If you've been diagnosed with breast cancer or have tested positive for an abnormal breast cancer gene ( BRCA1 or BRCA2 ) and so are at high risk, you shouldn't use HRT. The hormones in HRT can cause hormone-receptor-positive breast cancers to develop and grow. While only a few small studies have looked at HRT use in women with a personal history of breast cancer, the fact that HRT use increases breast cancer risk among women in general makes almost all doctors advise women with a personal history of breast cancer to avoid HRT. The prescribing sheet included with HRT clearly states that it is "contraindicated in women with a diagnosis of breast cancer." Not being able to use HRT can present a challenge for many women. If you're having severe hot flashes or other menopausal side effects and have a personal history of breast cancer, talk to your doctor about non-hormonal options, such as dietary changes, exercise, weight management, acupuncture, or meditation.
This is a very informative article and has helped me understand more about hormone replacement therapy, I am a pre-op MTF transgender and hoping to get onto prescription hormones in the next 12 months. Also, thanks for the amazon purchase link above in the comment reply to patricia for the ‘ ProEstro estrogen pills ‘ – I started taken those pills along with the ‘ Life-Flo Biestro Body Cream ‘ after reading this article and I have noticed an increase in my breast size already for which I am happy and grateful to you.
