Symptoms of colorectal cancer may include:

  • Bowel habit changes, such as diarrhea, constipation and stool narrowing; these last for more than a few days
  • Feeling that your bowel does not empty completely
  • Rectal bleeding, dark stools or blood in stools (the stool itself may look normal)
  • Cramping or abdominal pain
  • Weakness and fatigue
  • Unintentional weight loss

If you have any of these symptoms, see your healthcare provider right away to get an accurate diagnosis. In most cases, these symptoms are caused by less-serious conditions, such as hemorrhoids, infection, irritable bowel syndrome or other bowel conditions. However, your physician is the best person to make that determination. If symptoms are related to colorectal cancer, the sooner you get treatment; the earlier the diagnosis, the better the chance of cure.
