HPV Types And Cancer Risk

  • HPV has many types: low-risk (e.g., 6,11 cause genital warts) and high-risk (about 15 types can cause cervical cancer).
  • HPV 16 and 18 cause ~75% of cervical cancers, making HPV testing crucial.
ADVICE

Follow Age-Based Screening Rules

  • Start screening at age 21 or three years after first intercourse, and follow guideline intervals: every three years for low-risk patients.
  • From 30–65 add HPV testing with the pap because pap alone has limited sensitivity.
ADVICE

Act Quickly On High-Risk HPV Results

  • If pap is normal but high-risk HPV non-16/18 is positive, repeat testing at 6 and 12 months and watch for clearance.
  • If HPV 16 or 18 is positive, go straight to diagnostic colposcopy even with a negative pap.
