Hysteroscopic endometrial curettage is not very harmful, and patients need to understand the extent to which the procedure can be harmful or beneficial, and need to be clear about the significance of performing a hysteroscopic curettage as well as the specifics of the procedure. If a woman has abnormal uterine bleeding or other indications, a hysteroscopic endometrial scraping is needed, often to further define or identify any obvious abnormal proliferation under the endometrium or corresponding tumor growths, in order to rule out or clarify the treatment plan, and the diagnostic significance of endometrial diagnosis under hysteroscopic scraping is relatively high, and the corresponding possibility of secondary infection or chronic inflammation of the uterine cavity is relatively low. The likelihood of secondary infection or chronic inflammation of the uterine cavity is low. Therefore, the advantages of hysteroscopic scraping clearly outweigh the disadvantages, and it is necessary to perform the procedure in order to improve the subsequent diagnostic purpose and specificity of the treatment.
