[Epidemiology of breast cancer in Austria (author's transl)].
In cooperation with the Austrian National Institute for Statistics the incidence-rates of breast cancer in Austria in the period of 1971-1975 were investigated. The incidence-rate of breast cancer (50 new cases/year/100,000 women) is higher than the incidence-rate of cervical or endometrium carcinoma. The increasing risk of the higher age-groups, which is especially expressed by the incidence-rate of 145 in the age-group of 70 or more years, is pointed out. This findings are of great consequence to the system of preventive medical care. In urban areas the incidence of breast cancer seems to be higher than in rural district.
