Which of the following is considered the most effective preventive measure against cervical cancer?

• A. Routine Pap tests
• B. Colposcopy
• C. Human papillomavirus (HPV) vaccine
• D. Laser treatment for genital herpes

Answer: (C)

The main idea is preventing cervical cancer by stopping the infection that causes it. The HPV vaccine provides the strongest form of prevention because it trains the immune system to neutralize the high‑risk human papillomavirus types most often linked to cervical cancer, especially HPV types 16 and 18. By preventing infection with these viruses before exposure, the vaccine lowers the chances of developing cervical precancers and, later, cancer.

Pap tests and colposcopy are important parts of cervical cancer control, but they are about detection and follow-up after infection or abnormal changes have occurred, not about preventing the initial infection. A laser treatment for genital herpes isn’t related to preventing cervical cancer.

Even with vaccination, ongoing cervical cancer screening is still important for those who weren’t vaccinated or who may have exposures to other HPV types not covered by the vaccine. Vaccination is most effective when given before any exposure to HPV, typically in preteen years.
