You're hormone statements are not quite correct. Much of the information which you are giving is based on synthetic hormones, progestins and oral hormones. The research and dangers for that form of HRT is found in the old WHI report. I agree that synthetic hormones and oral hormones can be dangerous and are tied to cancers and cardio events
BHRT, bioidentical hormones, those identical chemically to your own natural hormones are different.
BHRT, bioidentical hormones do not have the same risks as the old HRT.
Speaking directly about breast cancer, the largest study of different HRTs and breast cancer was done in France with over 80,000 women. The only group that showed ZERO increased risk for breast cancer was the group that used estrogen but with added BHRT progesterone.

How does progesterone act in our breasts related to breast cancer risk?

1. Estrogen causes cells to grow or proliferate—if that occurs without being limited or slowed, estrogen can promote genetic errors and possibly cancer.
2. Progesterone decreases proliferation/cell growth while encouraging cells to become more specialized or mature—progesterone’s actions decrease cancer risk.
3. When progesterone is present, its receptors make the estrogen receptor no longer able to cause breast cells to grow or proliferate."
In addition, bioidentical , BHRT estriol is frequently used instead of estradiol in BHRT therapy. Estriol is believed to be even more safe than estradiol, especially for breast health.
Indeed, many women use progesterone directly on their breasts to treat cystic breasts.
