We will begin the final year of data collection on a nested case-control study of the association between magnetic field and breast cancer risk among a group of predominantly African-American and Latino women in Los Angeles County. The research questions remain as follows 1 Is residential exposure to magnetic fields, as assessed by wiring configuration coding in homes occupied over the past 10 years before diagnosis, associated with the risk of breast cancer. Wiring configuration coding is a method that uses data on the types and distances to nearby outdoor electrical wiring to impute magnetic field levels in homes. 2 Do higher exposures to alternating current AC magnetic fields, as assessed by 7 days of measurements, increase a womans risk of breast cancer. Do particular combinations of the alternating current AC magnetic field and the direct current DC magnetic field increase the risk of breast cancer. The AC field results from our use of the 60 Hz electric power supplied by utilities the DC or static field results from the earths magnetic field but is altered by the environment within residences. This hypothesis was prompted by observations of biologic effects at particular combinations of the AC and DC fields in several experimental systems.
