Correct Answer: C. Advise HPV vaccine
The 14-year-old daughter of a cervical cancer patient should be advised HPV vaccination because cervical cancer is primarily caused by persistent infection with high-risk human papillomavirus (HPV), particularly types 16 and 18. This is NOT a hereditary genetic syndrome but an infectious disease preventable by vaccination. The daughter has not yet been exposed to HPV (at age 14, before sexual debut in most Indian populations) and is therefore an ideal candidate for primary prevention. The quadrivalent (HPV 6, 11, 16, 18) or nonavalent (HPV 6, 11, 16, 18, 31, 33, 45, 52, 58) vaccines are highly effective when given before HPV exposure. India's National Immunization Schedule recommends HPV vaccination for girls aged 9–14 years (preferably 9–13 years). The mother's cervical cancer does NOT increase the daughter's genetic risk; rather, it highlights the family's exposure risk to HPV and the critical importance of preventing infection in the next generation. This is a classic example of secondary prevention through vaccination in a high-risk family.
Why the other options are wrong
A. Screen for PTEN mutation — PTEN mutations are associated with Cowden syndrome (hamartoma syndrome), not cervical cancer. Cervical cancer arises from HPV-driven malignant transformation, not germline PTEN mutations. This option confuses hereditary cancer syndromes with infectious disease-driven malignancy. PTEN screening is irrelevant here. B. Screen for BRCA mutation — BRCA1/2 mutations predispose to breast and ovarian cancer, not cervical cancer. While the mother has cervical cancer, this does not indicate a BRCA-related familial cancer syndrome. Cervical cancer is HPV-driven, not BRCA-associated. This is a classic NBE trap pairing 'cancer in mother' with 'genetic screening' without considering the specific cancer type and its etiology. D. Perform cervical biopsy — Cervical biopsy is a diagnostic procedure for women with abnormal cytology or colposcopic findings, not a preventive measure for asymptomatic 14-year-olds. The daughter has no symptoms, no abnormal screening results, and is pre-exposure to HPV. Biopsy would be inappropriate, invasive, and offers no preventive benefit. This confuses diagnosis with prevention.
High-Yield Facts
- HPV vaccination is indicated for girls aged 9–14 years (preferably before sexual debut) per India's National Immunization Schedule; efficacy >90% when given pre-exposure.
- Cervical cancer is NOT hereditary; it is caused by persistent infection with high-risk HPV types (16, 18, 31, 33, 45, 52, 58), not germline mutations.
- Quadrivalent and nonavalent HPV vaccines protect against high-risk types 16 and 18 responsible for 70% of cervical cancers; nonavalent covers additional types for 90% protection.
- Family history of cervical cancer indicates HPV exposure risk in the family, making the uninfected daughter an ideal candidate for primary prevention, not genetic screening.
- Age 14 is optimal for HPV vaccination because most girls have not yet initiated sexual activity and are therefore HPV-naive; post-exposure vaccination is less effective.
Mnemonics
HPV-driven cancers: CERVIX Cervix (most common), Esophagus, Rectal, Vulva, Interdigital (skin warts), X (oropharynx). HPV causes these; vaccination prevents them in pre-exposure individuals. When to vaccinate: BEFORE Before sexual debut, Early adolescence (9–14 years), Full series (2–3 doses), Optimal response (>90% efficacy), Reduced effectiveness post-exposure, Even catch-up at 15–26 years (but less effective).
NBE Trap
NBE pairs 'mother with cancer' + 'daughter' to lure students into genetic screening (BRCA, PTEN) without considering that cervical cancer is infectious (HPV-driven), not hereditary. The trap exploits the reflex to screen relatives of cancer patients for germline mutations.
Clinical Pearl
In Indian clinical practice, a mother with cervical cancer is a powerful teachable moment to vaccinate her uninfected daughters—this single intervention prevents the next generation from acquiring HPV and developing cervical cancer, breaking the cycle of preventable disease in families with limited healthcare access.
