Endometrial biopsy is a safe and effective method for evaluation of the tissue lining the inside of the uterus (or womb) for the presence of cancer or precancerous cells. Most women who have this procedure done have abnormal uterine bleeding, or prolonged absence of their period (amenorrhea). A plastic catheter is slipped into the uterus, and small amount of the endometrial lining is suctioned into the catheter. The sample is sent to the hospital for examination by a specialist physician called pathologist. Your doctor will want to talk to you about the treatment plan that is best for you once the report of the tissue examination is completed. A number of our physicians perform this procedure in our clinics.
