In women with abnormal vaginal bleeding the biopsy may indicate the presence of abnormal lining such as endometrial hyperplasia or cancer. In patients with suspected uterine cancer, the biopsy may discover the presence of cancer cells in the endometrium or cervix. In female infertility the assessment of the lining can determine, if properly timed, that the patient ovulated, however, the same information can be obtained by a blood test of the progesterone level.
