Overview
Colorectal cancer must be differentiated from other diseases that cause unexplained weight loss, unexplained loss of appetite, nausea, vomiting, diarrhea, anemia, jaundice, and fatigue, such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), hemorrhoids, anal fissures, and diverticular disease. There are less common conditions that may be confused as colorectal cancer such as infectious colitis and gastrointestinal lymphoma.

Other conditions that can be mistaken for colorectal cancer include the following:
- Benign colon polyps
- Ischemic colitis
- Infectious colitis
- Arteriovenous malformation (AVM)
- Carcinoid/neuroendocrine tumors
- Small intestine carcinomas
- Gastrointestinal lymphoma
- Ileus

- Appendicitis
- Hernia
- Lactose intolerance
- Flatulence
- Ulcer
