Objective: To analyze the temporal evolution of incidence and trends of skin cancer, either melanoma and nonmelanoma lesions, in the city of Goiania during the period from 1998 to 2008. Methods: From January 1988 to December 2008, all malignant skin tumours of the city of Goiania (Brazil), registered by the Population Based Cancer Register of Goiania were accessed. The cases were stratified according to gender, age, morphology and anatomical site. The proportions, crude coefficients and incidence rates were calculated using the SPSS version 18 software, while Poison's regression model was obtained by Joinpoint software. Results: Twenty six thousand nine hundred and eighty-eight registers of skin cancer were found, 19,961 basal cell carcinomas (BCC), 6,156 squamous cell carcinomas (SCC) and 871 cutaneous melanomas (CM). Histological confirmation was performed in more than 98% of the cases. A significant trend of increasing incidence associated to age was observed in men with SCC (APC=6.6%) and CM (APC=9.8%). The same trend was identified for women with CM (APC=7.7%). A rising incidence related to age was found. Nonmelanomas skin tumours occurred more often on face, while the trunk was more common for melanomas. Conclusions: The incidence of BCC was stable for both genders in Goiania during the study period. In the other hand, it was observed an increasing incidence for CM in men and women, and SCC showed a raise in incidence only for males. The age above 50s is a risk factor for increasing incidence of skin cancer. The trunk and face were the most common sites of either SCC and BCC, while cutaneous melanomas were more often on the trunk and limbs. Prevention through a complete physical exam is the best action for early detection of skin lesions; as well information regarding the risks of excess chronic sun exposition is the best primary prevention method.
