ConclusionConforms to USP36

Studies suggest that when the lower-potency estrogen, estriol, is administered topically, it does not increase the risk of hormone-dependent cancers of the breast or endometrium (uterine lining).1-3 However, having weaker estrogenic effects does not mean that estriol has none of the benefits that come with more potent estrogens. Studies suggest that estriol reduces symptoms of menopause, such as hot flashes and vaginal dryness, but with a better safety profile compared with more potent estrogens.1,4,5 This makes estriol a better choice for bioidentical hormone-replacement treatment regimes.
Estriol effects

Estriol can be a weak or strong estrogen depending on if it is given acutely or chronically when given to immature animals, but is an antagonist when given in combination with estradiol. 

Estriol may play a role in the development of breast cancer, but based on in vitro research, does appea to act as an antagonist to the G-protein coupled estrogen receptor. Though estriol is used as part of the primarily North American phenomenon of bioidentical hormone replacement therapy, it is not approved for use by the FDA or Health Canada.
