Description:
<p>Socioeconomic status has been regarded as an established risk factor for breast cancer. We have studied the association between socioeconomic status, operationalized as years of completed schooling, and breast cancer mortality in a Norwegian cohort. A total of 425,884 currently married women, aged 35-54 years at the Norwegian Census in 1970, was followed through 1985. No relation was found between level of education and breast cancer mortality.</p>
