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.

Many of us who provide scientific information about HPV quadrivalent vaccine, also known as Gardasil (or Silgard in Europe), tend to focus on its effects on preventing cancers in women, so articles are inclined to pay attention to vaccinating teenage girls rather than boys. But, if you carefully analyze the disease, human papillomavirus, a sexually transmitted disease, its subtypes 16 and 18 not only cause approximately 70% of cervical cancers, but they cause most HPV-induced anal (95% linked to HPV), vulvar (50% linked), vaginal (65% linked), oropharyngeal (60% linked) and penile (35% linked) cancers. The viruses are generally passed through genital contact, almost always as a result of vaginal, oral and anal sex.
These HPV-related cancers can be prevented as long as you can prevent the HPV infection itself, either through never having genital contact with an infected person (and since about 79 million adult Americans are infected with the virus, that’s going to be difficult) or the HPV vaccine. The vaccine is a vitally important part of the war against HPV, it prevents the transmission of certain types (pdf) of human papillomavirus (HPV), specifically types 6, 11, 16 and 18. These subtypes of HPV are most often implicated in these cancers. Continue reading “The importance of the HPV vaccine to gay men”
Circumcision is one topic that certainly brings up more emotion than just about any medical procedure. In fact, the same level of rhetoric is used for and against circumcision that one hears with regards to vaccines, or even abortion. Recently, the city of San Francisco attempted to ban the practice, but a judge ruled that only the state could regulate medical procedures. During the summer, a German court banned circumcision for religious purposes, though a German court banning a Jewish practice must have blown up irony meters across the world.
In any discussion about circumcision, there is general consensus that female circumcision, or female genital mutilation, is an abhorrent non-medical procedure that is simply an anti-female procedure in many male-dominated societies. We’re not talking about that, and any comparison between male and female circumcision is a strawman argument. It is also clear that part of the anti-circumcision argument centers around secularism and atheism, because male circumcision is integral to both the practice ofJudaism and Islam. That is a valid argument, and there could even be a concern that unskilled individuals performing ritual circumcisions could cause serious complications. I personally could care less about religious rituals as long as they don’t harm anyone, so this is where we need to determine what the evidence tell us.
