The tragic case of a young Taiwanese doctor who succumbed to liver cancer has sent shockwaves through the medical community, serving as a stark reminder of the limitations of standard blood tests. Dr. Liao Yongxiang, a physician at National Taiwan University Hospital, was diagnosed with terminal liver cancer at just 38 years old, despite undergoing regular health checks. His story, recently shared on the Taiwanese health program “57 Health Class,” underscores a vital lesson for the public: normal liver enzyme levels do not always equate to a healthy liver.
A Missed Step in Routine Care
Dr. Liao, a known hepatitis B carrier, rigorously monitored his health through regular blood tests to track his liver enzyme levels. For years, his results consistently returned within the normal range, offering him a false sense of security. However, he inadvertently skipped a crucial diagnostic step—abdominal ultrasounds. By the time symptoms manifested, a 10-centimeter tumor had already developed in his liver. He battled the disease for seven years before passing away, a tragedy that experts say might have been prevented with more comprehensive screening.
Why Blood Tests Are Not Enough
Dr. Huang Xuan, a critical care specialist, emphasized during the broadcast that relying solely on blood tests to measure liver function is a common pitfall. The liver is a resilient organ; it can function normally even when significant damage has occurred. Dr. Huang explained that liver enzyme levels may remain stable in several scenarios, including:
- Post-Inflammation Recovery: Following acute or chronic hepatitis flare-ups.
- End-Stage Failure: When the liver has shrunk and hardened to a point where few cells remain to release enzymes.
- Tumor Presence: Tumors can grow without significantly raising liver enzyme levels in the blood.
Consequently, medical professionals advocate for a dual approach. High-risk individuals, particularly hepatitis B or C carriers, should undergo an abdominal ultrasound alongside blood work. While the liver is located in the upper right abdomen and protected by the rib cage, making it difficult to palpate manually, an ultrasound can reveal physical abnormalities, such as tumors or cirrhosis, long before they affect blood markers.
Recognizing the Silent Warning Signs
The program also highlighted the elusive nature of liver cancer symptoms. Dr. Xiao Dunren, a gastroenterologist, noted that many patients mistake early symptoms for common digestive issues. Advanced cases often present as persistent abdominal pain that does not respond to standard treatments. In some instances, the liver becomes enlarged and hard enough to be felt below the rib cage, signaling the presence of large tumors.
Beyond abdominal pain, dermatological signs can also serve as red flags. Experts warn that chronic skin conditions, such as persistent itching, dermographism (skin writing), or dermatomyositis, may sometimes indicate underlying malignancies. These skin issues arise because the liver’s compromised function affects the body’s immune response and metabolic processes.
Protecting Liver Health
Maintaining liver health requires more than just regular screening; it demands lifestyle adjustments, especially as the organ ages. While the liver is the only internal organ capable of significant regeneration—able to regrow from a third of its original size—its efficiency naturally declines. The organ’s functional peak is generally around age 60. By age 65, liver volume and blood flow decrease significantly, making it more susceptible to damage.
Doctors recommend avoiding four major habits that accelerate liver damage: excessive alcohol consumption, irregular sleep patterns, high-fat diets, and the misuse of unverified supplements or traditional remedies. By combining proactive screening—specifically adding ultrasounds to routine blood work—with a disciplined lifestyle, individuals can better safeguard themselves against the “silent killer” that is liver cancer.
