title: Seasonal variation in the month of birth in patients with skin cancer.
abstract: BACKGROUND
  Month of birth influences the risk of developing several diseases. We investigated the influence of date of birth on melanoma skin cancer (MSC) and non-melanoma skin cancer (NMSC) incidence.
  
  
  METHODS
  Enhanced cancer registry data were analysed including 1751 MSC and 15 200 NMSC.
  
  
  RESULTS
  People born in February to April showed significantly elevated risks of NMSC compared with those born in summertime.
  
  
  CONCLUSIONS
  We demonstrated seasonality by date of birth for skin cancer incidence. Neonatal UV exposure may explain this finding.
