le to isolate the benefits of red wine to the point that antioxidants, rather than 鈥渕oral affections鈥?can begin to take some of the credit.
But what about that other serial killer鈥攃ancer? Some studies have indicated that drinking alcohol of any kind, including wine, increases the risk of certain cancers. How does one reconcile this? One factor is that early studies lumped all alcohol together, failing to consider the effects of spirits, red wines and white wines separately. A hint to another factor may have been uncovered by a February 2007 study among women in a broad range of age groups. Research Triangle Park scientists found that peri- and post-menopausal women who used estrogen HT (hormone therapy) and drank wine increased their risk for ovarian cancer. Women who did not use HT, or used a combined estrogen-progestin HT had no increase in risk when they drank wine.
In recent years, the connection between hormone replacement therapy and estrogen-related cancers has been strengthening. In fact, the concern has been spreading to the point that the popularity of this therapy has dropped sharply . . . only to be followed by a corresponding drop in breast cancer rates. While some scientists hesitate to associate these factors directly, there is good reason to wonder whether conclusions can be drawn about alcohol consumption without controlling for hormone therapy use.
Another interesting thread in the tapestry can be pulled from a 2004 study conducted by researchers including Elizabeth Eng of the Beckman Research Institute at City of Hope in California. She and her colleagues were interested in previous research showing that estrogens in breast cancer tissue promote tumor progression. They also noted that 鈥渁pproximately 75 percent of postmenopausal patients have estrogen-dependent cancers,鈥?and that substances that inhibit aromatase are 鈥渁 viable means for preventing and treating breast cancer in postmenopausal上一页 [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] 下一页 更多英语知识学习请访问:英语学习
