Nabothian Cysts: Causes, Symptoms, and Why You Likely Don’t Need to Worry
If you have recently had a routine pelvic examination and your doctor mentioned “Nabothian cysts,” your first instinct might be to worry. The word “cyst” often triggers anxiety, but in the world of gynaecology, these are some of the most common and harmless findings imaginable. These benign growths are simply tiny bumps on the surface of your cervix, and they are usually discovered by accident during a routine check-up.
In this guide, we will break down exactly what these cysts are, why they form, and why they almost never require treatment. Think of this as your friendly, expert-led tour of a very normal part of female reproductive health.
What Exactly Are Nabothian Cysts?
A Nabothian cyst—sometimes referred to as cervical follicles or mucinous cysts—is a small, mucus-filled lump on the surface of the cervix. Your cervix is the bridge between your vagina and your uterus, and it is lined with various glands that produce mucus.
The Nabothian gland (or cervical gland) can sometimes become blocked by a layer of skin cells. When this happens, the mucus continues to produce but has nowhere to go, forming a small, firm pocket or “cyst.” These are typically white or pale yellow in colour and can range in size from a few millimetres to several centimetres.
How Do They Form?
The primary driver behind these cysts is a process called squamous metaplasia. This sounds complex, but it is actually a normal part of how the body adapts. During this process, the soft, glandular cells of the endocervical canal are replaced by tougher, protective skin cells. If these new cells grow over the openings of the mucus-producing glands, the mucus gets trapped.
According to research on squamous metaplasia, this cellular transition is quite common during puberty and menopause. Other factors that can trigger the formation of Nabothian cysts include:
- Childbirth: The physical changes and tissue repair following labour can lead to cell growth over the glands.
- Physical Trauma: Any minor injury to the cervix can stimulate the growth of new tissue.
- Chronic Cervicitis: Long-term inflammation of the cervix, often discussed in NHS medical guides, can contribute to gland blockage.
Recognising the Symptoms
For the vast majority of people, Nabothian cysts cause zero symptoms. You won’t feel them, and they won’t interfere with your daily life or menstrual cycle. However, in rare cases where a cyst becomes unusually large, you might experience:
- A feeling of fullness or pressure in the pelvic region.
- Light cervical discharge if a cyst happens to rupture.
- Discomfort during sexual intercourse.
- Occasional spotting between periods.
If you experience any of these, it is always worth a chat with your GP or gynaecologist, as noted in BMJ gynaecology resources.
Comparing Nabothian Cysts to Other Cervical Findings
It is helpful to see how these cysts compare to other common conditions identified during cervical cancer screening or routine exams.
| Feature | Nabothian Cyst | Cervical Polyp |
|---|---|---|
| What is it? | Mucus-filled gland | Overgrowth of cervical tissue |
| Benign? | Yes, always benign | Usually benign, rarely precancerous |
| Symptomatic? | Rarely | Often causes bleeding/discharge |
| Treatment | Rarely required | Usually surgical removal |
Diagnosis and Screening
Doctors usually spot these cysts during a routine pelvic examination. Using a vaginal speculum, the healthcare provider can visually inspect the cervix. Because they have a distinct appearance, a visual check is often all that is needed. You can find more about what to expect during these check-ups at Harvard Health.
If the appearance is slightly unusual, your doctor might utilise one of the following to be certain:
- Pap Smear: A standard Pap smear can rule out abnormal cell growth.
- Colposcopy: This involves using a magnifying instrument to look closer at the cervix. Learn more about this procedure via this Healthline resource.
- Biopsy: In very rare instances, a tiny sample of tissue is taken to ensure the growth isn’t something else.
Do You Need Treatment?
In most cases, the answer is a resounding “no.” Doctors typically recommend a “wait and see” approach because Nabothian cysts don’t pose a threat to your health. However, if a cyst is causing pain or is so large that it interferes with a regular Pap smear, your doctor might suggest a minor procedure.
Common removal methods include:
Electrocautery
This procedure uses a small probe with an electric current to generate heat and burn the cyst away. It is quick and generally performed in an outpatient setting. Medical details on this method are often found in medical overviews of cervical health.
Cryotherapy
As detailed by Johns Hopkins Medicine, cryotherapy involves using liquid nitrogen to freeze and destroy the cyst tissue. It is highly effective and requires very little recovery time.
The Bottom Line
While discovering a lump anywhere on your body can be frightening, Nabothian cysts are a perfectly normal variation of cervical anatomy. They are not cancerous, they don’t lead to cancer, and they usually don’t require any intervention. Keeping up with your regular cervical cancer screening as recommended by the WHO and Cancer Research UK is the best way to monitor your cervical health and ensure peace of mind.

Frequently Asked Questions (FAQs)
Can Nabothian cysts affect fertility?
No, these cysts do not typically affect your ability to get pregnant. They are located on the surface of the cervix and do not block the path of sperm or affect the health of the uterus. For more on reproductive health, see this patient guidance.
Are these cysts related to HPV?
No, Nabothian cysts are not caused by the Human Papillomavirus (HPV). They are caused by blocked glands, not viral infections. However, regular screening is still essential to monitor for HPV-related changes. General information on the virus can be found on WebMD’s nabothian cyst causes page.
Do they ever go away on their own?
Some cysts may rupture and disappear naturally, while others may stay the same size for years. Since they are harmless, there is no medical need to force them to go away unless they cause physical discomfort. You can read more about the cell biology research behind tissue repair at Nature.
