Colon cancer often develops silently, but certain symptoms can signal that something isn’t right. Recognizing these early warning signs may lead to earlier detection and more effective treatment.
Changes in Bowel Habits That Last
One of the most common early indicators of colon cancer is a persistent change in bowel movements. This can include diarrhea, constipation, or a feeling that your bowel doesn’t empty completely. If these changes last longer than a few days without explanation, it's important not to ignore them. While occasional irregularity is normal, long-term changes may suggest that something is disrupting the digestive process. Early screening and medical attention can help determine whether a deeper issue is present.
Unexplained Bleeding or Blood in Stool
Seeing blood in your stool or experiencing rectal bleeding can be alarming—and for good reason. These symptoms are often associated with hemorrhoids or other minor issues, but they can also point to colon cancer, especially when the bleeding is persistent or accompanied by dark, tarry stools. It’s crucial to take this symptom seriously, particularly for individuals over the age of 45 or those with a family history of colorectal conditions. Prompt testing such as a colonoscopy can help identify the cause and lead to timely intervention.
Ongoing Fatigue and Unexplained Weight Loss
Colon cancer can cause internal bleeding that leads to anemia, resulting in chronic fatigue or weakness. When paired with unintended weight loss and reduced appetite, these symptoms should not be dismissed. Feeling constantly tired despite getting enough rest, or losing weight without trying, may be signs that your body is under stress from a growing tumor. Listening to your body and discussing such symptoms with a healthcare provider could lead to early diagnosis and potentially life-saving treatment.
