Non-melanoma skin cancers (NMSC) represent the most frequently diagnosed malignancies in developed countries, with a globally rising incidence. This review article summarizes the main types of NMSC - basal cell carcinoma, squamous cell carcinoma, and Merkel cell carcinoma - with a focus on their epidemiology, risk factors, diagnosis, treatment, and preventive strategies. Particular attention is given to primary and secondary prevention, including current research on chemoprevention agents such as nicotinamide, vitamin D, and celecoxib. The article also discusses the importance of early detection, surgical and non-surgical treatment approaches, and emerging trends in systemic therapy for advanced or recurrent disease. It highlights the growing need for public education and a multidisciplinary approach to improve outcomes in the management and prevention of these common conditions.

Keywords: non-melanoma skin cancer, basal cell carcinoma, squamous cell carcinoma, Merkel cell carcinoma.
