Breast cancer mortality information contained in the available statistics derived from the Spanish death certificates has been reviewed. Mortality from breast neoplasms was grouped into three five-year periods: 1903-1907, 1931-1935 and 1975-1979. Age-adjusted rates were estimated for every province (n = 49) in each period, and confidence intervals for the standardized mortality ratios and adjusted rates were calculated. Results are presented with maps of Spain that illustrate provincial contrasts in each period. Secular breast cancer mortality trends in the provinces are discussed in comparison with those of other countries. Furthermore, values are compared with the geographical distribution of risk factors, the aim being to formulate hypothesis explaining the observed contrasts and suggesting some future research lines.
我们对西班牙死亡证明中现有统计数据所含的乳腺癌死亡率信息进行了审查。乳腺肿瘤死亡率被分为三个五年期：1903 - 1907年、1931 - 1935年和1975 - 1979年。对每个时期的每个省份（共49个）估算了年龄调整率，并计算了标准化死亡率比值和调整率的置信区间。结果通过西班牙地图呈现，展示了各时期省份之间的差异。文中还讨论了各省份乳腺癌死亡率的长期趋势，并与其他国家进行了比较。此外，将这些数据与风险因素的地理分布进行了比较，目的是提出假设来解释所观察到的差异，并提出一些未来的研究方向。
