A University of Miami study analyzing over 4 million cancer cases revealed that adults who have never been married face a 68% higher risk of developing cancer in men and an 85% higher risk in women compared to those who are currently or have previously been married. Researchers suggest the correlation stems from complex social and lifestyle factors often associated with marital status, such as access to healthcare, social support networks, and health behaviors.

Why it matters

This research underscores the need for tailored cancer prevention strategies that take into account a patient's marital status. Healthcare providers should be mindful of this when discussing cancer screening and risk reduction with unmarried individuals, who may require more targeted outreach and education.

The details

The study, conducted by researchers at the University of Miami's Sylvester Comprehensive Cancer Center, found particularly pronounced differences in cancers linked to infections, such as cervical and anal cancer. This suggests the influence of partner-driven healthcare decisions and preventative measures. The data also revealed some cancers are more strongly linked to marital status than others, with never-married men having around five times the rate of anal cancer and never-married women experiencing nearly three times the rate of cervical cancer compared to their married counterparts.

  • The University of Miami study analyzed over 4 million cancer cases across 12 U.S. states.
  • The research findings were published on April 13, 2026.

What they’re saying

“It means that if you're not married, you should be paying extra attention to cancer risk factors, getting any screenings you may need, and staying up to date on health care.”

— Dr. Frank Penedo, Clinical Psychologist

What’s next

The study's findings highlight the importance of healthcare providers considering a patient's marital status when discussing cancer prevention and screening, to ensure unmarried individuals receive targeted outreach and education.

The takeaway

This research serves as a reminder that individuals who have never been married should be proactive about their health, prioritizing regular cancer screenings and preventative care, regardless of their relationship status. Early detection is key in fighting cancer, and unmarried adults may need to be more vigilant about their health due to the complex social and lifestyle factors associated with their marital status.
