Curettage is a routine and safe procedure, it’s needed when an abnormal bleeding occurs between periods and the cause is unknown. The bleeding can be caused by hormonal imbalances, benign or even malignant tumors. These are important issues to discover and treat in time.
The surgery can be diagnostic or therapeutic: When it is done for a diagnosis, the doctor takes a tissue sample from the endometrium (the mucous membrane of the uterus) to examine the exact cause of the problems. When the cause is already known, or a surgery is necessary (for ex: to stop the bleeding) the doctor removes the endometrium. Even in the latter case the tissue is sent to histological examination.
