Using extensive census data on more than 1 million women and nearly two decades of follow-up, researchers have developed a list of occupations linked with a high risk of breast cancer in Sweden.
The study authors, from the Carlos III Institute of Health in Madrid and the Karolinska Institute in Stockholm, analyzed data from women employed in 143 occupations in 1970, and they followed the cohort until 1989. They found significant excess risk for breast cancer among pharmacists, certain types of teachers, schoolmasters, systems analysts and programmers, telephone operators, telegraph and radio operators, metal platers and coaters, and beauticians.
