The National Health Service Cervical Screening Programme (NHSCSP) guidelines raised the initiation of screening age from 20 to 25 years of age in 2004, on the basis that only 1.3% of cervical cancers occur in this age group. Between 2003 and 2005, cervical cancer was diagnosed in six women under 25 years in East Kent, 6.25% of 96 cervical cancers cases. All except one patient in our series presented with a cervical smear abnormality. High-grade cervical smear abnormalities were identified and treated in 187 women under 25 years during this period. Adoption of the guidelines may increase the incidence of invasive disease in young women, the stage at diagnosis and radicality of treatment required.
