5 Overlooked Warning Signs of Colon Cancer: What You Need to Know

Colon cancer, also known as colorectal cancer, originates in the colon or rectum, the final segment of the large intestine. It frequently begins as benign clumps of cells termed polyps, which can develop into cancerous growths over time. While most cases arise spontaneously, factors like family history, obesity, and lifestyle choices can elevate the risk. The majority of diagnoses occur after age 50, and early symptoms tend to be subtle, often resembling common digestive issues or stomach infections. Nevertheless, certain telltale signs warrant attention.

Bowel Habit Alterations

One of the first indicators of colon cancer is a change in bowel habits. These alterations may manifest as:

• Increased frequency of diarrhea or constipation
• Alternating episodes of diarrhea and constipation
• Stools that appear narrower or thinner than usual

These changes may seem insignificant or transient, often attributed to dietary factors, stress, or minor infections. However, persistent bowel changes lasting more than a few days or recurring frequently could signal the presence of a growing tumor disrupting normal bowel function.

Blood in Stool

The presence of blood in stool should always be a cause for concern. This can present as:

• Bright red blood on the surface of the stool or toilet paper
• Dark or black, tarry stools indicating the presence of older blood

In some instances, the bleeding may be microscopic, leading to anemia over time. While blood in the stool can stem from various conditions like hemorrhoids or infections, it's imperative to rule out colon cancer, particularly if it occurs repeatedly or alongside other symptoms.

Abdominal Discomfort or Pain

Persistent abdominal discomfort is another early symptom often overlooked. This may include:

• Cramps or gas pains
• Bloating or a sensation of fullness
• Generalized abdominal pain that doesn't subside

Such discomfort can be mistaken for indigestion or other minor digestive issues. However, if the pain is ongoing and unrelated to dietary or lifestyle changes, it could indicate a tumor causing irritation or blockage in the colon.

Fatigue and Weakness

Unexplained and persistent fatigue or weakness can be a subtle sign of colon cancer, especially when accompanied by other symptoms. This occurs because slow, undetected bleeding in the colon can result in iron deficiency anemia. The reduced number of red blood cells impairs oxygen transport, leading to fatigue, shortness of breath, and weakness. Although these symptoms may be dismissed as stress-related or due to lack of sleep, they warrant medical evaluation.

Unexplained Weight Loss

Losing weight unintentionally is a common symptom associated with many cancers, including colon cancer. When the body is combating cancer, the immune system remains in a heightened state, and tumors can interfere with digestion and appetite. Significant weight loss without changes in diet or exercise necessitates a medical consultation. While this symptom often manifests later, it can occasionally serve as an early warning sign.
