The human papillomavirus (HPV) is often discussed as a sexually transmitted infection, but its impact extends far beyond that categorization. Increasingly, medical experts are highlighting the virus’s potential to cause cancers in both men and women, affecting up to six different body areas. Recent data and ongoing public health campaigns are emphasizing the importance of both universal vaccination and robust screening programs as crucial tools in preventing HPV-related diseases and cancers.
On March 2, 2026, experts gathered to discuss the evolving understanding of HPV and the strategies needed to combat its widespread prevalence. The discussion included Noelia López, Director of Medical Affairs, Vaccines and Immunology at MSD in Spain. Dr. Jesús de la Fuente, a gynecologist and coordinator at the HU Infanta Leonor Vallecas-Madrid; Dr. Esther Redondo, Head of the Technical Unit for Vaccination and International Health at Madrid Salud; and Dr. Valero Sebastián, Head of the Vaccination and Systematic Immunization Service at the Public Health Directorate of the Valencian Community. Their collective expertise underscored the urgency of addressing this common infection, which is responsible for approximately 4.5% of all tumors globally according to MSD.
Understanding the Scope of HPV Infection
HPV is the most common sexually transmitted infection worldwide. However, it’s crucial to understand that HPV isn’t a single virus, but rather a family of over 100 related viruses. Some types cause warts, while others can lead to various cancers. The virus can remain dormant for years, even decades, before manifesting as a health problem, making regular screening and preventative measures all the more important. As Dr. Jesús de la Fuente explained in a recent interview, at least 2.5 million people in Spain receive an HPV diagnosis each year as reported by Onda Cero.
The impact of HPV extends beyond physical health, carrying significant emotional and social consequences for those affected. The “Write Your Own Story” campaign, supported by 71 socio-health organizations, aims to raise awareness about HPV and emphasize the importance of prevention. This year, MSD is collaborating with the Spanish women’s national football team with the campaign “Acquire Informed About HPV: The Best Play,” combining sports and health to promote awareness.
Cancers Linked to HPV: Beyond Cervical Cancer
While cervical cancer is the most well-known HPV-related cancer, the virus can likewise cause cancers in other areas of the body. These include:
- Anal Cancer: HPV is a major cause of anal cancer, particularly in individuals with weakened immune systems.
- Oropharyngeal Cancer (Throat, Tongue, and Tonsils): The incidence of oropharyngeal cancer linked to HPV is rising, especially among men.
- Penile Cancer: HPV infection is associated with a significant proportion of penile cancers.
- Vulvar Cancer: HPV is a contributing factor in the development of vulvar cancer.
- Vaginal Cancer: Similar to cervical cancer, HPV plays a role in the development of vaginal cancer.
Dr. De la Fuente emphasized that the virus can cause cancer in up to six different body locations in both men and women according to his statements to Onda Cero. He specifically noted the difficulty in detecting early signs of cancer in the throat, making vaccination even more critical in preventing these cases.
The Power of Vaccination and Screening
Vaccination remains the most effective way to prevent HPV infection and the cancers it can cause. The HPV vaccine is most effective when administered before the onset of sexual activity, providing the highest level of protection. Public health initiatives are increasingly focused on adolescent vaccination programs, aiming to protect young people before they are exposed to the virus. The vaccine protects against the most common high-risk HPV types, including type 16, which is particularly dangerous.
Screening programs, such as Pap tests and HPV tests for cervical cancer, are also vital for early detection and prevention. Regular screenings can identify precancerous changes in the cervix, allowing for timely treatment and preventing the development of cancer. The Spanish Ministry of Health provides information on HPV vaccines and screening programs for healthcare professionals as detailed by MSD.
Vaccination Strategies and Evolving Recommendations
Current vaccination strategies prioritize adolescents, but expanding vaccination efforts to include older age groups is also being considered. While the vaccine is most effective before sexual activity, it can still provide benefit to individuals who have already been exposed to HPV. The long-term impact of widespread vaccination on HPV-related cancer rates is still being studied, but early data are promising.
Maintaining stable sexual relationships can reduce the risk of HPV transmission, but it does not eliminate it entirely. The virus can persist for years without causing symptoms, making it difficult to detect and prevent its spread. This underscores the importance of vaccination and regular screening for all sexually active individuals.
Looking Ahead: Continued Research and Public Health Efforts
Ongoing research is focused on developing more effective HPV vaccines and improving screening methods. Scientists are also investigating the role of the immune system in controlling HPV infection and developing potential therapies for HPV-related cancers. Continued public health education and awareness campaigns are essential to ensure that individuals are informed about the risks of HPV and the benefits of prevention.
The fight against HPV requires a multi-faceted approach, combining vaccination, screening, and education. By prioritizing these strategies, we can significantly reduce the burden of HPV-related diseases and cancers, protecting the health and well-being of individuals worldwide.
The next key development to watch will be the release of updated vaccination guidelines from the Spanish Ministry of Health, expected in late 2026.
