Symptom Awareness & Evaluation

New Lump, Bump, or Ulcer on the Vulva

How doctors evaluate new lump, bump, or ulcer on the vulva — persistence, progression, common non-cancerous causes, and when to consult a doctor.

Quick Answer: What You Need to Know

This symptom is very common and is vastly more likely to be caused by a benign, non-cancerous condition. However, if it is persistent (lasting longer than 2 to 4 weeks) or progressive (getting steadily worse), you should have it evaluated by a healthcare professional.

🔍 How Doctors Evaluate This Symptom

Most symptoms are far more commonly caused by benign, non-cancerous conditions. When a change in your body is being assessed, two things matter most:

1Persistence

A new lump, wart-like bump, raw patch or ulcer on the vulva should be examined within a week or two, and an open sore that has lasted a month or more should be assessed without further delay — duration beyond a month is specifically flagged as a feature that needs looking at. A new pigmented spot that is changing in size, shape or colour should be examined promptly, whatever its duration.

2Progression

Progression means the lump enlarging, hardening or becoming fixed, an ulcer widening or failing to heal over weeks, bleeding or discharge from it, the surface becoming raw or cauliflower-like, colour changing or becoming irregular, pain or burning developing, or a lump appearing in the groin.

Common Non-Cancerous Causes (More Likely)

Common benign causes include Bartholin gland cysts and abscesses, epidermoid and sebaceous cysts, genital warts from HPV, herpes ulcers, folliculitis and boils, hidradenitis suppurativa, skin tags, and ingrown hairs after shaving or waxing. Aphthous ulcers and Behcet's disease also cause recurrent vulvar sores.

Representative Scenario: Evaluating New Lump, Bump, or Ulcer on the Vulva

An individual notices new lump, bump, or ulcer on the vulva and schedules an evaluation with their doctor to review their health history.

Common Non-Cancerous Causes

Before considering rare explanations, healthcare providers first check for common benign causes, such as:

When Cancer May Be Considered

Doctors consider cancer as a possibility primarily when a symptom is persistent (does not resolve after 2–4 weeks of standard care), progressive (steadily worsening), or accompanied by associated changes like unexplained weight loss, fever, night sweats, or a hard lump.

Details That Matter to Your Doctor

  • Exact date when you first noticed the change.
  • Whether the symptom is constant or comes and goes.
  • Whether anything makes the symptom better or worse.
  • Any family history of similar health conditions.

What NOT to Do

  • Do not repeatedly self-treat a persistent symptom with over-the-counter remedies without getting evaluated.
  • Do not attempt to self-diagnose using online images or automated symptom checking quizzes.
  • Do not assume a symptom is harmless simply because it is painless.
  • Do not delay emergency care if you experience severe shortness of breath or heavy bleeding.

What a Clinician May Ask or Examine

Your doctor will take a medical history, perform a physical exam, review medications, and order targeted blood work or imaging scans if needed to clarify the cause.
