Human papillomavirus (HPV) is one of the most common viruses that can cause cancer, and it has been linked to malignancy in more than six areas of the human body. Twelve HPV strains are associated with cancers in both men and women, including throat, anal, penile, cervical, vaginal, and vulvar cancer, according to the World Health Organization.
The HPV vaccine has been outstandingly effective in preventing cervical cancer and improving patients’ lives—and there are still significant gains on the horizon for administrative and clinical leaders who understand the dynamics of the disease and vaccine.
Victories in cancer prevention—The benefits of HPV vaccination
In 2022, more than 830,000 cancer cases and 420,000 deaths were attributable to HPV infection. HPV is believed to be responsible for the following percentages of cancers in these body parts in the US:- Cervix: 91%
- Anus: 91%
- Vagina: 75%
- Oropharynx: 70%
- Vulva: 69%
- Penis: 63%
The most common type of cancer caused by HPV, cervical cancer, was a leading cause of death among women in the US. Wider use of Pap tests, HPV screening, and the HPV vaccine have helped decrease the rate of HPV infections and genital warts by 88%. Among women between ages 20 and 24 (the first patients to receive the vaccine after its introduction in 2006) cervical cancer rates dropped 65% between 2012 and 2019. Researchers in Scotland have discovered that women vaccinated at 12-13 years old retained high rates of protection against serious cervical precancerous legions.
Understanding the HPV vaccine and cancer prevention
Genital HPV is the most common sexually transmitted infection in the US, having the ability to infect both men and women. In most cases of HPV, the immune system clears the virus within two years. But in some cases, the body isn’t able to get rid of the infection. In cancer-causing infections, it can linger and turn normal cells into abnormal ones, which can then become cancer.
Cancers caused by HPV infection have become highly preventable, largely thanks to clinical leaders' efforts in improving screening and vaccine uptake — over 90% of infections are preventable, according to CDC. An increase in vaccine uptake has the potential benefits of reduced cancer risk, improved sexual health and overall well-being, and better quality of life for patients and communities.
