Subtle changes in stool can be early signs of colon cancer. Symptoms like blood in stool, shifts in consistency, or altered bathroom habits may indicate trouble, though other digestive issues can cause similar changes.Key warning signs include narrow stools, rectal bleeding, tenesmus, abdominal pain, and fatigue. As cancer progresses, symptoms worsen,

with constipation, diarrhea, bloating, anemia, and potential blockages. Advanced stages may cause nausea, weight loss, and dark stools.Not all changes mean cancer, but persistent symptoms should be checked by a doctor. Early detection greatly improves treatment outcomes.
