美國科學(xué)家的一項(xiàng)最新研究顯示,，女性常喝咖啡和飲茶能降低罹患子宮內(nèi)膜癌的風(fēng)險(xiǎn),。
美國羅斯韋爾·帕克癌癥研究所科學(xué)家在4月刊的美國《國際癌癥雜志》（International Journal of Cancer）上發(fā)表報(bào)告說，他們對(duì)近1100名婦女進(jìn)行跟蹤調(diào)查后發(fā)現(xiàn),，常喝咖啡和飲茶的人罹患子宮內(nèi)膜癌的風(fēng)險(xiǎn)要比未飲用者低,，而且喝咖啡和飲茶的次數(shù)越多，患這種癌癥的風(fēng)險(xiǎn)就越小,。
報(bào)告說,，每天喝咖啡或飲茶4杯以上者，患子宮內(nèi)膜癌的風(fēng)險(xiǎn)要比未飲用者低約50％,。平均每天飲茶或者喝咖啡2杯者,，患這種癌癥的風(fēng)險(xiǎn)要比未飲用者分別低44％和29％。
報(bào)告說,，至于茶和咖啡為何能起到降低患子宮內(nèi)膜癌風(fēng)險(xiǎn)的作用,，仍需進(jìn)一步進(jìn)行研究。不過參與研究的科學(xué)家麥卡恩說,，他們的研究發(fā)現(xiàn),，飲用不含咖啡因的咖啡與降低患子宮內(nèi)膜癌風(fēng)險(xiǎn)之間沒有任何關(guān)系，因此就咖啡來說,，可能是咖啡因在預(yù)防子宮內(nèi)膜癌方面發(fā)揮了某種作用,。
子宮內(nèi)膜癌為女性常見的惡性腫瘤之一，其發(fā)病率僅次于乳腺癌和宮頸癌,。（生物谷Bioon.com）

ABSTRACT
Several studies have investigated the associations between diet and endometrial cancer, but few have focused specifically on coffee and tea. In a hospital-based case-control study, we examined the associations between endometrial cancer risk and usual consumption of coffee, decaffeinated coffee, and black tea among 541 women with endometrial cancer and 541 women with an intact uterus but without a cancer diagnosis seen at Roswell Park Cancer Institute (Buffalo, New York) between 1982 and 1998. Daily frequency of consumption of coffee, decaffeinated coffee, and black tea in the few years prior to diagnosis in cases and questionnaire completion in controls was assessed with a self-administered epidemiologic questionnaire and categorized as none, 0.5 cups/d, 1-2 cups/d and >2 cups/d. Odds ratios (OR) and 95% confidence intervals (CI) for each category referent to nondrinkers were estimated with unconditional logistic regression adjusting for age, endometrial cancer risk factors and each beverage mutually adjusted for other beverages. Compared to nondrinkers, we observed a nonsignificant negative association with endometrial cancer risk among women who reported >2 cups/d regular coffee (OR 0.71, 95% CI 0.49-1.03), a significant inverse association with >2 cups/d black tea (OR 0.56, 95% CI 0.35-0.90) and a significant inverse association with >4 cups/d combined coffee and tea consumption (OR 0.47, 95% CI 0.28-0.80). These findings suggest coffee and tea may be important in reducing endometrial cancer risk. ? 2008 Wiley-Liss, Inc.
