Which STI Looks Like Cauliflower? Genital Warts Explained

References UK clinical guidance from the NHS, the British HIV Association (BHIVA), and the British Association for Sexual Health and HIV (BASHH). Last updated: April 2026.

If you have cauliflower-shaped growths on your genitals, they’re almost certainly genital warts. Genital warts are caused by human papillomavirus (HPV), usually types 6 and 11. They’re one of the most common STIs in the UK and are treatable, though the virus itself can’t be cured.

What Do Genital Warts Look Like?

  • Flesh-coloured or slightly grey growths
  • Can be flat, raised, or have a rough, cauliflower-like texture
  • May appear as a single wart or in clusters
  • Size ranges from 1mm to several centimetres
  • Found on the penis, vulva, vagina, anus, upper thighs, or groin
  • Usually painless, though they may itch

Treatment

Genital warts are treated but HPV cannot be eliminated from the body. The immune system usually clears the virus within 1-2 years. Treatments include:

  • Warticon (podophyllotoxin) — applied at home, 3 days on, 4 days off
  • Aldara (imiquimod) — applied 3x weekly, boosts immune response
  • Condyline — podophyllotoxin solution
  • Clinical removal: freezing (cryotherapy), burning, or surgical excision

Recurrence after treatment is common (30-40%) because the virus persists in surrounding skin. Most people eventually clear HPV and stop getting warts.

Frequently Asked Questions

Are cauliflower bumps always genital warts?

In the genital area, cauliflower-textured growths are almost always HPV warts. Very rarely, other conditions (seborrhoeic keratoses, skin tags) can look similar. A sexual health clinician can diagnose visually.

Can genital warts turn into cancer?

The HPV strains causing warts (6 and 11) are low-risk and almost never cause cancer. High-risk HPV strains (16 and 18) cause cervical and other cancers but typically don’t cause visible warts. Having warts does not mean you’ll get cancer.
