Black or Tarry Stool: A Possible Indicator of Colon Cancer
A potential indication of colon cancer is the presence of black or tarry stool. When there is bleeding in the upper part of the colon, it can lead to stools with this atypical appearance. The blood produced in the higher regions of the colon undergoes a breakdown process before being expelled from the body. Additionally, bleeding from the stomach, esophagus, or small intestines can also contribute to the development of tarry stools. If your bowel movements take on the consistency and appearance of tar, it is crucial to consider this as a highly concerning sign that could be associated with colon cancer.
Cramping or Pain
When colon cancer advances, it can cause irritation in the lining of the intestines, resulting in cramping and pain. It is important to note that this symptom is not exclusive to colon cancer and can also be caused by infections, inflammatory conditions of the bowel, or even menstruation. It is worth mentioning that it is possible to have colon cancer without experiencing any pain or cramping at all. However, if you do experience this symptom for an extended period of time, particularly if you notice any other accompanying signs, it is crucial to consult with a doctor.
