This brings me to the second phobia. You know: breast cancer. Data spanning the 50 years since the inception of BCH has repeatedly shown no association with breast cancer. Much of that research was done when pill doses were markedly higher than today.
The big Women's HealthInitiative, a poorly designed government study that put all MHT on its ear in 2002 found that the estrogen–only treatment group had no increase in breast cancer.
Suffice it to say, while we need more well-done research, females and their providers making decisions today have many reasons to confidently use hormones throughout life.
