Colorectal Cancer - Symptoms



The earliest sign of colorectal cancer may be bleeding. A person may notice that blood is produced during bowel movements. Blood can also be found in the feces. As the disorder develops, a person's pattern of bowel movements may change. The stools may change in size and become more narrow.

Other symptoms of colorectal cancer include general stomach discomfort, stomach cramps, gas pains, and diarrhea or constipation. The patient may feel that the bowel does not empty completely during a movement. Constant tiredness and weight loss for no known reason may also be a symptom.
