We all know that menopause is the absence of menstruation. Why is it that menstruation, which has been pestering us for so many years, doesn’t come when we say it does? Why should I stop having periods after menopause? The machine has been working for a long time there is wear and tear, ovaries work for a long time, naturally will also be “tired” it, secretion of estrogen fluid can not keep up, so the menstruation will not come. Some people have bleeding again after menopause, huh? Is it menstruation again? Don’t be happy, these bleeding disguised as menstruation, may be because the body has saboteurs oh. The saboteurs are masked and may be endometrial cancer, cervical cancer or senile vaginitis. To unmask these saboteurs and bring them to justice, they need to be diagnosed by a doctor. In the case of endometrial cancer, for example, because the uterus and vagina are connected, bleeding will be revealed as the first symptom whenever there is a tumor doing evil. The amount of bleeding is not very large, usually a little bit. When a doctor encounters postmenopausal bleeding, he or she will first examine the vagina to see if the bleeding is coming from the cervical area or the vagina. If no bleeding is found in the cervix or vagina, the doctor will usually need to do an ultrasound to see what is going on inside the uterine cavity. The thickness of the endometrium should not exceed 5mm after menopause. If the ultrasound reveals abnormal signals in the uterine cavity or if the thickness of the endometrium exceeds 5mm, it means something is wrong! The next step may be to do a hysteroscopy, where the doctors take a mirror in and reach inside the uterus under anesthesia to see if the uterus is still safe as a “hostage”. If the hysteroscopy reveals that the hostage has been compromised, a biopsy is usually needed to obtain pathology. Of course, in addition to endometrial cancer, endometrial polyps are also a common cause of endometrial thickening and bleeding after menopause, and hysteroscopy can be performed to “cut” the polyps while examining them. If endometrial cancer is diagnosed, there is still surgery as the “ultimate killer”. Because endometrial cancer is usually detected when the tumor has not yet become a climate, it can be extinguished through surgery, with a survival rate of more than 90% in 5 years. Therefore, when postmenopausal bleeding occurs, the most important thing is to seek timely medical consultation. Even a drop of blood is not acceptable. In case of delay, once the tumor spreads beyond the uterus, the treatment will not be as effective.
