Colon Cancer: Don't Ignore These 5 Early Warning Signs

Colon cancer, also known as colorectal cancer, develops in the colon or rectum. It often begins as noncancerous polyps that can become cancerous over time. While most cases occur randomly, family history, obesity, and lifestyle can increase risk. Many early symptoms are mild and mistaken for digestive issues. However, certain warning signs should not be ignored.

Changes in Bowel Habits

One of the earliest signs of colon cancer is a noticeable change in bowel habits, including:

• More frequent diarrhea or constipation
• Alternating between diarrhea and constipation
• Stools that are narrower or thinner than usual

These changes may seem minor and are often attributed to diet, stress, or infections. However, if these bowel changes persist for more than a few days or recur, it could be a warning sign. Persistent changes suggest a growing tumor disrupting normal bowel movements.

Blood in Stool

Blood in stool should always be evaluated, regardless of whether colon cancer is suspected. It can appear as:

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

Sometimes, the bleeding is not visible but can cause anemia over time. While blood in the stool can be caused by conditions like hemorrhoids or infections, it is crucial to rule out colon cancer, especially if it happens repeatedly or with other symptoms.

Abdominal Discomfort or Pain

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

• Cramps or gas pains
• Bloating or a feeling of fullness
• General belly pain that does not go away

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

Fatigue and Weakness

Feeling unusually tired or weak without a clear reason can be a subtle sign of colon cancer, particularly when accompanied by other symptoms. Slow, unnoticed bleeding in the colon can lead to iron deficiency anemia. With fewer red blood cells, the body cannot carry enough oxygen, resulting in fatigue, shortness of breath, and weakness. While these symptoms may be dismissed as stress or lack of sleep, they should be investigated.

Unexplained Weight Loss

Losing weight without trying is a common symptom in most cancers, including colon cancer. When the body is fighting cancer, the immune system is constantly on overdrive, and tumors can affect digestion and appetite. If you notice significant weight loss without changes in diet or exercise, consulting a doctor is important. This symptom often appears later but can sometimes be an early warning sign.
