CNN: What types of cancers are linked to HPV?

Wen: HPV is associated with a range of cancers in both men and women. In women, the most well-known is cervical cancer, but HPV can also cause cancers of the vagina and vulva. In men, HPV is linked to cancers of the penis, anus and the head and neck.

Over 90% of anal cancer is caused by HPV. Oropharyngeal cancer, also called throat cancer, is highly associated with HPV as well, with about 70% attributed to HPV. And more than 60% of penile cancer is caused by HPV.

CNN: Why has HPV vaccination historically been emphasized more for girls and women?

Wen: The initial focus of the HPV vaccine was driven by the clear and direct link between HPV and cervical cancer, which is a major global health issue. According to the World Health Organization, cervical cancer is the fourth most common cancer in women globally, causing more than 660,000 new cases and around 350,000 deaths in 2022.

Early clinical trials and public health campaigns prioritized preventing this specific cancer, so vaccination programs were first rolled out for girls. Over time, as more evidence accumulated about the burden of HPV-related disease in men, recommendations have expanded to include boys. However, public perception has lagged behind the science, and many people still think of this vaccine as primarily targeted for females.

This is so awesome that the word is getting out about the benefits for boys and men!! I remember hearing about the positive outcomes for boys and men quite a few years ago, mostly because of the throat cancer issue with HPV.

Everyone should get this vaccine! They upped the age limit to 45years old I think, so it's available for even more people now as well.
