[Breast neoplasm: health care and life quality in premature mortality]

Eight epidemiological indicators and eleven variables pertaining to the chilean population are analyzed regarding their possible relation to cancer of the breast. The observed and expected mortality rates are discussed. Multiple regression models are employed to evaluate their effect on health. The rate is 2.9 per 100,000 women in the age 30-34 years age group and 46.7 por 100,000 women in the 60-64 years age group. A one year increase in age elevates risk of cancer by 1.4 average.
