Not All Estrogens Are Equal You may have heard that estrogen fuels breast cancer risk, but it’s more complicated than that.

Estrogen - whether made in the body or taken in externally from hormone therapy - is metabolized through pathways in the liver, forming estrogen metabolites. Estrogen metabolites interact with genetics, liver enzymes, antioxidants, and other biochemical pathways to ultimately influence breast cancer risk.

In May 2022, I was diagnosed with an early-stage breast cancer, detected by a routine screening mammogram. I chose to undergo a skin-sparing double mastectomy with reconstruction in late June 2022 and spent the summer recovering. Fortunately, the cancer was caught very early, and I was given an excellent prognosis without chemotherapy.
