However, the risk was similar for outdoor and indoor LAN exposure. A marginally stronger risks were observed for premenopausal women and for women with estrogen receptor positive breast cancer.<\/p>\n\n\n\n<p>Hence, the excessive exposure to artificial LAN increases the breast cancer risk, especially in premenopausal women and for women with estrogen receptor positive breast cancer.<\/p>\n\n\n\n<p>Source: Urbano T, Vinceti M, Wise LA, Filippini T.
