[Risk factors associated with etiopathogenesis of non-melanoma skin cancer in Valencia]. / Factores de riesgo asociado a la etiopatogenia del cáncer cutáneo no melanona en Valencia.

A series of personal, occupational and sociocultural characteristics have been described in patients with non-melanoma skin cancer (NMSC). A case-control retrospective study was undertaken to determine these characteristics in patients with NMSC treated in the La Fe University Hospital (Valencia, Spain) between October 1992 and June 1993. NMSC is seen in elderly individuals, the risk being greater among males than in females. A light complexion clearly increased risk, as did a tendency to sunburn easily. Open-air occupational activities were in turn related to an increased risk of developing NMSC. A significant rise in risk was also observed as age-adjusted occupational exposure to sunlight increased.
