Rectal Bleeding
Rectal bleeding can be a symptom of colon cancer, especially when the bleeding occurs in the lower digestive passage. It is possible for the bleeding to happen directly in the rectum. When rectal bleeding occurs, blood can be seen as a distinct discharge in the stool. This type of bleeding is more common in individuals who experience more bouts of constipation than diarrhea. As the disease progresses, the frequency of rectal bleeding may increase.
Bleeding in the lower digestive passage above the rectum can also affect the color of the stool. Pay attention to any black, tar-like stools, as they may indicate bleeding higher in the colon. On the other hand, bleeding lower in the colon and from the rectum often results in bright red blood.
Abdominal Discomfort: A Common Symptom of Colon Cancer
Abdominal discomfort is frequently reported by individuals diagnosed with colon cancer. This pain can occur regularly and persistently. Colon cancer can result in sensations of excessive fullness and bloating, even when one has not consumed a meal. In addition, pelvic pain, stomach cramps, and the development of gas and belching can also be experienced. It is important to note that these symptoms are not unique to colon cancer and are often associated with other conditions like gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), and frequent indigestion. Consequently, misdiagnosis is a common occurrence.
