Cervical cancer represents a global women's health issue. The emergence of vaccines against the most common types of human papillomaviruses causing cervical cancer represents a significant advance in cervical cancer prevention. Adolescent girls are the primary target population for vaccination-a population that traditionally has been difficult to reach. Obstetricians and gynecologists may hold the key to improving adolescent human papillomavirus vaccinations through the novel use of their existing relationships with adolescents' mothers during the routine cervical cancer screening visit. We propose using maternal cancer screenings, specifically breast and cervical cancer screening episodes, as "teachable moments," naturally occurring life or health events thought to motivate a person to adopt risk-reducing health behaviors spontaneously, to improve human papillomavirus vaccination rates among adolescents.
