One of our medical sources revealed to us a curious and previously unreported association between breast cancer and cellphone carriage in women's bras. Several manufacturers now make bras especially designed to carry cellphones next to a woman's breast. We investigated the breast cancer/cellphone link, interviewing patients, surgeons and radiologists to discover compelling cases of tumors "exactly" under the carried cellphone on women and men. We were first to report this medically significant association and a common-sense warning some doctors are now advising all patients.
