INTRODUCTION: In order to study the relationship between cancer and industrialization the cancer mortality in the an urban area (Baixada Santista, Brazil), an important industrial-harbour complex, two distinct groups: industrialized and non-industrialized, is analyzed. METHODS: A total of 8,546 cancer death registers (according to ICD-9) in males over 10 years old, resident in the that area, were obtained from "Fundação Sistema Estadual de Análise de Dados (SEADE)", during the period 1980-1993. The average mortality rates, standardized on the basis of the to 1960 world population for the area studied, and their strata: Stratum I (inside the industrial area - Santos, S. Vicente, Cubatão and Guarujá) and Stratum II (outside the industrial area - Praia Grande, Mongaguá, Itanhaém and Peruíbe) and the ratios among these rates were calculated adopting the 95% confidence interval. RESULTS: The annual average mortality rate was high, 197.9/100,000 and there was a statistically significant difference between the mortality rates observed in Stratum I and those in Stratum II, 209.2 and 146.7/100,000, respectively, with a ratio of 1.42 (CI 1.36 - 1.51). CONCLUSIONS: It seems that environmental and occupational exposure to carcinogenic chemical agents, related to the productive process in the industrial complex, is a significant factor in mortality due to cancer.
