Colorectal cancer often has no symptoms, which is why screening is so important. However, as it advances, there can be signs. If you have any of symptoms, tell your health care provider right away.
Don't ignore these symptoms:
- Unexplained changes in bowel habits that last for more than a few days, including diarrhea or constipation
- The urge to have a bowel movement that is not relieved once complete
- Bleeding, or stools that are dark or contain blood. However, sometimes stool may still look normal
- Pain or cramping in the abdomen
- Unexplained weakness or fatigue
- Unplanned weight loss
These may be signs of other conditions, including infections, hemorrhoids, irritable bowel syndrome, or inflammatory bowel disease. However, if you are experiencing any of these symptoms, don’t wait to call your doctor so the cause can be found and treated as soon as possible.
