5 Common Colon Cancer Signs People Often Overlook

What is colon cancer?

Colon cancer, also known as colorectal cancer, is a type of cancer that begins in the large intestine (colon), or rectum. It usually begins as small, noncancerous clumps of cells called polyps that form on the inner lining of the colon. Over time, some of these polyps can become cancerous. The cancer can then grow into the wall of the colon and, if left untreated, spread to nearby lymph nodes and other parts of the body, a process called metastasis.

Five common signs of colon cancer!

Colon cancer, also known as colorectal cancer, is the leading cause of cancer deaths worldwide. According to the World Health Organization (WHO), more than 1.9 million new cases of colorectal cancer were reported in 2020, and it claimed 930,000 lives worldwide. The agency also predicts that by 2040, new cases of colon cancer will increase to 3.2 million (an increase of 63%), and deaths will reach 1.6 million per year (an increase of 73%). Therefore, early detection is crucial to improving outcomes. However, many early symptoms are subtle, and are more likely to be missed or mistaken for other, relatively less worrisome health concerns. This delays diagnosis, which negatively affects treatment plans and outcomes.

Here are five symptoms of colon cancer that are often overlooked.

1- Changes in bowel habits

Any changes in the bowel habits should not be easily dismissed. Having persistent changes in bowel pattern, such as diarrhea, constipation, or a feeling that the bowel isn’t completely empty, is an early symptom of colon cancer. People often attribute these changes to diet or stress. However, if diarrhea, constipation, or narrowing of the stool lingers for more than a week, you should consult a doctor.

2- Blood in the stool

An early sign of colon cancer is blood in the stool. If you notice bright red or dark blood in the stool, you need immediate medical help. These signs are often dismissed as hemorrhoids or minor gastrointestinal issues. Though such concerns, too, can lead to blood in stool, rectal bleeding should never be ignored.

According to WHO, blood in the stool, either bright red or dark and tar-like, is a common symptom of colon cancer. Most colon cancer patients complain about rectal bleeding. Early investigation through a colonoscopy can clarify the cause and catch issues before they progress.

3- Abdominal discomfort

Frequent abdominal cramps, pain, or bloating that does not go away is a red flag. This could be an indication of colon cancer. When this abdominal pain persists, even after administering remedies, it’s concerning. Many mistake this for irritable bowel syndrome or gas. If you have persistent abdominal pain and have other symptoms, you should consult a doctor and investigate the cause.

4- Unexplained weight loss

Remember, losing weight without trying is never a good sign. Sudden, unintentional weight loss may be a warning sign of cancer, including colon cancer. If you lose 10 pounds or more without changes in diet or exercise, you should talk to your doctor. This sign is often overlooked, and people tend to think it’s a positive change. If this symptom is combined with other colon cancer symptoms, it’s worth investigating.

5- Chronic fatigue

Feeling tired all the time, even after rest, is a red flag. Fatigue is another overlooked symptom, and people tend to attribute it to work or stress. Colon cancer can cause internal bleeding, leading to anemia and reduced energy levels. Studies have consistently shown that colon cancer patients have reported fatigue as an early symptom. It is easy to overlook this symptom for busy lifestyles. But if this sign is paired with other symptoms, it demands attention.

age
family history
personal history

Consult a doctor

If you experience these signs, especially when 2 or more, it is important to schedule a visit to your doctor’s to investigate its cause. When it comes to cancer, early detection is very crucial, for both the treatment options and outcomes.
