What actually builds your skin cancer diagnostic skills over time?

Most GPs see suspicious skin lesions every day. The harder part is deciding, with confidence, which ones need action, which can be monitored, and which are safe to leave alone.  

In this episode of Life by a Thousand Cuts, A/Prof Tony Dicker and A/Prof John Pyne unpack what genuinely builds diagnostic accuracy in day-to-day practice. The conversation covers:

Why volume matters

Not in a rushed, high-throughput sense, but in repeated, deliberate exposure. Over time, pattern recognition sharpens, and subtle lesions become easier to spot.

Why your role matters

A/Prof Dicker and A/Prof Pyne make a clear distinction between being the “diagnostic brain” versus trying to do everything. High-performing clinics are often structured so the GP focuses on assessment and decision-making, with systems and staff supporting everything around it.

How you can measure what you're doing

They point to simple but underused markers of performance, like your ratio of melanoma in situ to invasive melanoma, and the Breslow thickness of lesions you detect. These are practical ways to reflect on whether you are picking things up early enough.

Why tools only help if they build on experience

Dermoscopy, and later confocal microscopy, are framed as extensions of clinical thinking, not shortcuts. Each adds another layer, but none replace the need for solid fundamentals.

This is a grounded discussion about how diagnostic skill actually develops over time. Listen to the full episode below.
