Dr Mark Porter explores health issues of the day.
He is joined by Dr Anne Szarewski to discuss HPV, a family of viruses that cause verrucas, warts and cervical cancer. The majority of the infections clear up without any treatment but some are more serious.
A vaccine will soon be available for all girls aged 11-18 to prevent the two viruses that cause the majority of cervical cancers. Since these viruses are sexually transmitted, the aim is to vaccinate before girls become sexually active.
