Question

Ovarian cancer: Still possible after hysterectomy?

Is ovarian cancer still possible after a hysterectomy? If this is true, should I continue to have regular Pap tests?

Answer

from Timothy Moynihan, M.D.

Yes, you still have a risk of ovarian cancer or a type of cancer that acts just like it (primary peritoneal cancer) if you've had a hysterectomy.

Your risk depends on the type of hysterectomy you had:

  • Partial hysterectomy or total hysterectomy. A partial hysterectomy removes your uterus, and a total hysterectomy removes your uterus and your cervix. Both procedures leave your ovaries and fallopian tubes intact, so you can still develop ovarian cancer.
  • Total hysterectomy with salpingo-oophorectomy. This procedure removes your cervix and uterus as well as both ovaries and fallopian tubes. This makes ovarian cancer unlikely. But you still have a small risk of primary peritoneal cancer, which acts just like ovarian cancer and is treated similarly. It's not clear why the risk of peritoneal cancer remains.

A Pap test is a screening test for cervical cancer, but it can't detect ovarian cancer. Currently there are no effective screening tests for ovarian cancer. If you've had your cervix removed as part of a total hysterectomy, you usually don't need an annual Pap test. But if your hysterectomy was done because cancer or abnormal cells were detected, doctors recommend continued Pap tests.

You may still need regular pelvic exams after hysterectomy. Ask your doctor how often you should have a pelvic exam.
