Your Pap test is not checking for this.

My mother had a doctor. She had appointments. She was diagnosed with Stage IV endometrial cancer on Memorial Day of 1996 and she was dead by the middle of December, at fifty-three.

For a long time I assumed that meant someone had failed her. It is more uncomfortable than that. The system did roughly what it is built to do. It just is not built to find this.

What the Pap test actually does.

The Pap test is one of the most successful cancer screening tools ever deployed. It finds abnormal cells on the cervix, often years before they would become cancer, and it turned cervical cancer from a leading killer of women into something we mostly catch and remove.

It does that for the cervix. Only the cervix.

The CDC states it flatly on its own uterine cancer page: “The Pap test does not screen for uterine cancer.” On its ovarian cancer page: “The Pap test does not screen for ovarian cancer.” And more broadly: “Since there is no simple and reliable way to screen for any gynecologic cancers except for cervical cancer, it is especially important to recognize warning signs.”^1,2,3

Most women I have talked to about this, including women who work in healthcare, believed the number was five.

Why that misunderstanding is dangerous rather than merely incorrect.

A woman who believes she is being screened has a rational reason to wait. Something is a little off, and her next appointment is in four months, and the appointment is where the checking happens. So she waits.

A woman who knows she is not being screened has no reason to wait, because there is nothing scheduled that will find it. Her noticing is the mechanism. There is no other one.

Symptoms are not screening. When nothing is looking, noticing is the test.

Two thirds is better than most cancers manage, and it is not good enough.

About 67 percent of cases are caught at that local stage. That is better than most cancers manage and it is also not good enough, because the remaining third is where nearly all of the dying happens.⁴

Endometrial cancer is one of the very few cancers in the United States whose death rate is still going up rather than down, rising 1.6 percent a year from 2014 through 2023.⁵

The symptom that matters more than all the others.

Abnormal bleeding.

A National Cancer Institute analysis pooling 129 studies and more than 40,000 women found that 90 percent of women diagnosed with endometrial cancer had reported bleeding before their diagnosis.⁶ Nine out of ten. The signal was there, and it was there early, and it was there in almost everybody.

The same analysis found that about 9 percent of postmenopausal women who went to a doctor about bleeding turned out to have endometrial cancer. So most bleeding is not cancer. That is worth saying clearly, because fear is not the goal here. But roughly one in eleven is not a rounding error, and it is nowhere near low enough for anyone to be told to watch and wait.

What counts as abnormal depends on where you are. After menopause, any bleeding at all, including a single episode of spotting you could describe as barely anything. Before menopause, bleeding between periods, periods that have become much heavier or much longer than yours used to be, or bleeding after sex.

The CDC groups the rest by cancer type.³ Abnormal vaginal bleeding or discharge is common to every gynecologic cancer except vulvar. Feeling full too quickly, difficulty eating, bloating, and abdominal or back pain point toward ovarian. Pelvic pain or pressure occurs in both ovarian and uterine. More frequent or urgent urination and constipation occur in ovarian and vaginal. Itching, burning, pain, tenderness, or a change in the colour or skin of the vulva belong to vulvar cancer alone.

Read that list and you will notice the problem. Almost every item on it is also a description of an ordinary week.

This is not only a disease of older women.

The average age at diagnosis is 60, and the median is 63. Most cases are in older women and that is not in dispute.⁴

What has changed is the understanding of who else is at risk. A 2024 analysis in the Journal of the National Cancer Institute pooled 25 studies through the Epidemiology of Endometrial Cancer Consortium and looked specifically at 1,639 women diagnosed before the age of fifty. It found that the risk factors in younger women are not simply a milder version of the older pattern. They compound differently, and body mass index was the strongest single one.⁷

About 7.3 percent of uterine cancer diagnoses occur in women under 45.⁴ That is a small share of a large and growing number, and every one of those women was, statistically speaking, not who anyone was looking for.

If you are under fifty and you are bleeding in a way that is not normal for you, your age is not a reason to be reassured. It is the most common reason women in that group get sent home.

Four things that are actually within your control.

If something has changed, write down when it started. A date is harder to talk you out of than a feeling.

Ask for the specific thing. “I would like this evaluated for endometrial cancer” gets a different appointment than “I have been having some irregular bleeding.”

If you are told to wait and see and you do not feel heard, ask for the reasoning to be written in your chart. Nothing focuses a clinical conversation faster, and it is your record.

And if you are not the woman in this story but you love one, you are allowed to be the person who says out loud that this has been going on too long. Often you are the only one who will.
