Symptoms

Some people who have metastatic or recurrent colorectal cancer do not have any symptoms. When they do appear, the most common symptoms are:

• A change in bowel habits, such as narrow stools or frequent diarrhea or constipation.
• Blood in the stool, or stools that look like black tar.
• Loss of appetite.
• Pain in the belly.
