AUTHORS' ABSTRACT: West et al. 2013 (IEEE #5317): Breast cancer occurring in women under the age of 40 is uncommon in the absence of family history or genetic predisposition, and prompts the exploration of other possible exposures or environmental risks. We report a case series of four young womenages from 21 to 39with multifocal invasive breast cancer that raises the concern of a possible association with nonionizing radiation of electromagnetic field exposures from cellular phones. All patients regularly carried their smartphones directly against their breasts
in their brassieres for up to 10 hours a day, for several years, and developed tumors in areas of their breasts immediately underlying
the phones. All patients had no family history of breast cancer, tested negative for BRCA1 and BRCA2, and had no other known
breast cancer risks. Their breast imaging is reviewed, showing clustering of multiple tumor foci in the breast directly under the area
of phone contact. Pathology of all four cases shows striking similarity; all tumors are hormone-positive, low-intermediate grade,
having an extensive intraductal component, and all tumors have near identical morphology. These cases raise awareness to the lack
of safety data of prolonged direct contact with cellular phones.
