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.

Colorectal Cancer Differential Diagnosis
