Risk Factors for Benign Moles

  • Moles can appear at any age
  • Those that are acquired between 2-10 years old are more prominent and persistent, and those that appear later tend to be following sun exposure
  • Light skinned people tend to have more moles than dark skinned people
  • Eye colour is not a risk factor for developing moles
  • People who have many moles tend to have a family history of moles as well
  • Immunosuppressive treatment leads to an increase in benign naevi, and new naevi may also occur after using BRAF inhibitors such as vemurafenib
