Cervical Ectropion: Symptoms, Causes & When to See a UK Online Doctor

Cervical ectropion, also sometimes referred to as cervical erosion, is a common condition affecting the cervix—the lower part of the womb that opens into the vagina. Despite the term 'erosion', the tissue is not actually eroding or wearing away. Instead, the soft 'glandular' cells that usually line the inside of the cervical canal (the endocervix) spread to the outer surface of the cervix (the ectocervix).

These glandular cells are more delicate and contain more blood vessels than the harder 'squamous' cells that usually cover the outer cervix. Because these cells are fragile, they can bleed easily when touched or irritated, leading to symptoms like spotting. In the UK, it is estimated that a significant proportion of women will experience ectropion at some point, particularly during their reproductive years.

Is it the same as cervical cancer?

It is important to clarify that cervical ectropion is not a precursor to cancer. It does not increase your risk of developing cervical cancer. However, because the symptoms—specifically abnormal bleeding—can overlap with more serious conditions, it is vital to have any new bleeding investigated by a healthcare professional to rule out other causes.

Many women with cervical ectropion have no symptoms at all and only discover they have it during a routine cervical screening (smear test). However, when symptoms do occur, they typically include:

• Postcoital bleeding: Bleeding or spotting immediately after sexual intercourse.
• Intermenstrual spotting: Light bleeding between your scheduled periods.
• Increased vaginal discharge: A clear or white discharge that is not associated with an unpleasant odour or itching.
• Pain during or after sex: Though less common, some women report a dull ache or discomfort.

The bleeding is usually 'spotting' rather than a heavy flow. Because the glandular cells are sensitive to changes in pH and physical contact, activities like exercise or even a simple pelvic exam can sometimes trigger light bleeding. NICE guidance suggests that while these symptoms are often benign, they must be clinically assessed to ensure they are not related to infection or other cervical pathology.

The primary driver of cervical ectropion is the hormone oestrogen. Oestrogen levels fluctuate throughout a woman's life, and high levels of this hormone cause the cervix to change, allowing those internal glandular cells to move outwards. This is why the condition is most common in:

• Women on the combined contraceptive pill: The oestrogen in the pill mimic's the body's natural cycle but can keep levels high enough to maintain an ectropion.
• Pregnant women: Pregnancy causes a massive surge in oestrogen, making ectropion very common during this time.
• Teenagers: During puberty, the body undergoes rapid hormonal shifts which can lead to the development of an ectropion.

Conversely, cervical ectropion is rarely seen in postmenopausal women because oestrogen levels drop significantly during and after the menopause. If you are postmenopausal and experience vaginal bleeding, this is never considered 'normal' and requires urgent medical review.

Cervical ectropion is usually diagnosed via a speculum examination, similar to the process for a smear test. A GP or nurse will look at the cervix; an ectropion typically looks like a red, velvety patch around the opening of the cervix (the os).

If you are due for your NHS Cervical Screening, the clinician will likely perform the test at the same time. If your smear test is up to date and you have a low risk of STIs, the visual confirmation of an ectropion is often enough for a diagnosis. If there is any doubt or if the cervix looks 'suspicious' in a way that doesn't match a standard ectropion, you might be referred for a colposcopy—a more detailed look at the cervix using a magnifying instrument.

In the vast majority of cases, no treatment is required for cervical ectropion. If the symptoms are not bothering you, the best approach is often to leave it alone, as it frequently resolves itself over time or when oestrogen levels drop (for example, if you stop taking the contraceptive pill).

However, if bleeding is frequent, heavy, or causing significant distress, your GP may suggest treatment to 'cauterise' the area. This involves removing the glandular cells from the surface so they can be replaced by normal, tougher skin cells. Common methods include:

• Cold coagulation: Using a heat probe to seal the area (despite the name, it uses heat).
• Cryotherapy: Freezing the affected cells.
• Silver Nitrate: A chemical applied to the cervix to seal the tiny blood vessels during a simple exam.

Following treatment, you may have some watery discharge or light bleeding for a few weeks while the cervix heals. Doctors usually advise avoiding internal tampons and sexual intercourse for up to four weeks after the procedure to prevent infection.

If you have noticed spotting after sex or between your periods, it is natural to feel anxious. While cervical ectropion is harmless, abnormal bleeding is a symptom that should always be discussed with a medical professional. You can speak to a GP online to discuss your symptoms and history in a calm, private environment.

An online GP consultation can help determine if your symptoms are likely related to your contraception or if you need to be referred for a physical examination. If you are concerned about your hormonal contraception causing these symptoms, our clinicians can discuss alternative options, such as progestogen-only methods, which may reduce the oestrogen levels causing the ectropion. While an online doctor cannot perform a physical cervical exam, they can provide a referral for a smear test, provide sick notes if you are recovering from a procedure, or guide you through the next steps in the UK healthcare system.
