Experts teach you 5 points to identify the early symptoms of colon cancer

As a gastroenterologist, I've seen countless cases where poor lifestyle choices have led to significant health issues. Jack Thompson's case stood out. A software engineer in his thirties, his body had begun to show the wear of a high-fat diet and a sedentary job. I remember how he tried to mask his anxiety with humor during our first meeting, but his eyes flickered with genuine fear when I mentioned the need for a colonoscopy.

"Doctor, is it serious?" he asked, with a cautious tremor in his voice. His expression and tone wavered then. The early symptoms of colon cancer are often subtle—just some irregular bowel habits and mild abdominal pain. But Jack's instincts told him it wasn't just his unhealthy lifestyle at play, but perhaps a harbinger of something more severe. His premonition was not misplaced; silence fell upon us as the test results came in.

The confirmation of Jack's early-stage colon cancer was a silver lining, albeit one heavily clouded by anxiety. I watched as his facial muscles toggled between tension and release, processing the gravity of his diagnosis. I understood that Jack's life was about to be turned upside down by this news. He nodded silently, a flicker of resolve passing through his eyes, perhaps ready to combat the forthcoming storm of illness or to change those long-ingrained unhealthy habits.

"What do I do now?" he finally asked, vulnerability undisguised in his voice.

We discussed his treatment plan in detail—surgery, chemotherapy, and lifestyle adjustments for the aftermath. Jack listened intently, nodding occasionally. His case reminded me that a doctor's duty is not only to treat the illness but also to educate and assist patients in making better life choices, and preventing disease before it takes hold.

Colon Cancer Medical Definition

Colon cancer, also known as colorectal cancer, primarily refers to malignant tumors originating from the inner lining of the colon. According to the National Cancer Institute (NCI), colon cancer is the third most common type of cancer in the United States, with an estimated 151,030 new cases expected in 2022. The colon is an integral part of the digestive system, involved in processing waste material. Abnormal growth of colon cells can lead to polyps that may develop into cancer.

Early Symptoms of Colon Cancer

Colon cancer may not exhibit symptoms in the early stages, however, some common signs include:

1. Persistent diarrhea or constipation

2. Changes in stool shape

3. Bloody stools

4. Unexplained weight loss

5. Chronic fatigue.

 According to data provided by the American Cancer Society, about 40% of colon cancer patients exhibit symptoms by the time they receive a diagnosis."

The Impact of Colon Cancer

Colon cancer has a profound impact on the physical and mental health of patients. This includes short-term and long-term side effects caused by treatments, such as bowel dysfunction and postoperative complications. Psychologically, patients may experience anxiety, depression, and emotional swings. Global data on cancer research indicates that the overall five-year survival rate for colon cancer is around 63%.

Common Causes of Colon Cancer

The development of colon cancer is associated with multiple factors, including genetic predisposition, dietary habits (particularly high in red meat and low in fiber), lifestyle choices (such as lack of physical activity), smoking, alcohol abuse, and obesity. Environmental factors and personal history, such as a history of inflammatory bowel disease, also contribute to a higher risk of colon cancer. Statistics indicate that approximately 5% to 10% of colon cancer cases are related to genetics.
