What to Expect  

Prior to Procedure  

You may need to schedule the biopsy for a certain time during your menstrual cycle.

Your doctor may do the following:

  • Physical and pelvic exam
  • Blood tests
  • Urine test

Leading up to your procedure, you may be advised to:

  • Take a pain reliever one hour before the procedure
  • Wear or bring a sanitary pad

Anesthesia  

Usually none is needed. Sometimes local anesthesia is used to numb the cervix.

Description of the Procedure  

A speculum will be used to look into the vagina. An instrument called a tenaculum will be used to grasp the cervix. A flexible, thin, suction tube will be passed through the vagina and into the uterus. A small sample of endometrial tissue will be suctioned out.

Immediately After Procedure  

After the biopsy, you may feel lightheaded. Lying down for 5-10 minutes will help. When you feel better, you will be able to go home.

How Long Will It Take?  

About 10-15 minutes

Will It Hurt?  

You may feel some cramping and pressure during the biopsy. Your doctor may give you pain medication after the procedure.

Post-procedure Care

  • Expect some cramping and bleeding. Use sanitary napkins. Do not use tampons.
  • Ask your doctor when you can resume:
    • Using tampons
    • Having sex

Your doctor will receive results in about a week. She will work with you to create a treatment plan.
