Colon cancer, also known as colorectal cancer, is a type of cancer that begins in the large intestine. It typically affects older adults, but it can happen at any age. Colon cancer often begins as small, benign clumps of cells called polyps that form on the inside of the colon. Over time, these polyps can become colon cancers. Early detection of colon cancer can significantly improve the prognosis, as it is more manageable when identified in its initial stages. This article aims to highlight six early symptoms of colon cancer to help readers identify possible signs and seek medical advice promptly.
Changes in Bowel Movements
One of the most common early symptoms of colon cancer is a change in bowel movements. This can include diarrhea, constipation, or a change in the consistency of the stool that lasts longer than four weeks. While occasional changes in bowel habits are common and not usually a cause for concern, persistent changes could be a sign of colon cancer and should be evaluated by a healthcare professional.
Blood in Stool or Rectal Bleeding
Blood in the stool or rectal bleeding is another early symptom of colon cancer. The blood may appear bright red or very dark. Sometimes, the blood can be present but not visible to the naked eye, a condition known as occult bleeding. If you notice any blood after a bowel movement, it's important to talk to your doctor as soon as possible.
Persistent Abdominal Discomfort
Abdominal discomfort, such as cramps, gas, or pain, that persists for an extended period, can also be a sign of colon cancer. This discomfort can be accompanied by a feeling of fullness or bloating. While these symptoms can be caused by a variety of conditions, it's important to seek medical advice if they continue longer than expected.
Weakness or Fatigue
Unexplained weakness or fatigue can be a symptom of colon cancer. This can be due to the cancer cells using up the body's energy or from blood loss if there is bleeding. Fatigue that doesn't improve with rest should not be ignored, as it could be a sign of an underlying health issue, including colon cancer.
Unexplained Weight Loss
Weight loss without trying can be a symptom of many types of cancer, including colon cancer. If you've lost weight and don't know why, it's important to discuss this with your doctor. Weight loss can occur because cancer cells use up more of the body's energy, or it could be due to changes in the way the body absorbs nutrients from food.
Feeling That the Bowel Doesn't Empty Completely
A sensation that the bowel doesn't empty completely after a bowel movement can also be a symptom of colon cancer. This feeling can persist even after having a bowel movement and can be accompanied by a frequent urge to have a bowel movement.
