An endometrial biopsy involves collecting a small sample of tissue from the endometrium, which is the lining of the uterus. Once the sample is obtained, it is examined for signs of abnormal cells and for the impact of hormones on the tissue.

Your doctor may recommend an endometrial biopsy for several reasons:

  • To detect abnormal, pre-cancerous cells, or cancerous cells
  • To look for signs of infection
  • To assess the impact of hormone replacement therapy
  • To pinpoint the cause of heavy uterine bleeding
  • To assess whether the uterus can carry a pregnancy
