'Natural' hormone replacement and breast cancer risk: evidence for safety and efficacy.

摘要

Many women have turned to natural forms of hormone replacement for menopause since learning that conventional hormone replacement therapy (HRT) may increase their risks of breast cancer and other health problems. Most women have assumed that "natural" or "bioidentical" HRT is safer than conventional HRT. However, recent research has shown that this is not the case and that, in fact, the risks are probably similar.
