Quick Summary
- Usually benign, sometimes concerning
- Bleeding is the main symptom
- Pain is possible, less common
- Small cancer risk exists
- Removal is quick and effective
You leave your ultrasound appointment feeling fine, and then you hear the words, “We found a polyp.” Suddenly, your mind is racing. “Is it cancer?” “Do I need surgery?” “Should I be worried?” I completely understand why those questions come up. In my Chicago practice, many women arrive feeling anxious after hearing the word “polyp.” The name sounds alarming, even though the reality is often much less frightening. The good news is that most endometrial polyps are not cancerous . In fact, the majority are benign growths that can often be treated easily. At the same time, a small number can contain abnormal or cancerous cells, which is why they shouldn’t simply be ignored. The goal isn’t to panic. The goal is to find out exactly what you’re dealing with so we can make the right decision together. Let’s talk about what endometrial polyps are, the symptoms to watch for, when they’re considered concerning, and what treatment usually looks like.
What Are Endometrial Polyps?
Endometrial polyps are small growths that develop inside the uterus. They grow from the endometrium, which is the tissue that lines the inside of the uterus and sheds during your menstrual period. These growths can vary quite a bit. Some are only a few millimeters across, while others can grow several centimeters in size. A woman may have one polyp or several at the same time. Although doctors don’t always know exactly why they develop, estrogen—the hormone that helps build the uterine lining each month—appears to play a major role. I tend to see endometrial polyps most often in women who are approaching menopause or have already gone through menopause, although they can occur at younger ages as well.
Are Endometrial Polyps Dangerous?
This is usually the first question patients ask me. The honest answer is reassuring. Most endometrial polyps are harmless. They aren’t cancer, and they don’t become dangerous simply because they’re present. However, a small percentage—about 5% , or roughly 1 in 20 —may contain precancerous or cancerous cells. That risk becomes higher after menopause and in women with certain medical conditions.
Factors that may increase the chance of abnormal cells include:
- Being postmenopausal
- Obesity
- High blood pressure
- Taking tamoxifen for breast cancer treatment
- Certain forms of hormone therapy
Because it’s impossible to know whether a polyp is completely benign just by looking at it on an ultrasound, removal and laboratory testing are often recommended when symptoms are present or when a woman has additional risk factors. I always explain to my patients that sending the tissue to the lab doesn’t mean we expect bad news. It’s simply the safest way to make sure nothing important is missed.
What Is the Most Common Symptom of an Endometrial Polyp?
Interestingly, many women never know they have one.
Quite a few polyps are discovered by accident during an ultrasound performed for another reason.
When symptoms do occur, bleeding is by far the most common.
You may notice:
- Bleeding between periods
- Menstrual periods that are heavier than usual
- Longer-lasting periods
- Spotting after intercourse
- Bleeding after menopause
- Occasional watery or blood-tinged vaginal discharge
If you’ve gone through menopause and notice any vaginal bleeding , even if it’s only a small amount, please schedule an appointment promptly. Most cases aren’t caused by cancer, but every episode deserves evaluation.
Can an Endometrial Polyp Cause Pain?
Yes, But pain isn’t usually the first symptom. Most women with endometrial polyps experience abnormal bleeding rather than pelvic pain. When discomfort does happen, it’s often described as mild cramping or pressure in the lower abdomen.
Pain may occur if:
- The polyp becomes larger.
- It extends through the cervix.
- The uterus contracts around it.
Pelvic pain can also be caused by many other gynecologic conditions, including fibroids, ovarian cysts, endometriosis, or infection. That’s why I never like to assume pain is coming from one particular source until we’ve completed an examination and, if needed, imaging. The presence of pain doesn’t automatically mean something serious is happening. It simply means we should investigate further.
When Should You Schedule a Gynecology Appointment?
Some symptoms shouldn’t wait. I recommend scheduling an evaluation if you notice:
- Bleeding after menopause
- Bleeding between periods that continues for more than one or two cycles
- Heavy menstrual bleeding that interferes with daily life
- Ongoing pelvic pain
- Pain during intercourse
- Difficulty becoming pregnant
- An ultrasound showing a possible uterine polyp
Many women hesitate because life is busy. Between work, family responsibilities, and everything else, it’s easy to put your own health at the bottom of the list. Please don’t. The earlier we identify the cause of abnormal bleeding, the sooner we can decide whether treatment is needed.
What Are the Treatment Options for Endometrial Polyps?
Treatment depends on several factors. I look at:
- Your symptoms
- Your age
- Whether you’ve reached menopause
- Your plans for future pregnancy
- Your overall health
- Your individual cancer risk
For small polyps that aren’t causing symptoms in younger women, careful observation may be appropriate. Some disappear on their own. Hormonal medications may help reduce bleeding for certain patients, although they don’t always eliminate the polyp itself. When symptoms are significant—or when there’s concern about abnormal cells—the best treatment is usually removal.
What Happens During an Endometrial Polyp Medical Procedure?
Before recommending treatment, we first confirm that a polyp is actually present. This may involve:
- A transvaginal ultrasound
- A saline sonohysterogram, where sterile fluid improves the ultrasound view
- An endometrial biopsy in selected situations
If removal is recommended, the standard procedure is called a hysteroscopic polypectomy. During this minimally invasive procedure, I place a thin camera, called a hysteroscope, through the cervix and into the uterus. This allows me to see the polyp directly and remove it with specialized instruments. There are no abdominal incisions. Most procedures are performed on an outpatient basis, meaning you go home the same day.
Afterward, it’s common to have:
- Mild cramping
- Light spotting
- A day or two of reduced activity
Every polyp that is removed is sent to the laboratory for examination. Again, this is routine. It’s simply the best way to confirm that the tissue is benign. Although treatment is usually very successful, polyps can occasionally return, which is why regular gynecologic follow-up remains important.
Why Getting Answers Early Matters
One of the hardest parts of medicine is uncertainty. Not knowing why you’re bleeding—or wondering whether a polyp could become something more serious—creates stress that many women carry for weeks or even months. An evaluation provides answers. Sometimes those answers are wonderfully reassuring. Other times, they allow us to catch changes early, when treatment is often simpler and more effective. Either way, you deserve clarity. If you’ve been told you have an endometrial polyp or you’re experiencing abnormal bleeding, don’t spend weeks searching online and imagining every possible outcome. Let’s figure it out together. A thoughtful evaluation can help determine whether observation, removal, or another treatment is the right choice for you.
Frequently Asked Questions
Do all endometrial polyps need to be removed?
Not always. Small polyps without symptoms in premenopausal women can sometimes be monitored. Removal is more commonly recommended when symptoms develop, fertility is affected, or the patient has reached menopause.
Can endometrial polyps make it harder to get pregnant?
Yes. In some women, polyps may interfere with implantation, which is why removal is sometimes recommended during a fertility evaluation.
Is bleeding after menopause always caused by a polyp?
No. Bleeding after menopause has many possible causes. A polyp is one possibility, but every episode should be evaluated to rule out other conditions.
How long does recovery take after hysteroscopic polypectomy?
Most women return to normal activities within one or two days. Mild spotting and light cramping are common during recovery.
Can endometrial polyps come back?
Yes. Although removal is usually successful, new polyps can develop over time. Regular gynecologic checkups help identify any recurrence early.
