HPV

Researchers estimate that close to one in eight cancer cases worldwide are caused directly by infectious pathogens, chiefly human papillomavirus, Helicobacter pylori, and hepatitis B and C viruses. The figure is drawing attention because many of these cancers are preventable through vaccination, screening, and antimicrobial treatment, making infection-related cancer a major global public health opportunity.

New coverage highlights that roughly one in eight cancers worldwide are caused by infections. Reports point to common pathogens — with one culprit reportedly surpassing HPV as the biggest contributor — and stress that many of these cancers are preventable through vaccination, screening and treating infections such as HPV, hepatitis B and C, and H. pylori. Doctors are urging the public to learn the risks and simple protective steps.

A new analysis reported by Gizmodo finds that roughly one in eight cancer cases worldwide are linked to infections, with viruses and bacteria other than HPV accounting for the largest share. People are discussing which pathogens drive these cancers and how vaccination or treatment could prevent a significant portion of cases globally.

A new report indicates that roughly one in eight cancers worldwide can be traced back to infections. Contrary to common assumptions, the leading infectious cause is not HPV but another pathogen, with viruses and bacteria together accounting for a significant share of global cancer cases. The finding highlights how preventable infections remain a major, underappreciated cancer risk.

Researchers at Yale School of Medicine report progress in cultivating human papillomavirus in laboratory conditions, a longstanding challenge in virology. Being able to grow HPV reliably could improve how vaccines are developed and tested, potentially supporting better prevention of HPV-related cancers. The work highlights continued efforts to refine vaccine technology against a common sexually transmitted infection.
