Estrogen alone did not show an increased risk of breast cancer, while estrogen plus progestin did, with conjugated estrogen even showing a reduction in breast cancer risk, but caution is advised in generalizing these findings to all estrogen formulations.
37:55
The Women's Health Initiative study was stopped due to an increased risk of breast cancer and an overall unfavorable risk-benefit ratio, leading to significant changes in clinical practice regarding hormone therapy use.
43:51
The Women's Health Initiative study results were possibly blown out of proportion, leading to a decrease in hormone therapy use for treating hot flashes and night sweats in early menopause, despite the low absolute risks involved.
50:15
Hormone therapy has complex effects with benefits and risks that vary depending on individual factors, and decision-making should be personalized and shared between women and their clinicians.

HRT has benefits such as reducing breast cancer cases and hip fractures, but the long-term use for bone health may not be beneficial due to rapid bone loss after stopping therapy, with younger women in early menopause showing more favorable outcomes.
01:02:52
HRT shows potential benefits in reducing hot flashes and night sweats, while the mortality results indicate a possible decrease in risk for younger women in their 50s compared to older women in their 70s.
01:09:11
The Women's Health Initiative results led to a shift towards transdermal estradiol and micronized progesterone in hormone therapy, indicating a need for more randomized trials with current formulations to assess long-term benefits and risks, particularly in relation to breast cancer risk.
