Environmental magnetic fields inhibit the antiproliferative action of tamoxifen and melatonin in a human breast cancer cell line

By Harland JD, Liburdy RP Life Science Division, Lawrence Berkeley National Laboratory, University of California at Berkeley 94720, USA. “We have previously reported that environmental-level magnetic fields (1.2 microT [12 milligauss], 60 Hz) block the growth inhibition of the hormone melatonin (10(-9) M) on MCF-7 human breast cancer cells in vitro. We now report that the same 1.2 microT, 60 Hz magnetic fields significantly block the growth inhibitory action of pharmacological levels of tamoxifen (10(-7) M).” View at PubMed: http://www.ncbi.nlm.nih.gov/pubmed/9383244
