Endometrial Biopsy | Brigham Wellesley OB/GYN Associates
Comprehensive women's health, every stage of life
Unexplained bleeding, whether it’s heavier than usual, happening between periods, or showing up after menopause, can be confusing, inconvenient, and deeply unsettling. It’s natural to want answers, and it’s just as natural to feel anxious about what those answers might be. At Brigham Wellesley OB/GYN Associates, we believe getting clarity about your body shouldn’t come with unnecessary fear or a rushed, impersonal appointment.
An endometrial biopsy is one of the most effective, reliable tools we have to understand what’s happening inside your uterus. It’s a simple, in-office procedure, that we take the time to walk you through exactly what to expect, answer every question you have, and make sure you feel supported before, during, and after your biopsy.
Whether your provider has recommended an endometrial biopsy to investigate abnormal bleeding, evaluate the lining of your uterus, or rule out more serious conditions, you deserve a clear explanation and a compassionate team by your side. To schedule your endometrial biopsy, call our Wellesley office at (781) 235-4000. You can also request an appointment online.

What Is an Endometrial Biopsy?
An endometrial biopsy is a procedure in which a small sample of tissue is taken from the endometrium, the lining of the uterus, and sent to a laboratory for evaluation. Examining this tissue under a microscope allows your provider to identify what’s causing abnormal bleeding or other symptoms and determine the right next steps for your care.
This procedure is one of the most common ways gynecologists investigate changes to the uterine lining, and it’s often preferred because it can typically be performed right in our office, without the need for general anesthesia or a hospital visit. While no one looks forward to a uterine procedure, an endometrial biopsy is brief, and we do our absolute best to ensure you feel comfortable and cared for every step of the process.
What Should I Expect During My Endometrial Biopsy?
We know procedures involving the uterus can cause anxiety, even when they’re minor. Our providers are committed to making sure you understand each step before it happens and that you never feel rushed through the process.
Before your biopsy, your provider will review your medical history, discuss your symptoms, and answer any questions you have. You may be advised to take an over-the-counter pain reliever about an hour before your appointment to help minimize discomfort.
During the procedure itself, you can expect:
Positioning
You will lie on the exam table in the same position used for a routine pelvic exam, with your feet in footrests.
Speculum Placement
Your provider will gently insert a speculum, just as they would during a Pap test, to get a good visual of the cervix.
Cervical Cleansing
The cervix is cleaned with an antiseptic solution to reduce the risk of infection.
Tissue Sampling
A thin, flexible instrument is passed through the cervix into the uterus to collect a small sample of endometrial tissue. This step typically causes brief cramping, often described as similar to strong menstrual cramps, which resolves quickly once the sample is collected.
Completion
The instruments are removed, and the tissue sample is sent to a laboratory for analysis. The entire procedure usually takes just a few minutes.
Most patients experience mild to moderate cramping during the biopsy and some light spotting afterward, but significant pain is uncommon, and shouldn’t last long. Your provider will discuss options to help manage any discomfort, and you are always encouraged to voice how you’re feeling throughout the appointment. We will help make you as comfortable as possible.
Why Might I Need an Endometrial Biopsy?
Your provider may recommend an endometrial biopsy for a number of reasons. Common reasons for this procedure include:
- Abnormal uterine bleeding, including bleeding between periods or unusually heavy periods
- Bleeding after menopause, which always warrants evaluation
- Irregular menstrual cycles that don’t resolve with initial treatment like birth control pills
- Monitoring the uterine lining for patients on certain hormone therapies
- Evaluating for endometrial hyperplasia, a thickening of the uterine lining
- Ruling out precancerous or cancerous changes to the endometrium
- Investigating suspected polyps or other structural changes noted on imaging
An endometrial biopsy is not a sign that something is necessarily wrong. It’s a diagnostic step, one that helps your OB/GYN understand your body clearly so you can move forward with confidence, whether that means reassurance, a treatment plan, or further evaluation.
How Should I Prepare for an Endometrial Biopsy?
Preparing for your endometrial biopsy is straightforward, and our team will give you specific guidance ahead of your appointment. In general, patients are advised to:
- Take an over-the-counter pain reliever, such as ibuprofen, about 30 to 60 minutes before the procedure, unless otherwise directed
- Avoid scheduling the biopsy if you suspect you may be pregnant, since the procedure is not performed during pregnancy
- Let your provider know about any bleeding disorders, allergies, or medications, including blood thinners
- Plan for the procedure to take place outside of your heaviest bleeding days, if possible, unless your provider advises otherwise
- Bring a panty liner or pad, since light spotting is common afterward
You do not need anesthesia or sedation for this procedure, and most patients are able to drive themselves home and resume normal activities the same day. If you have anxiety around being by yourself or driving yourself home, don’t hesitate to bring a companion along.
What Happens After My Endometrial Biopsy?
Mild cramping and light spotting or bleeding are normal for a day or two following your biopsy. Over-the-counter pain relievers and a heating pad can help manage any lingering discomfort. Most patients return to their normal daily routine, including work, the same day.
You may be advised to avoid tampons or intercourse for a short period after your biopsy to reduce the risk of infection while your cervix and uterine lining heal. Your provider will give you specific aftercare instructions before you leave your appointment.
Results from your biopsy are typically available within one to two weeks. Your provider will contact you to discuss your results and explain what they mean for your care, whether that’s reassurance, a treatment plan, or a referral for further evaluation. We never want you to wait in the dark, so if you haven’t heard from us within the expected timeframe, please don’t hesitate to call.
When Should I Contact My Provider After an Endometrial Biopsy?
While most patients recover from an endometrial biopsy without complications, you should contact our office if you experience:
- Bleeding that is significantly heavier than a normal period
- Fever or chills
- Severe or worsening pelvic pain
- Foul-smelling vaginal discharge
- Symptoms that concern you or don’t feel like they’re improving

Endometrial Biopsy FAQs
Is an endometrial biopsy painful?
Most patients experience brief, moderate cramping during the tissue sampling portion of the procedure, similar to strong menstrual cramps. This discomfort typically resolves within a few minutes, as the procedure itself is very quick. We do advise our patients to take an over-the-counter pain reliever beforehand if they feel comfortable doing so as this can help.
How long does an endometrial biopsy take?
The procedure itself usually takes just a few minutes, though your full appointment, including preparation and a brief recovery period, may take 15 to 30 minutes.
Do I need someone to drive me home after an endometrial biopsy?
Not necessarily. Since this procedure doesn’t require anesthesia or sedation, most patients are able to drive themselves home and resume their normal daily activities right away. However, if you took an anxiety medication or something that may have made you drowsy, we do recommend having a trusted friend or family member accompany you to and from your appointment.
How soon will I get my endometrial biopsy results?
Your results should typically be available within one to two weeks. Your provider will reach out to discuss your results and explain what they mean for your care.
Does an abnormal endometrial biopsy result mean I have cancer?
Not necessarily. Many abnormal results are related to benign conditions, such as hormonal imbalances or polyps. If your results do suggest something more serious, we will guide you through clear next steps and any further evaluation that may be needed.
