A review of 114 studies finds skin cancer imaging tools are improving, but cost and access still limit their reach in under-resourced settings.
A single handheld lens still outperforms most newer technologies where it matters most: in the clinic, in the hands of a practitioner, in a community that cannot wait for a machine.
A review published in the Journal of Investigative Dermatology examined 114 studies evaluating eleven imaging modalities used to detect melanoma. The analysis, led by Boostani et al., found that dermoscopy remains the diagnostic standard for skin cancer detection. Reflective confocal microscopy came close — approaching the precision of histopathology, the tissue-examination method long considered the gold standard — but its availability remains narrow.
Artificial intelligence tools and other advanced imaging options exist and are improving, the review noted. The gap is not in the science. Cost, reimbursement infrastructure, and the practical difficulty of integrating new technologies into everyday clinical workflows continue to slow adoption, according to the authors. Those barriers fall heaviest in underserved and resource-limited regions.
Why this reaches the albinism community directly
People with albinism carry a significantly elevated risk of skin cancer, particularly squamous cell carcinoma, due to reduced melanin and a lifetime of sun exposure. Early, accurate detection is not a preference — it is a clinical necessity. For communities in Sub-Saharan Africa and other low-resource settings where that risk is highest and dermatology infrastructure is thinnest, the findings in this review describe a reality many already live with.
Dermoscopy's continued dominance is, in one reading, good news: the tool is relatively affordable, portable, and teachable. A specialist is not always required. Community health workers and nurses can be trained to use it. That accessibility matters when specialist dermatology appointments are weeks away or unreachable entirely.
The harder finding is that better tools exist and are not arriving where they are needed. Reflective confocal microscopy's near-histopathological accuracy could change outcomes for high-risk patients — but only if the economics and systems required to deploy it can be built in the places that need it most.
The review did not propose solutions. It mapped a distance.
