I keep making the same point over and over again, so I hope I don’t bore my regular readers. There are so few ways to actually prevent cancer, and one of the best is to prevent an HPV or human papillomavirus infection, with an underused vaccine. This simple vaccine can prevent so many cancers.
Genital and oral human papillomavirus (HPV) are the most common sexually transmitted infections (STI) in the USA. There are more than 150 strains or subtypes of HPV that can infect humans, although only 40 of these strains are linked to one or more cancers. HPV is generally transmitted from personal contact during vaginal, anal or oral sex.
Although the early symptoms of HPV infections aren’t serious, those infections are closely linked to many types of cancers in men and women. According to current medical research, here are some of the cancers that are linked to HPV:
These are all dangerous and disfiguring cancers that can be mostly prevented by the HPV cancer vaccine. HPV is believed to cause nearly 5% of all new cancers across the world, making it almost as dangerous as tobacco with respect to cancer.
The CDC (Centers for Disease Control and Prevention) just issued a report that examined human papillomavirus infection in Americans from 2011-2014. They found the following:
- During 2011–2014, prevalence of any oral human papillomavirus (HPV) for adults aged 18–69 was 7.3%; high-risk HPV was 4.0%.
- Overall, prevalence of any and high-risk oral HPV was lowest among non-Hispanic Asian adults; any oral HPV was highest among non-Hispanic black adults.
- Prevalence of any and high-risk oral HPV was higher in men than women except for high-risk HPV among Asian adults.
- During 2013–2014, prevalence of any and high-risk genital HPV for adults aged 18–59 was 45.2% and 25.1% in men and 39.9% and 20.4% in women, respectively.
- Prevalence of any and high-risk genital HPV was lower among non-Hispanic Asian and higher among non-Hispanic black than both non-Hispanic white and Hispanic men and women.
As I mentioned above, most strains of HPV are not related to cancer. However, according to this data, almost 23% of US adults, ages 18-59, had a type of HPV that increased the risk of certain cancers by a significant amount. Furthermore, around 42% of adults have any type of genital HPV.
An important aspect of this study is that it examined human papillomavirus infections in both men and women – previous studies on HPV concentrated on teen girls and younger women, which found a lower prevalence of the higher risk types of HPV. This ties closely to findings that certain HPV-related cancer rates have been increasing in the USA.
Again, the human papillomavirus infection is easily prevented by the HPV vaccine, called Gardasil. Unfortunately, the massive propaganda and myths against Gardasil, not based on any science and easily refuted, have done a lot to suppress the uptake of the anti-cancer vaccine.
I just hope these kind of studies impress people that the vaccine is an important tool in preventing some dangerous cancers. The HPV vaccine blocks HPV infections which can help prevent HPV-related cancers. Please get vaccinated – it might save your life.
Anecdotes are a fundamental part of the anti-vaccine propaganda machine. We have a tendency to overstate the importance of anecdotes, because they usually have an emotional appeal to them. Anecdotes are not data, not even close. At best, they are observations, but they give no indication of temporal correlation, let alone causality.
HPV vaccine anecdotes have become part of the discourse about Gardasil and other HPV vaccines. It has become full-time job just to debunk the myths that arise from a handful of anecdotes.
I have written on a number of articles about the HPV cancer-prevention vaccines, Gardasil, Cervarix and Silgard. These vaccines prevent infection by up to 9 different types of genital and oral human papillomavirus (HPV), the most common sexually transmitted infection (STI) in the USA.
The virus is generally transmitted from personal contact during vaginal, anal or oral sex. It is very easy to transmit, and according to the CDC, roughly 79 million Americans are infected with HPV–approximately 14 million Americans contract HPV every year.
HPV is believed to cause nearly 5% of all new cancers across the world, making it almost as dangerous with regards to cancer as tobacco. Most individuals don’t even know they have the infection until the onset of cancer. And about 27,000 HPV-related cancers are diagnosed in the USA every year.
There is a robust body of evidence supporting the fact that HPV vaccines are highly effective in preventing HPV infection. There are also several large studies (also, here and here) that strongly support the high degree of safety of the HPV vaccine.
Recently, the European Medicines Agency (EMA, European Union’s version of the US FDA) had started a review of human papilloma virus (HPV) vaccines “to further clarify aspects of their safety profile,” although the agency also points out that this review “does not question that the benefits of HPV vaccines outweigh their risks.”
The outcome? The EMA found that the HPV vaccine was safe.

The cancer preventing HPV vaccine, known as Gardasil, Silgard, or Cervarix, is one of the very few ways available to actually reduce the risk of certain cancers. The vaccine reliably blocks HPV infections, which are directly linked to several dangerous cancers such as cervical cancer.
Unfortunately, most boys in the United States aren’t receiving the cancer-preventing HPV vaccine according to a new survey of teen vaccination from the CDC. This low HPV vaccine uptake may result from the failure of physicians to recommend the vaccine or adequately explain its benefits to parents.
The HPV vaccine prevents cancer – this is not surprising information, because the wealth of evidence supporting the safety and effectiveness of the HPV vaccine is approaching unassailable. Of course, many people make claims about various cures for and prevention of cancer on the internet, but seriously there are just a handful of ways to prevent cancer. And one of them is getting the HPV vaccine.
Most of the early data was in reduction of cancer rates, especially for cervical cancer, in women. Part of this bias was because the HPV vaccine was originally just indicated for girls and young women. But more recently, the vaccine was approved in most areas of the world to be used with boys and young men.
However, a new study is out that gives us more evidence that the vaccine will prevent cancer in men. And that’s more good news if you’re looking for an effective way to prevent some cancers.

There are lots of quacks out on the internet that make all kinds of nonsense claims about how to prevent cancer. Eat blueberries. Eat kale. Eat GMO-free, organic blueberry kale soy sherbet.
I’ll bet there are thousands of claims made by charlatans to prevent cancer. But really, there are just a handful of ways to actually prevent cancer. Avoid tobacco smoke. Avoid the sun. Keep a healthy low weight. Avoid alcohol.
And get the HPV vaccine, known as Gardasil. Yes, Gardasil prevents cancer (actually, there are two, the other being the hepatitis B vaccine, but we’ll get to that in another article).
Now, there is even more evidence, from a huge research study, that supports the fact that Gardasil prevents cancer in young women.

Genital and oral human papillomavirus (HPV) is the most common sexually transmitted infection (STI) in the USA. There are more than 40 HPV sub-types that can infect the genital areas of males and females. Additionally, some HPV types, typically subtypes 16 and 18, can also infect the mouth and throat. HPV is generally transmitted from personal contact during vaginal, anal or oral sex. (For further information, please see my review of HPV vaccines.)

HPV quadrivalent cancer preventing vaccine, known as Gardasil (or Silgard in Europe), can reduce the risk of several types of cancer by blocking sexually transmitted (along with a few other pathways) infection by human papillomavirus (HPV). There are more than 40 HPV sub-types that can infect the genital areas of males and females. Additionally, some HPV types can also infect the mouth and throat. HPV is generally transmitted from personal contact during vaginal, anal or oral sex. About one-quarter of those sub-types are implicated in a number of genital, anal and oral cancers.
In a broad review of all of the published clinical research involving HPV vaccines, there is a clear scientific and medical consensus that HPV vaccines are extraordinarily safe, they quickly reduce HPV infection rates in populations of adolescents and young adults, and by reducing HPV infection rate, we will eventually have a real and statistically significant reduction in the risks of many types of cancer.
And as I’ve said many times, there are just a handful of methods, supported by real scientific evidence, to reduce the risk of cancer–quit smoking, lose weight to be clinical “skinny”, stay out of the sun, remove radon gas from your house, and get the HPV vaccine. No, eating a non-GMO, organic blueberry-kale shake will absolutely have NO effect on your risk of getting cancer, unless you find that so disgusting that you lose substantial weight.

The HPV quadrivalent vaccine, also known as Gardasil (or Silgard in Europe) prevents infection by the human papillomavirus, a sexually transmitted disease. The vaccine specifically targets subtypes 16 and 18, that cause not only approximately 70% of cervical cancers, but also they cause most HPV-induced anal (95% linked to HPV), vulvar (50% linked), vaginal (65% linked), oropharyngeal (60% linked) and penile (35% linked) cancers. It also targets HPV6 and HPV11, which account for approximately 90% of external genital warts. The viruses are generally passed through genital contact, almost always as a result of vaginal, oral and anal sex.
The HPV vaccine has been shown to be extraordinarily safe in two different and large epidemiological studies, one with over 700,000 doses and the other with over 350,000 doses. The absolute safety of the HPV vaccine is not in question except by those who engage in logical fallacies and anecdote.
In a recent study published in the journal Vaccine, researchers examined the HPV 16/18 infection rate in a randomized group of 4,178 young women, aged 16-24 years who were undergoing screening in community health services in the United Kingdom.
One of the key results was that in the group of 16-18 years, where the HPV infection rate dropped from 17.6% in a survey done prior to the introduction of the vaccine down to 6.6% post-vaccination. This group also showed the highest HPV immunization coverage, about 65%.
The authors concluded that:
[infobox icon=”quote-left”]These findings are the first indication that the national HPV immunisation programme is successfully preventing HPV 16/18 infection in sexually active young women in England. The reductions seen suggest, for the estimated coverage, high vaccine effectiveness and some herd-protection benefits.[/infobox]
These results mirror a study which established the substantial and dramatic drop in HPV infections after the release of the HPV vaccine in the United States. We can only conclude that the HPV vaccines caused a significant reduction in HPV incidence in UK and the USA. The HPV vaccine is effective.
The HPV vaccine is safe. The HPV vaccine prevents the HPV infection. And preventing HPV infections stop 60-95% of some serious and dangerous cancers and other annoyances such as penis pimples. Why is the decision to vaccinate with Gardasil even under discussion? Once again, here is scientific evidence that a vaccine saves lives.
