Alternative diagnostic labels for melanoma in-situ: a randomised online experiment

Half of the participants in this randomized online experiment of 1655 Australian adults would prefer to not have a wide local excision after a completely excised low-risk melanocytic lesion, if offered this option. Using the term “low risk melanocytic neoplasm” instead of “melanoma in-situ” reduced anxiety and the proportion choosing a wide local excision. Across all label groups, most participants preferred to attend routine 6-monthly clinic visits for follow-up, likely reflecting the high prevalence of this in the Australian context.
