It has been well known that soy food may have a protective effect against breast cancer including estrogen receptor negative breast cancer. A new study finds that long term soy foods prevent breast cancer such as very dangerous triple negative breast cancer by increasing the expression of genes for tumor suppressors and decreasing the expression of oncogenes.Remember that the best preventative against breast cancer is staying away from medical radiation and hormone replacement therapy, according to an authoritative organization.
