Oral cancer cases are rising, with 6,200 this year, figures from Cancer study UK show, by means of two-thirds of cases in men. But high-risk strains of HPV are connected to oral cancers, as healthy as cervical and further genital cancers. Oral cancers usually take at least a decade to develop.
Smoking rates have fallen significantly, though it is still the major cause of oral cancers. Alcohol is another. CRUK says that, while overall consumption has fallen compared with 10 years ago, it could be that some groups are drinking more. According to experts warning signs included mouth ulcers and red or white patches in the mouth that would not heal.
