Doctor Warning: Colon Cancer Is Rising Fast And One Test Can Save Your Life

Health experts are sounding the alarm on a growing global threat. Colorectal cancer, which includes cancers of the colon and rectum, is expected to cause over 3.2 million new cases and 1.6 million deaths every year by 2040. The World Health Organization projects that this will be a 73 percent increase from today’s numbers, making it one of the world’s deadliest and most preventable cancers.

Dr. Emmanuel Aguh, a board-certified family medicine physician in the United States, recently shared insights after reacting to a video of a 31-year-old woman diagnosed with colon cancer. He said that no one expects such a diagnosis at that age, but cases like hers highlight why awareness and proactive screening are so vital. According to him, colon cancer doesn’t have to be a silent killer if people act early and stay informed about their health.

Understanding How Colon Cancer Develops

Colon cancer begins in the colon, which forms the first and longest part of the large intestine. It usually starts as tiny growths known as polyps that can turn cancerous over time. Most people never notice these polyps until they cause symptoms, which is why screening becomes crucial.

Dr. Aguh explained that the main tool for early detection is the colonoscopy, a procedure that allows doctors to examine the colon and remove any suspicious growths before they become dangerous. He noted that colon cancer is one of the few cancers that can be prevented entirely if caught early, but the window for early detection is often missed because people delay or avoid the test.

Medical guidelines recommend that adults begin routine colon cancer screening at age 45. However, those with a family history of colorectal cancer, inflammatory bowel disease, or other risk factors may need to start earlier.

Risk Factors and Warning Signs You Shouldn’t Ignore

Doctors emphasize that while age and genetics are strong risk factors, lifestyle also plays a major role. A diet high in processed meats and low in fiber, lack of physical activity, obesity, excessive alcohol intake, and smoking all increase risk. Dr. Aguh stressed that small lifestyle changes can dramatically reduce one’s chances of developing the disease.

He also advised people to stay alert to potential warning signs. Unexplained fatigue, persistent abdominal pain, sudden changes in bowel habits, blood in stool, or unexplained weight loss could signal that something is wrong. While these symptoms can stem from other causes, ignoring them can allow cancer to progress silently.

Overcoming Fear of Colonoscopy

Dr. Aguh acknowledged that many people feel uneasy about undergoing a colonoscopy. Some fear discomfort or embarrassment, while others simply dread medical procedures. He reassured that the test is performed under sedation, so patients usually sleep through it and wake up with no memory of discomfort. The procedure typically lasts less than an hour, and recovery is quick.

He said that the fear of the test often outweighs the reality. The truth is, colonoscopies save lives. By detecting and removing precancerous polyps, the procedure stops cancer before it starts. Dr. Aguh encouraged people to think of it as a long-term investment in their health, a small, temporary inconvenience that can prevent years of suffering later.

For younger adults, colonoscopy may not be part of routine care unless symptoms or risk factors appear. Still, Dr. Aguh said stories like that of the 31-year-old patient serve as reminders that no age group is entirely immune. If something feels off, medical advice should not be delayed.

Prevention Is Still the Best Protection

Experts consistently point out that colon cancer is one of the few major cancers that can often be prevented through screening and healthy habits. A diet rich in vegetables, fruits, and whole grains supports digestive health, while regular exercise helps maintain a healthy gut and immune system.

Dr. Aguh urged people to discuss screening schedules and family history with their physicians. Those who have close relatives with colon cancer or genetic syndromes such as Lynch syndrome may require more frequent monitoring.

He also reminded that prevention isn’t only about tests, it’s about paying attention to the body’s cues. Changes in digestion, persistent bloating, or pain shouldn’t be brushed aside. Early conversations with doctors can lead to timely tests and treatment, significantly improving survival rates.
