A study found evidence that an epidemic of malignant melanoma might be due in part to a growing tendency to identify and treat benign lesions as malignant cancers.
....“Squamous and basal cell carcinomas are no doubt caused by sunlight,” he said, “and those increases are concentrated on the face and neck.” But the diagnoses of melanoma in the registry were mostly on the back, trunk and limbs, areas not consistently exposed to the sun. This means that exposure to sunlight cannot explain the increased number of lesions reported as malignant, he said."
