Unfortunately, a lot of people think that sex education/abstinence is the answer for HPV, it's not. Safe sex, while good for many reasons does not prevent the transmission of HPV. HPV is transmitted by skin to skin contact, you do not have to have intercourse to contract HPV. As for the HPV vaccine in particular, unlike other vaccines which are developed by attentuating (reducing the strength of the organism that causes the disease) the causative agent this is not the case with Gardasil. It is made with VLP's (virus-like particles) contains no HPV DNA and therefore you cannot get the virus from the vaccine.
HPV is also shown to cause 25% of head/neck cancers and also 25% of lung cancers in addition to the typical warts on the hands and plantar warts on the feet.
A colonoscopy will not help with anal cancer. A high resolution anoscopy is what would be needed as this focuses specifically on the anal canal. Anal cancer and colorectal cancer are NOT the same. Many people think they are however anal cancer is typically squamous (arising from skin cells) while colorectal cancer is typically adenocarcinoma (arising from glandular cells). This is true of the cervix as well. The endocervix is typically squamous cell while lesions higher up in the cervical canal where the cell type changes is adenocarcinoma of the cervix. In situ (not yet invasive) of the cervix is known as AIS.
When my book comes out, it will shed the light you were referring to on not just anal cancer from HPV but all that HPV can cause and the entire gammut regarding dysplasias, grading, transmission, the vaccine, the stigma etc.
I'm glad my earlier post help to enlighten you regarding HPV.
