Endometrial (uterine) cells may turn up on a Pap smear, making the patient think of possible uterine cancer.

Especially if her doctor wants a biopsy done despite a normal-looking ultrasound, this will leave the patient quite unnerved.

Two Questions

• If there’s no uterine cancer, why would endometrial cells show up on a Pap smear?

• If an ultrasound shows a normal uterus, why would the doctor want a biopsy performed?

“Benign endometrial cells are shed in great numbers during a menstrual period,” says Julian Schink, MD, Chief of Gynecologic Oncology, Cancer Treatment Centers of America; Medical Director of Gynecologic and Medical Oncology, Midwestern Regional Medical Center.

“The presence of these on a Pap smear is not evidence of cancer,” says Dr. Schink.

“Sometimes they are also picked up by the cytobrush placed into the cervical canal and coincidentally reaching the endometrial cavity.

“If US is normal, a biopsy would be indicated if there is an abnormal bleeding pattern, but not simply because of endometrial cells on a Pap.”
