Sir, the case to extend HPV vaccination to boys is well made in the recent correspondence from HPV Action (BDJ 2013; 215: 543). The number of people being diagnosed with oral cancer is on the rise, and the incidence is increasing in younger people, with a significant increase in patients under 45 years old over the last 20 years. There is increasing evidence to show that HPV plays a key role in the development of many of these cancers.

Dentists are well placed to identify oral cancers and early detection is key to ensuring the best patient outcomes. The British Dental Association (BDA) is one of a number of organisations to support a recent joint statement from the British Society for Oral Medicine (BSOM) and Cancer Research UK (CRUK) on ensuring mouth cancer is detected early to improve outcomes for patients. This statement encourages patients to have yearly examinations by a dentist and recommends people avoid tobacco and betel nut use, cut down on alcohol, eat at least five servings of fruit and vegetables a day and protect their lips with sunscreen. It also calls on the General Dental Council to consider making oral cancer a 'highly recommended' continuing professional development subject.

The BDA has publically called for an extension of the programme both for reasons of equality and on the basis that it will significantly improve overall immunity in the general population. Given the huge personal and economic costs of treating these cancers the case to extend HPV vaccination appears overwhelming.
