How Your Bowel Movements Reveal Clues About Colon Cancer
I used to think only major symptoms indicated serious issues, but I’ve learned that subtle changes in your stool can be an early warning for colon cancer. Blood in the stool, changes in consistency, or frequency of bowel movements could point to a problem, though other digestive disorders can cause similar symptoms. It’s important to be aware of what to look for and consult a healthcare professional if something seems off.
Early Indicators of Colon Cancer:
- Narrow stools (due to tumor narrowing the bowel)
- Pain during defecation
- Incomplete bowel emptying (common with rectal cancer)
- Rectal bleeding
- Abdominal pain and fatigue (due to blood loss)
Changes in Stage 3 Colon Cancer:
- Constipation, diarrhea, or alternating between the two
- Blood in stool (from red to dark)
- Increased abdominal bloating and cramps
- Iron deficiency anemia
In Advanced Colon Cancer (Stage 4):
- Dark, sticky stool (melena) if the tumor is on the right side
- Nausea, vomiting, and unexplained weight loss
- Perforations or spread to other organs
Key takeaway: Minor changes in your stool can signal colon cancer. If you notice persistent changes, see a doctor. Early detection makes the disease more treatable.
