About Woo Cheal Cho

Pathology is a uniquely rigorous field. Unlike many other medical specialties, where a wide differential diagnosis is part of the process, pathologists are expected to provide definitive answers. That challenge – and responsibility – is what drew me to the specialty. Because of the nature of the work, attention to detail and a meticulous, even obsessive mindset are essential qualities in a great pathologist.

One of the most important lessons I learned early is that diagnostic skill is not measured by a CV, the number of publications, or national presentations. While academic contributions are valuable, they do not necessarily reflect diagnostic thoroughness. I emphasize this to my trainees: what matters most is the quality and integrity of the work at the microscope.

I encourage trainees to approach slide review deliberately and thoroughly. The ability to make a diagnosis at low power may look impressive, but it often comes at the cost of missing subtle, yet critical, findings at higher magnification. Pathology is not a speed competition – accuracy and completeness always come first.

Another principle I stress is the importance of clear, professional, and error-free pathology reports. Our reports are not only read by clinicians; patients and families may also see them. Reports must communicate essential diagnostic information, use precise grammar and terminology, and reflect the seriousness of our role.

I also teach trainees to approach learning with objectivity and openness. Seniority should not determine the weight of an opinion. Instead, I encourage them to learn from the strengths of each attending while developing their own diagnostic style and critical thinking.

The same caution applies to the literature. A published article or textbook is not automatically infallible. Errors can persist if repeated uncritically. I urge trainees to approach sources with a questioning mindset – verify claims, think independently, and rely on evidence-based reasoning alongside personal diagnostic experience.

These are the principles I aim to instill in those I mentor: precision, professionalism, intellectual humility, and independent critical thinking. I believe these values are what ultimately define excellence in pathology.
