I was over the moon when, in 2002, the first ever independent, randomised, double blind study ever done on oestrogen  was stopped after only 5 years because the risk of breast cancer had doubled.  This was the famous WHI (Woman’s Health Initiative), a government study that showed that HRT (Hormonal Replacement Therapy drugs), taken by millions of women, could expose them to higher risks cancer. A year later, in 2003, another huge study in the U.K. was also halted.  Taken together, these two studies showed that the combination of the drugs oestrogen with progestins (a so-called drug equivalent to progesterone) exposed women to far higher risks of heart attacks, strokes and breast cancer. Many medical scientist began recommending against the combination HRT as the risks outweigh the benefits. Another recent finding provides evidence that the combined HRT significantly boosts the risk of dementia and strokes in post menopausal women.
