Public not always made aware of these potential cancer preventing drugs. Most PCP depend upon the pharm companies to keep them inform so if they don't know, we aren't told and if the pharm companies don't spend the advertising $'s. Heck even if they do (Gardasil) response can be dictated by other issues like religion or politics.

Today something is touted as medically good for us and tomorrow it's medically bad for us so why listen?

Human nature, even if we are told to do something we just refuse to do it.

The good and the bad...in our political quest to protect us from false medical claims we also have made it sometimes impossible to bring something to the public that is beneficial? The FDA won't approve the Gardasil vaccine for say oral cancer unless they have a study that would take decades to prove even though logic says if you have a vaccine that effectively kills 100% of HPV 16 and we know that HPV 16 is linked to a large % of SCC in the oral cavity, then it doesn't take a brain scientist to conclude that eliminating HPV 16 will therefore eliminate THAT cancer.
