A study is presented about the evolution of the breast cancer mortality in Spain between 1961 and 1980. This has been increasing strongly of several factors: 1) In actual increase of this disease, rising its adjusted death rates by age from 8/100,000 (1961) to 13/100,000 (1980) (increase = 62%); the truncated standardized rates between 35 and 64 years raised from 18/100,000 (1961) to 28/100,000 (1980): there is high correlation between both types of rates. 2) An increase of the female population at breast cancer risk (over 45 yr). A selective and significative rise of mortality from this cancer for the age groups under menopause, especially for the group 30-34 years (160%). The increase of female breast cancer mortality is statistically significant. It is necessary researching the causes of such increase.
一项关于1961年至1980年间西班牙乳腺癌死亡率演变的研究被呈现出来。乳腺癌死亡率因几个因素而显著上升：1）这种疾病的实际发病率增加，其年龄调整死亡率从8/10万（1961年）升至13/10万（1980年）（增长了62%）；35至64岁年龄段的截短标准化率从18/10万（1961年）升至28/10万（1980年）：这两种类型的率之间存在高度相关性。2）处于乳腺癌风险中的女性人口（45岁以上）增加。绝经前年龄组中这种癌症的死亡率有选择性且显著上升，尤其是30至34岁年龄组（上升了160%）。女性乳腺癌死亡率的增加具有统计学意义。有必要研究这种增加的原因。
