Abstract: BACKGROUND: Melanoma overdiagnosis occurs when melanomas, not destined to cause morbidity or death in a patient's lifetime, are identified and treated. OBJECTIVE: This study considers the causes and magnitude of melanoma overdiagnosis in Australia. We also speculate about a possible benefit of overdiagnosis in Australia; namely, a reduction in excess deaths in the geographical areas where melanoma is diagnosed most frequently. DISCUSSION: Overdiagnosis can arguably be mitigated by factors that reduce the number of lesions treated for each melanoma identified. Data from the Australian Cancer Atlas show that there is a reduction in excess deaths from melanoma in geographical areas where diagnostic rates are higher (Pearson correlation coefficient r=-0.5978, 95% CI: -0.6243 to -0.5699, P<0.0001); this being the strongest inverse correlation observed among the 20 cancer types in the Atlas. Is early diagnosis of actual life-threatening melanomas in these geographical regions impacting survival? Further research is planned.
