What Causes Moles?
6. Geographical Statistics
In the United States, acquired moles are so common that some experts do not consider it as an abnormality or defect. Although common, it represents an abnormal proliferation of cells. Most fair-skinned individuals will have at least several moles. It also occurs in dark-skinned individuals but at a lower prevalence.
Distribution differences of moles have also been observed with moles occurring more on the trunk in light skin, while in darker skin, moles tend to occur in the peripheral body parts. Globally, the prevalence of moles are similar to the United States. Individuals in Northern Europe such as Belgium, the Netherlands, and the United Kingdom have been observed to have large moles (equal or more than 1 centimeter in diameter) and have a large number of moles (more than 50).
