Finding a lump on or around your vagina can be terrifying — especially when your mind goes straight to the worst-case scenario. In most cases, it isn’t cancer. But it does need to be checked.

Here are the 7 most common causes — and the signs that mean you need to be seen today.

Watch First: 7 Reasons to Pay Attention to Vulval and Vaginal Lumps

First: Know Your Anatomy

The words “vaginal lump” and “vulval lump” are often used interchangeably, but they’re different areas. The vulva is the external area — labia, clitoris, vaginal opening. The vagina is the internal canal. Most lumps women notice are actually on the vulva, not inside the vagina. This matters because the causes — and how they’re treated — can differ.

The 7 Most Common Causes

1. Bartholin’s Cyst

The Bartholin’s glands sit on either side of the vaginal opening and produce lubrication during sex. When the duct becomes blocked, fluid builds up and forms a cyst — typically felt as a smooth, round lump, usually painless unless it becomes infected.

If it’s infected (Bartholin’s abscess): You’ll know. It becomes swollen, hot, very painful, and may make sitting or walking uncomfortable. This needs same-day GP attention — it won’t resolve without treatment.

Treatment: Small, painless cysts are often monitored. Infected cysts require drainage — usually done in a minor surgery clinic or A&E.

2. Genital Warts

Caused by certain strains of human papillomavirus (HPV), genital warts appear as small, flesh-coloured bumps — sometimes flat, sometimes raised and cauliflower-like. They’re not painful in most cases. They’re the most common STI in the UK.

Important: Genital warts are caused by different HPV strains to those that cause cervical cancer. Warts themselves are not a cancer risk. But you do need treatment, as they can spread to partners and won’t always clear on their own.

Treatment: Topical creams (Podophyllotoxin, Imiquimod) or clinic-based treatment (cryotherapy/freezing). Go to your GP or a sexual health clinic — not a pharmacist.

3. Genital Herpes

Herpes (HSV) causes painful, fluid-filled blisters that can appear on the vulva, vagina, cervix, thighs, or buttocks. The first outbreak is usually the worst — blisters, pain, flu-like symptoms. Subsequent outbreaks tend to be milder and shorter.

Key fact: Herpes has no cure, but it is very manageable with antiviral medication. Many people live for years without symptoms. A diagnosis is not the end of the world — it just requires honest conversations and some practical steps.

Treatment: Antiviral tablets (aciclovir, valaciclovir). Available from your GP or sexual health clinic.

4. Ingrown Hair

The most common — and least alarming — cause of a small vulval lump. Caused by hair curling back into the skin, particularly after shaving or waxing. It appears as a small, red, sometimes pus-filled bump.

Do NOT squeeze it — this can cause infection. Warm compresses usually resolve it within a week. If it doesn’t, or if the area becomes significantly swollen or hot, see your GP.

5. Cystocele (Bladder Prolapse)

A cystocele happens when the bladder pushes against the front wall of the vagina, creating a soft bulge at the vaginal opening — often described as “feeling something coming down.” It’s more common after childbirth or as we age.

Symptoms: A dragging sensation in the pelvis, feeling of pressure, difficulty emptying the bladder fully, or leaking urine when you cough or sneeze.

Treatment: Pelvic floor physiotherapy is the first-line treatment. A ring pessary (a device inserted by your GP) can provide support without surgery. Surgery is available for more severe cases.

6. Pimples and Acne

The skin of the vulva contains hair follicles and sweat glands — so yes, it can get spots. These look and behave just like acne elsewhere: small, red, sometimes with a white head. Common triggers include tight clothing, sweat, and friction.

Usually resolves on its own. Keep the area clean and dry. Avoid tight synthetic underwear. If spots are recurring, persistent, or unusually large, see your GP to rule out other causes.

7. Vulval Cancer

This is the one everyone fears — and it is real, which is why these lumps should never just be ignored and hoped away. Vulval cancer accounts for around 1,300 new cases in the UK each year. The average age of diagnosis is over 65, but it can occur at any age.

It does NOT look like a typical lump. It may appear as a persistent sore or ulcer that doesn’t heal, a thickened or raised patch of skin (white, red, or dark), or a wart-like growth. It’s almost always accompanied by other symptoms: persistent itching, burning, or pain.

If you notice any of these — a sore that won’t heal, persistent unexplained itching, or skin changes on the vulva — see your GP and ask to be examined. Early diagnosis makes an enormous difference.

When to See Your GP — The Clear Rules

General rule: if it’s been there more than 2–3 weeks and you don’t know what it is — get it checked. Most things are benign. But the ones that aren’t need early attention.

The Bottom Line

Most vaginal lumps are not cancer. But “probably fine” is not a diagnosis. Know the 7 causes, know the red flags, and know that your GP is there to examine — not to judge.

You searched for this because something felt wrong. Trust that instinct and get it checked.
