The normal thickness of the endometrium is usually not more than 14mm, if the thickness of the endometrium is 17mm, at this time, if the menstruation is regular every time, the problem is not very big. If there are so many people who show that their menstruation does not go away and they keep dragging and dragging the bleeding, they should go for diagnostic scraping of the endometrium to see whether the pathology result is simple endometrial hyperplasia, complex endometrial hyperplasia, or whether there is an organic pathology of the endometrium, that is to say, there is endometrial carcinoma. If it is the first two cases, there is no need to worry, if there is endometrial cancer, you can have early surgery, the earlier the surgery, the better the recovery.
