Hello - the Oral Sex Safe show supposedly set out to find out why the stats for HPV related cancers are rising?? Did she check out who funds the research? There are two main companies competing for government contracts to vaccinate people against HPV - that's one hell of a lot of business - HPV does not cause all cervical cancers, so whilst screening picks them all up, vaccination doesn't.. so having vaccination won't protect you against cervical cancer - so screens are essential - and they will pick up HPV cervical cancers, and genital warts anyway.
The campaign by these companies to get the vaccination for girls has been successful. Soon afterwards the same companies were talking about oral cancers (when previously they were talking only about cervical cancers) because they are looking for the second half of the market. A tiny tiny amount of oral cancers only caused by HPV - there is normally other major risk factors - spirits drinking, smoking etc.
Journalists are now being pumped with oral cancer scare stories (when oral cancer is pretty small risk - even more so if HPV is vaccinated against in girls), in order to get a campaign going to try to vaccinate men too.
Another big contract that won't significantly affect the likelihood of catching or curing oral cancers.
