What makes this symptom deceptive is that it often mimics common gastrointestinal issues such as IBS or food intolerances. However, colon cancer-related cramps are typically more persistent, more painful, and not easily relieved by diet changes or over-the-counter remedies.
People often chalk these symptoms up to stress or lifestyle factors, thereby delaying critical screening that could identify colon cancer in its early stages.
5. Feeling of Incomplete Bowel Movements: Always Needing to Go
A lesser-known but significant symptom of colon cancer is tenesmus—the persistent sensation that one needs to have a bowel movement, even if the bowel is already empty. This feeling is caused by a tumor pressing against the rectal walls, mimicking the sensation of stool presence.
This symptom is particularly troubling because it often leads to multiple, unproductive trips to the bathroom, creating discomfort and anxiety. It is commonly misdiagnosed as hemorrhoids or minor inflammation, especially when not accompanied by visible blood or pain.
Ignoring this sign can lead to significant delays in diagnosis, allowing the tumor to grow and metastasize before it’s discovered.
