"Epidemic" of Malignant Melanoma: True Increase or Better Detection?

Comparing alternative methods of measuring skin color and damage

“…Longitudinal studies could also evaluate the predictive validity of some of these measures. Skin cancer rates and exposure behaviors such as indoor tanning are rising, while protective behaviors such as sunscreen use remain steady (Feldman et al , 2004; Lamberg, 2002; NCI, 2007; Robinson et al , 1997). Adequate measurement of skin color and damage is important for surveillance in prevention and intervention efforts.…”

Melanoma epidemic: True or false?

“…An earlier diagnosis as a result of better surveillance and greater awareness by the public has been offered as an explanation for this discrepancy. Although this explanation is attractive, in the absence of large‐scale randomized trials to evaluate the benefits of early detection campaigns in the general population, it cannot be concluded that it is correct and biases cannot be excluded 11,12,16 . In addition, several authors have suggested, as an alternative explanation to the increased reporting of melanoma with a better prognosis, that surveillance may have led to increased diagnosis of histologically worrying but biologically benign lesions 4,12,16 …”

Malignant melanoma

“…This controversial question has generated much discussion over the last decade. Some argue it is an apparent phenomenon explained by improved screening efforts, earlier detection and changes in diagnostic criteria (Lamberg, 2002). That said, this does not explain the increase in melanoma of all Breslow thickness levels, increased rates of metastatic disease, and a rise in melanoma-related mortality (Menzies et al., 2018).…”
