Of 171 participants (surfers 116, swimmers 55) significantly more surfers were identified with a skin cancer of any type versus swimmers (50% vs 27.3%; OR 2.67; P <.005) with most the common being PSC (44.7% vs 11.3%, P < 0.05) followed by basal cell carcinoma (BCC) (24.2% vs 7.6%, P < 0.05). There was a total of 7 MSC (5.2% vs 1.8%, respectively, P > 0.05). Rates per 100,000 of NMSC and MSC (respectively) were BCC (27,568 vs 18,181), squamous cell carcinoma (SCC) in situ (20,690 vs 40,00), SCC (9,482 vs 7,272) and MSC (5,172 vs 1,818).
