Colorectal Cancer Symptoms

There are no symptoms of colorectal cancer while it is in the early stages, which is why screening is critical. With advanced cancers, symptoms might include:

• changes in bowel habits, such as diarrhea, constipation or a narrowing of the stool that lasts for more than a few days;
• abdominal cramps;
• Weight loss;
• a feeling that you need to have a bowel movement even after doing so;
• weakness and tiredness; or
• bleeding from the rectum or blood in the stool
