8. Unexplained Lower Back Pain
While back pain is often linked to muscle strain, persistent lower back pain can sometimes be a sign of advanced colon cancer. If the tumor presses on surrounding organs or nerves, it may cause referred pain in the lower back or pelvis.
9. Frequent Urinary Issues
Though colon cancer primarily affects the digestive system, tumors in the lower colon can press against the bladder or urinary tract, leading to frequent urination, difficulty urinating, or an increased risk of urinary tract infections (UTIs).
10. Dark or Tarry Stools
Blood in the stool is a well-known sign of colon cancer, but not all blood appears bright red. In many cases, internal bleeding from higher up in the colon causes stools to become dark, tarry, or even black. These changes may go unnoticed, but they indicate the presence of digested blood, which requires immediate medical attention.
Conclusion
Colon cancer is often called a silent killer because its early symptoms can be subtle or mistaken for less serious conditions. Paying attention to unusual signs like unexplained weight loss, chronic fatigue, stool changes, persistent cramps, and anemia can lead to early detection and better treatment outcomes.
If you notice any of these symptoms, especially if they persist for more than a few weeks, consult a doctor for proper evaluation. Regular screening tests, such as colonoscopies, stool tests, and blood tests, are crucial in catching colon cancer early, when it is most treatable.
