A recent news story regarding a patient diagnosed with late-stage kidney cancer after a decade of normal checkups has triggered public anxiety. In response, leading medical experts gathered to discuss the true value of a health checkup and the scientific path for cancer screening. They emphasized that while checkups are crucial for disease prevention, understanding their limitations is equally important.
Understanding the Value and Limitations
Wang Zhanshan, Secretary-General of the Chinese Society of Health Management, clarified that the core purpose of a health checkup is to maintain, promote, and manage health. However, a “normal” report does not equate to “zero health risks.” Checkups are limited by factors such as age, genetics, and lifestyle. Furthermore, routine exams may not cover deep diagnostic checks. Wang noted that cancer is often a disease of aging, and regular screening is essential for early detection.

The Science Behind Cancer Screening
Why can’t a single checkup detect all cancers? Zhang Qingyun, former director of the Laboratory Department at Peking University Cancer Hospital, explained that ideal tumor markers with 100% sensitivity do not exist. For instance, the sensitivity of Alpha-fetoprotein (AFP) is only about 60-70%. Currently, there is no specific tumor marker for kidney cancer. Therefore, experts urge the public to view test results scientifically. “Cancer is not sudden in onset, but suddenly discovered,” Wang added. Checkups serve as a risk warning; if abnormalities are found, further clinical diagnosis is necessary. According to the World Health Organization , early detection significantly improves cancer survival rates.
Legal Perspectives on Medical Responsibility
Addressing concerns about “fake checkups,” lawyer Jiang Hai stated that the possibility is low for reputable institutions due to strict regulations. He distinguished between “technical limitations” and “institutional negligence.” If a condition was objectively undetectable with current technology, it does not constitute fault. However, if negligence led to a missed diagnosis, the institution would be held liable.
Expert Advice: Personalization is Key
How can patients improve their outcomes? The experts unanimously agreed on personalized screening plans.
- Age and Gender: Men over 50 should screen for prostate cancer, while women need breast cancer screening.
- Family History: Those with a family history of conditions like colon polyps require focused screening.
- Lifestyle: Individuals with poor habits should screen for digestive system tumors.
Pang Ran, a specialist from Guang’anmen Hospital, advised patients to monitor dynamic changes in indicators. For example, even if PSA levels are normal, a continuous rise warrants attention. Ultimately, a health checkup is an irreplaceable part of the “Healthy China 2030” initiative, shifting the focus from treatment to prevention.
