, as they may be an indication of CRC:1

  • A change in bowel habits such as diarrhea, constipation, or narrowing of the stool that lasts for more than a few days
  • A feeling that you need to have a bowel movement that is not relieved by doing so
  • Rectal bleeding or blood in the stool (often, though, the stool will look normal)
  • Cramping or steady abdominal (stomach area) pain
  • Weakness and fatigue

It is important to keep in mind that these symptoms can be the result of other conditions, including infections, hemorrhoids, and inflammatory bowel disease.
