Introduction: Non-melanoma skin cancer (NMSC) is the most common among all malignancies. Objective: To describe trends in NMSC mortality rates in Brazil and its macroregions from 2001 to 2018. Method: Adjusted mortality rates stratified by sex were estimated and presented per 100,000 person-years. An autoregressive analysis was implemented to assess temporal trends, annual percent change (APC) and 95% Confidence Intervals (95% CI). Results: There were 27,550 NMSC deaths in Brazil with higher frequency in males (58.1%) and among individuals aged ≥70 years (64.3%). The overall rates were 2.25 (males) and 1.22 (females) per 100,000 person-years. The trends followed an upward direction in Brazil for males (APC: 2.91%; 95% CI: 1.96%; 3.86%) and females (APC: 3.51%; 95% CI: 2.68%; 4.34%). The same occurred in the North Region, in males (APC: 9.75%; 95% CI: 7.68%; 11.86%) and in females (APC: 10.38; 95% CI: 5.77%; 15.21%), as well as in Northeast Region, in males (APC: 9.98%; 95% CI: 5.59%; 14.57%) and in females (APC: 8.34%; 95% CI: 3.29%; 13.64%). Conclusion: NMSC deaths are not rare in Brazil. Upward mortality trends were observed for the whole country and in the North and Northeast regions, which are the closest to the Equator line and also the least developed socioeconomically. A synergism between different types of inequalities and environmental exposure in these macroregions may be promoting an increase in the number of NMSC deaths, a type of cancer which is considered completely preventable.
