"If women have menstrual disorders, they can use contraceptives to regulate them." Professor Feng Limin, director of Obstetrics and Gynecology of Beijing Tiantan Hospital Affiliated to Capital Medical University, said in an interview with the all media reporter of China Women's Daily recently that some girls have menstrual disorder after menarche. When seeing a doctor, if the doctor recommends contraceptive treatment, many parents will refuse. Even if girls receive contraceptive treatment, many patients will stop after taking it for a period of time. "I mentioned at an international exchange conference that the rejuvenation of endometrial cancer in China is very obvious. A Chinese American doctor said that it is because Chinese young people do not take contraceptives." Feng Limin said that in the concept of many Chinese people, contraceptives contain hormones and should be "avoided" as much as possible. So, is the contraceptive effective in preventing endometrial cancer? Feng Limin said that the contraceptive pill is not only for contraception, but also has therapeutic effect. The current three generations of oral contraceptives are mainly progesterone, supplemented by estrogen, in which the content of estrogen is very low. Studies have shown that people who have taken three generations of oral contraceptives for more than ten years, people who have not taken them for more than ten years and people who have never taken three generations of contraceptives. Compared with these three groups, the longer they take contraceptives, the lower the risk of endometrial and ovarian cancer. It can be seen that the ratio of estrogen and progesterone of the three generations of oral contraceptives has a good protective effect on endometrium and ovary. It should be noted that taking contraceptives to regulate menstruation also has a premise: girls do not have tumors, and menstrual disorders are not caused by tumors. And it should be used selectively under the advice of doctors. You can't take it yourself. (outlook new era)
