HPV and Cancer in Ibero-America: What the Evidence Says About Spain and Latin America

October 6, 20266 min read

Human papillomavirus (HPV) does not recognize borders, but access to its prevention and diagnosis does. This review compares what scientific evidence shows in Spain, the rest of Europe, and Latin America —three realities connected by language and, in many cases, by migration, but with very different health gaps between them.

The finding that changes the question

A case-control study conducted in Spain and Colombia found something worth highlighting: HPV prevalence was nearly identical between both countries —42.6% in Spain and 41.7% in Colombia. This challenges a common assumption: it is not that Latin American women have greater biological exposure to the virus. The real difference lies elsewhere.

HPV — biological difference or access difference?

Spain vs. Colombia (case-control study)

HPV Prevalence42.6% vs. 41.7%
DifferenceNearly identical

Spanish vs. foreign-born women, Castilla y León screening program

HPV PrevalenceSpanish women: lower rate
DifferenceForeign-born: 23.51% (statistically significant difference, p<0.001)

Viral exposure is similar across populations; the real gap lies in access to screening, not biological risk.

Two different kinds of gap, not just one

Reviewing the evidence from both regions reveals a clear pattern: the nature of the access gap differs between Spain/Europe and Latin America.

In Spain and several European countries, screening systems generally exist and work well for the general population —Spain's cervical cancer incidence is among the lowest in the world (5.7 to 7.4 cases per 100,000 women). The gap appears in specific subgroups: migrants, those with short residence time, or those unfamiliar with the healthcare system. In several countries, such as France, even undocumented people have formal, free coverage for screening —the problem is not purely economic; it's about information, language, and trust in the system.

In Latin America, the gap is more structural: a shortage of trained laboratory staff, insufficient follow-up of positive results, and fragmented health systems in several countries. The result is a cervical cancer mortality rate nearly three times higher than in North America, with more than 80% of the Americas' cervical cancer burden concentrated in Latin America and the Caribbean.

Nature of the barrier — Spain/Europe vs. Latin America

Formal coverage for vulnerable populations

Spain / EuropeExists in several countries (e.g., France covers undocumented migrants at no cost)
Latin AmericaFragmented systems in several countries (Dominican Republic, Guatemala, Nicaragua)

Main barrier identified

Spain / EuropeLanguage, length of residence, unfamiliarity with the system, distrust
Latin AmericaShortage of trained staff, laboratories, follow-up of positive results

Urban-rural gap

Spain / EuropeDocumented but less dominant
Latin AmericaStrongly documented (Bolivia, Ecuador, Nicaragua, Peru, Trinidad and Tobago)

Mortality / regional burden

Spain / EuropeLow incidence in Spain (5.7-7.4 per 100,000)
Latin AmericaMortality ~3 times higher than North America; >80% of the Americas' cervical cancer burden

Self-collection: a solution already crossing borders

The same technological innovation —allowing patients to collect their own sample without a traditional gynecological exam— is advancing in parallel across very different contexts: the United States (with FDA approval for at-home use), Spain (already integrated into the official screening protocol in Extremadura), and Bolivia (where a peri-urban pilot reached in just three months the coverage that normally takes a year).

Latin American women in Spain: what the evidence still doesn't resolve

It's important to be honest about the limits of available knowledge here: studies don't agree with each other. A national survey found that Central and South American women in Spain had a screening probability similar to Spanish women. A later study found that Latin American women participated even less than African women. This isn't a contradiction to be artificially resolved —it reflects that the picture likely varies by autonomous community, study period, and local factors not yet fully understood.
