Session type:

Infection with viruses or bacteria has been implicated in the pathogenesis of a range of different cancers accounting for an estimated 2 million new cases per year. A common feature of these cancers is that they involve chronic or persistent infections that are widespread in the normal population with tumours only developing in a small proportion of infected people, usually many years after initial infection. This session will review the epidemiology of infection-associated cancers and then consider the mechanisms underlying tumour pathogenesis as exemplified by examples from the two main classes of infectious agent.
