It began at just 32 years old, when Taiwanese cardiologist Dr. Chen Wei-Hua received a life-altering diagnosis—the first of four cancers he would face over the subsequent two decades. In a remarkably candid interview on Taiwan’s Health 2.0 program, the physician chose not to focus solely on his medical treatments. Instead, he delivered a sobering retrospective on the five specific lifestyle habits, formed in childhood and young adulthood, that he believes methodically cultivated a cancer-prone constitution (易癌體質).
What Created the Terrain for Recurring Disease?
Dr. Chen’s story cuts to the heart of an uncomfortable question for many: how does a medical professional, someone who understands the human body intimately, become a repeated target for its most feared disease? His answer lies not in a rare genetic anomaly, but in the accumulation of seemingly mundane daily choices.
1. A Diet Built on Convenience, Not Nourishment
Dr. Chen traced his eating patterns back to childhood, where a preference for processed snacks and sugary beverages took root. This evolved into a diet heavily reliant on street foods and quick meals during his demanding medical career. He directly attributes this chronic intake of high-calorie, low-nutrient, inflammatory foods to laying the groundwork for his recurring health battles. For a food-centric audience, the lesson is unmistakable: what we eat literally composes the soil of our health.
2. The Deadly Silence of the Asian Flush
This finding is particularly urgent for Asian readers. Dr. Chen acknowledged years of regular alcohol consumption despite the immediate facial redness—the Alcohol Flush Reaction—that followed each drink. This flush is a visible sign of a genetic deficiency in the ALDH2 enzyme. Without this enzyme, the body cannot effectively break down alcohol, leading to a toxic buildup of acetaldehyde, a potent carcinogen.
The stark statistic from the program is impossible to ignore: drinkers who experience this flush face a 50 times higher risk of esophageal cancer compared to those who do not flush. What many consider a harmless social quirk emerges as a major red flag.
3. Sacrificing Sleep for Success
The grueling hours of medical training created a permanent state of sleep deprivation. Dr. Chen stressed that a disrupted circadian rhythm severely impairs the body’s natural immune surveillance and cellular repair mechanisms.
4. The Sedentary Trap
Despite his cardiology expertise, Dr. Chen neglected purposeful physical activity for years. The resulting metabolic slowdown and weight gain created an “easy terrain” for cancer cells to thrive.
5. Bottling Up Emotional Stress
The “tough it out” culture led him to suppress enormous amounts of psychological strain. He now advocates for emotional honesty and active stress management as essential pillars of cancer prevention.
The Takeaway for Hong Kong Audiences
Dr. Chen’s journey offers a powerful checklist for evaluating our own environment:
- Assess your alcohol tolerance honestly. If your face flushes after a single drink, your genetic makeup is issuing a clear warning. Abstinence or strict moderation is not prudence—it is prevention.
- Audit your kitchen. Reducing processed sugars and fried foods directly reduces systemic inflammation.
- Treat sleep as medicine. Seven to eight hours of quality rest is foundational to immune function.
A Legacy of Prevention
Dr. Chen Wei-Hua’s story is ultimately one of hope grounded in hard truth. By bravely dissecting his own bad habits, he has transformed his suffering into a vital public health resource. It proves a profound lesson: while our genes may be fixed variables, our daily choices are powerful, modifiable levers for health. His message transcends medical expertise, offering a roadmap for anyone willing to look honestly at their own lifestyle and make changes before a diagnosis forces the issue.
