Normal pathologic results of diagnostic curettage will report proliferative endometrium and secretory endometrium, which are benign lesions, and pathologic reports of atypical hyperplasia, which are precancerous lesions. If endometrial adenocarcinoma is reported to be cancerous, women with ovulation disorders such as polycystic ovary syndrome, dysfunctional uterine bleeding, some of them will show irregular vaginal bleeding, bleeding for a long time, heavy, recurrent and lead to anemia. If not improved by bleeding medication, in order to clarify the diagnosis and treatment, diagnostic scraping should be done to send the pathology examination, if suggestive of proliferative and secretory endometrial changes, indicating that the hormone level in the female body is disturbed, and medication can be used to adjust the ovarian function. If the pathologic result of diagnostic scraping shows precancerous changes, it is necessary to give a large amount of progesterone or surgery as early as possible for thorough treatment, and if it is cancerous, it is necessary to operate in order to improve the cure rate.
