Doctors could soon use AI-based systems to detect skin cancers early

At the 14th International Conference on Image Analysis and Recognition, a team of researchers presented an AI-based system, which can detect skin cancer earlier than current methods of diagnosis.

The new method, developed by researchers from the University of Waterloo, uses a machine-learning software that analyses images of skin lesions, such as moles, and looks for biomarkers of melanoma, a form of skin cancer, which can also prove deadly if detected too late.

It then follows an appearance-based approach to match these lesions with tens of thousands of skin images.

The system targets strongest indicators of cancer and looks for changes in concentration and distribution of eumelanin –a chemical which defines skin colour– and hemoglobin levels.

Finally, it combines that data with consistent, quantitative information and hands out a report, detailing characteristic information of the abrasions to help doctors decide whether a patient should undergo expensive biopsies to diagnose the disease.

"This could be a very powerful tool for skin cancer clinical decision support," said Alexander Wong, a professor who worked on the study.
