Instead, make a note of what you are experiencing. Record when it started, how often it occurs, whether it is getting worse, and whether other symptoms are appearing at the same time.
Then discuss persistent or concerning symptoms with a healthcare professional.
Depending on your symptoms and medical history, they may recommend blood tests, stool testing, imaging, colonoscopy, or another evaluation to determine the cause.
Remember that these symptoms can have causes other than cancer. Only appropriate medical evaluation can determine what is actually happening.
## The Bottom Line
Colon cancer can sometimes develop without obvious symptoms, which makes awareness and screening particularly important.
The eight warning signs to remember are:
1. **Blood in or on the stool**
2. **Persistent changes in bowel habits**
3. **Ongoing abdominal pain or cramping**
4. **Unexplained weight loss**
5. **Persistent or unusual fatigue**
6. **Unexplained iron-deficiency anemia**
7. **Persistent changes in stool shape or appearance**
8. **A combination of several concerning symptoms**
None of these signs automatically means you have colon cancer. But persistent, unexplained, or worsening changes deserve attention.
