HPV is common and can spread through close sexual skin contact. Some types cause genital warts and others are linked with cancer. A bump cannot be safely identified as HPV from an online description or comparison photo alone.

01

What to know

  • Many HPV infections cause no symptoms and clear without causing health problems.
  • Condoms can lower risk but do not cover every area where HPV can spread.
  • In the United States, vaccination is recommended through age 26 if not adequately vaccinated; some adults ages 27 to 45 may decide with a clinician.
What people often get wrong

A similar-looking photo or one matching symptom cannot confirm a cause. Timing, change, examination, and sometimes testing matter.

02

Useful next steps

  • Ask a clinician to examine a new growth rather than using over-the-counter wart remover on genital skin.
  • Check your vaccination record and discuss whether vaccination applies to you.

When to get care

Do not rely on guesswork when the pattern changes.

  • Arrange care for new warts, unusual growths, lumps, sores, bleeding, or persistent skin changes.
  • A growing, ulcerated, or bleeding lesion needs prompt examination.

What a clinician may ask

  1. When did you first notice it, and is it changing?
  2. Is there pain, discharge, bleeding, fever, urinary change, or loss of function?
  3. Were there recent medicines, illness, injury, sexual contact, products, or procedures?
