I am not convinced modest consumption of soy is an offender for ER+ bc, however, there have been studies regarding elevated levels of iron (Fe), folic acid, and thiamine that seem to promote t cancer proliferation. I avoid iron, thiamine, and folic acid for that reason. They are nearly always present in high amounts in MVIs.
