Bleeding After Menopause: A Symptom to Report

This page is for anyone who has vaginal bleeding after menopause, and for the people who support them. It explains why any bleeding needs a doctor, what tests to expect, and how quickly to act.

After menopause, no amount of vaginal bleeding counts as normal. So there is nothing here to watch and wait on.

• Call 911 or go to an emergency department if the bleeding does not stop, soaks through protection, or you pass large clots. Do not drive yourself.
• Call 911 or go to an emergency department if bleeding comes with dizziness, fainting, breathlessness, a racing heart, or pale or blotchy skin. Do not drive yourself.
• Call 911 or go to an emergency department if you have a very high temperature with shivering, confusion, or fast breathing. Do not drive yourself.
• Call your care team the same day if you have any bleeding at all: one episode, light spotting, or pink or brown discharge.
• Call your care team the same day if bleeding comes with pelvic pain, a swollen abdomen, foul-smelling discharge, or unintended weight loss.

Any vaginal bleeding after menopause needs to be checked by a doctor. The National Cancer Institute lists "vaginal bleeding after menopause" among the signs you should "check with your doctor" about. As Dr. Megan Clarke, the NCI epidemiologist who led the analysis below, put it, "If you have bleeding after menopause, you should call your doctor and let them know."

That applies to a single bout of spotting. It applies to bleeding that stops on its own. It applies to blood you only see on toilet paper. No amount is too small to mention. There is no reason to wait and see if it happens again.

Bleeding is the main warning sign of endometrial cancer. This is cancer that starts in the lining of the uterus (womb). In an NCI analysis of 129 studies covering more than 40,000 women, 90% of women diagnosed with endometrial cancer had reported vaginal bleeding before their diagnosis.

Looked at from the other direction, 9% of postmenopausal women who saw a doctor about bleeding turned out to have endometrial cancer. That figure ranged from about 5% in North America to 13% in Western Europe. So most postmenopausal bleeding is not cancer. Gynecologic oncologist Dr. Christina Chu commented on the findings for NCI. She described it this way: "For the majority of women, it's a benign problem, but there are simple things that can be done to rule out endometrial cancer."

Timing matters because of what is at stake. NCI reports about 95% five-year survival when endometrial cancer is found early. That compares with 16% to 45% once it has spread beyond the uterus.

Bleeding can happen when starting hormone replacement therapy. NCI's Dr. Megan Clarke noted that "it's only if there's persistent bleeding after the initial 6 months" of hormone replacement therapy "that it may be more concerning." Tell your doctor either way. Say when you started the medicine and when the bleeding began. Taking estrogen-only HRT after menopause also raises the risk of endometrial cancer.

Bleeding is not the only sign to mention. NCI also lists these signs to check with your doctor about.

• Vaginal bleeding or discharge not related to menstruation.
• Difficult or painful urination.
• Pain during sexual intercourse.
• Pain in the pelvic area.

Risk factors NCI names include:

• Estrogen-only hormone replacement therapy.
• Taking tamoxifen.
• Obesity and metabolic syndrome.
• Type 2 diabetes.
• Never having given birth.
• Early menstruation or late menopause.
• Polycystic ovary syndrome.
• A family history of endometrial cancer.
• Lynch syndrome.
• Endometrial hyperplasia.

Having risk factors does not make cancer certain. Having none does not mean the bleeding can be ignored.

Expect a history and a pelvic exam first. From there, the tests NCI describes include the following.

Transvaginal ultrasound. An ultrasound wand is placed in the vagina. Sound waves make pictures of the uterus and nearby tissue.

Endometrial biopsy. Your doctor removes a small amount of tissue from the endometrium, the inner lining of the uterus. This is done with a thin, flexible tube passed through the cervix. In NCI's reporting, Dr. Chu described this as a simple procedure, similar to a Pap smear. She said it can be done in the doctor's office without anesthesia.

Hysteroscopy. A procedure to look inside the uterus for abnormal areas. A thin scope is passed through the vagina and cervix into the uterus.

Dilatation and curettage, or D&C. A procedure to remove samples of tissue from the inner lining of the uterus. The cervix is widened, and a spoon-shaped instrument removes tissue from inside the uterus.

Not everyone needs all of these tests. In NCI's modeling, at an assumed 10% risk level with ultrasound screening, roughly 7 women would need a biopsy for every 1 cancer found. In other words, most biopsies come back reassuring.

Call your doctor's office when you notice the bleeding. Do not wait for a routine visit. Say the words "bleeding after menopause" when you book. That phrase tells a scheduler this is not a routine visit.

Before you go, write down:

• The date bleeding started.
• How many episodes there have been.
• How heavy each was.
• The date of your last period.
• Every medicine and supplement you take, including hormone therapy and tamoxifen.

Ask what the plan is if the first test is normal but the bleeding continues. Ongoing bleeding still needs an answer.
