雌激素异常易诱发子宫内膜癌 Abnormal predisposes to estrogen endometrial carcinoma

　　清华大学第一附属医院妇产科医生郭丽杰表示，其实人体内雌激素异常容易诱发子宫内膜癌，宫颈癌一般是由于病毒感染造成，属于性传播疾病。正常情况下，女性需要通过雌激素促进子宫内膜的增长，而长期排卵型的子宫内膜增生则容易导致子宫内膜癌。如果服用外源性的雌激素，体内激素水平较高也会导致子宫内膜过度增长。

清华大学The first附属医院妇产科医生郭丽杰表示,Actually the body estrogen induce abnormal endometrial cancer,cervical cancer is usually caused by a viral infection,Belong to sexually transmitted diseases.Under normal circumstances,Women need to promote the growth of endometrial estrogen,While long-term ovulation type endometrial hyperplasia can easily lead to endometrial cancer.If taking exogenous estrogen,Hormone level is high also can lead to excessive growth of the film inside the uterus.

　　郭丽杰建议，预防子宫内膜癌的出现，要避免外源性性激素的应用，如果要使用外源性性激素，要在有适应症的情况下遵照医生指导应用。鼓励女性哺乳，这也可以减少子宫内膜癌的发生。

郭丽杰建议,To prevent endometrial cancer,To avoid the application of exogenous hormones,If you want to use exogenous hormones,To have indications follow doctor guidance application.Encourage women to breastfeed,It can also reduce the occurrence of endometrial carcinoma.

　“补品”选择依个人体质而定 "supplements"The choice depends on the individual physique

　　国家二级公共营养师杨文娇告诉记者，从营养的角度来看，应注重保持营养均衡，人体本身是一个有机整体，过多食用某一类食物，有可能造成人体代谢紊乱，导致某些疾病的发生，如细菌感染等感染症状及癌症、慢性病。如腌制食品中亚硝酸盐的含量较高，有可能会生成致癌物亚硝胺。

国家二级公共营养师杨文娇告诉reporter,From the point of view of nutrition,Should pay attention to keep balanced,The human body itself is an organic whole,Too much eating one kind of food,Likely to cause human body metabolic disorders,Lead to some diseases,Symptoms such as infection such as bacterial infections and cancer/chronic diseases.Such as pickled food nitrite content is higher,Is likely to generate carcinogenic nitrosamines.

　　杨文娇表示，不可盲目进食保健食品、营养补充剂等。如，维生素A、C、E被称为“抗氧化铁三角”，锌、铁及硒也被证明对于抗衰老、抗氧化及增强免疫力有一定效果，但也有研究证明，这些抗氧化物质本身存在被氧化形成过氧化物的可能，如果过量摄入反而会对人体造成损害。一些膳食补充剂，如果人们服用时没有把握好用量，有可能会产生过犹不及的效果。并不建议健康人群摄取营养补充剂。杨文娇建议，可以选择一些营养强化食品，一般这类食品会在包装中予以标示，如含铁酱油、营养强化面粉等，既能保证营养的摄入，安全性也较高。

杨文娇表示,Not blindly eat health food/Nutritional supplements, etc..Such as the,Vitamin A/c/E is known as"Oxidation iron triangle",zinc/Iron and selenium are also proved for anti-aging/Antioxidation and enhance immunity has certain effect,But research has shown, too,These antioxidants may itself exists was oxidized to form oxides,If the excessive intake may cause damage to human body.Some dietary supplements,Such as the果人们服用when没有把握好用量,Is likely to result in too much of a good thing.Do not recommend healthy people taking nutritional supplements.Ellen pau jiao advice,can choose a few fortified foods,In general this kind of food will be marked in the packing,Such as iron soy sauce/Fortified flour, etc,can not only guarantee the nutrition intake,Security is also high.
