Infection means — HPV: What Every Woman Needs to Know
Human papillomavirus (HPV) is the most common sexually transmitted infection worldwide. It is so prevalent that most sexually active adults will be exposed to HPV at some point in their lives — estimates suggest 80% lifetime exposure. In the vast majority of cases, the immune system clears the infection within two years without any symptoms, treatment, or lasting consequence.
But in a minority of women, certain high-risk HPV strains — particularly HPV 16 and HPV 18 — establish persistent infection in the cervical cells. This persistent infection drives the cellular changes that can, over many years, progress to cervical cancer. HPV is responsible for essentially 100% of cervical cancers and a significant proportion of vaginal, vulvar, anal, oropharyngeal, and penile cancers.
High-Risk vs Low-Risk HPV
- Low-risk types (HPV 6, 11) — cause genital warts (condylomata acuminata); rarely lead to cancer
- High-risk types (HPV 16, 18, 31, 33, 45, and others) — cause the cellular changes (CIN, VAIN, VIN) that precede cervical, vaginal, and vulvar cancer; no visible symptoms in most women
What a Positive HPV Test Means
A positive HPV test on a cervical smear or co-test is not a cancer diagnosis and should not cause panic. It means a high-risk HPV strain has been detected in cervical cells. The next step depends on whether cellular abnormalities (dyskaryosis) are also present. If the smear is normal but HPV-positive, a repeat test in 12 months is usually recommended. If abnormal cells are found alongside HPV, a colposcopy (examination of the cervix under magnification) is arranged.
Prevention: Vaccination and Screening
HPV vaccination (Gardasil-9 protects against 9 strains including HPV 16 and 18) is most effective when given before sexual activity begins — ideally at 9–14 years — but has proven benefit up to age 45 in clinical trials. Vaccination does not replace cervical screening; vaccinated women still require regular smear tests.
Cervical screening (Pap smear or HPV co-test) every 3–5 years from age 21–25 is the cornerstone of cervical cancer prevention. In India, uptake of cervical screening remains low — many cases of cervical cancer that I see at advanced stages could have been detected as CIN on a smear years earlier.

Consultation and Next Steps
For an individualised consultation on infection means, share your reports on WhatsApp at +91 76988 00333. Dr. Nishtha Tripathi Patel provides a detailed assessment within 24-48 hours and arranges in-person consultation at Sterling Hospitals, KD Hospital, or Welcare Speciality Hospital in Ahmedabad based on your location and treatment requirements.
Bring the following to your first consultation: imaging studies (ultrasound, CT or MRI on CD), histopathology and biopsy reports, tumour marker results (CA-125, HE4, CEA where relevant), a list of current medications, and any prior treatment summaries. For patients travelling from outside Ahmedabad, scheduling can be arranged to complete consultation and any pre-op work-up in the fewest possible visits.
If you are exploring second-opinion options, see our second-opinion service page. Independent review of diagnosis, staging, and proposed treatment plans is provided at no cost via WhatsApp report review. You do not need to switch hospitals to obtain a second opinion.
