...really looking forward to the year 2005. That's when a large clinical trial called the Women's Health Initiative (WHI) should finally answer the question "Do the benefits of taking estrogen and progestin for years, even decades, after menopause outweigh any risks?" There has been lots of evidence over the years that the answer is yes and yet plenty of data that lean toward no. Just last week a report in the Journal of the American Medical Association said that taking estrogen for 10 years or more doubles a woman's risk of dying from ovarian cancer...
...ESTROGEN It still soothes hot flashes and protects your bones, but two major studies showed that taking estrogen long after menopause may not benefit the heart. In fact, the potent female hormone may slightly increase the risk of suffering a heart attack in some women. A long-term study is expected to produce a definitive answer some time during the next five years or so. Until then, women with high cholesterol levels should get plenty of exercise, limit the amount of saturated fat in their diet and listen carefully if their physician suggests taking a cholesterol-lowering drug...

...than others when they sit for long periods of time--in the air or on the ground. The folks who have the most reason to be concerned are those with a history of stroke or heart conditions; people older than 65; cancer patients; and anyone with elevated estrogen levels, such as pregnant women or patients taking estrogen supplements. There are also several circulatory disorders that can make the blood more susceptible to clotting. None of these necessarily means you can't fly; but you should be more careful...
What merits another look, some researchers believe, is a suite of chemicals used to make plastics. One is Bisphenol A, or BPA. Like DDE and PCBs, it is a chemical cousin of estrogen's, and it has been shown to affect the reproductive systems of lab mice. Another category of plastics ingredients, phthalates, may have played a role in a rash of cases of very early puberty in Puerto Rico back in the 1980s, with girls as young as 2 growing breasts and pubic hair. And while no cause has yet been determined, a study published last month suggests that...
