A surprising study finds that marital status is an overlooked ‘social determinant’ of cancer, finding that people who have never been married are at significantly greater risk of developing the disease.
In terms of incidence rates, research shows that compared to those who are married or have ever been married, never-married men face a 68% higher incidence of cancer, while never-married women face an 85% higher rate. This association is strongest among those aged 55 and older, suggesting that the effects of social factors accumulate across the lifespan. Although overall rates are higher for those who have never married, certain cancers show even more dramatic differences; Thus, the high cancer rates in this group likely reflect variations in HPV exposure.
In this regard, Frank Penedo of the University of Miami, co-author of the study, said: “It means that if you are not married, you should pay extra attention to the risk factors for cancer, get all the tests you need, and stay abreast of the latest developments in healthcare.”
It is pertinent to note that marriage has long been associated with better health outcomes, including lower morbidity, higher self-rated health, and longer life expectancy.
Positive factors associated with marriage include increased social support, healthier behaviors such as reduced alcohol and tobacco use, and greater economic stability. Spouses often encourage each other to attend screenings and stay informed about health care. Previous studies show that married patients tend to be diagnosed at an earlier stage and experience a higher survival rate.
These benefits are often attributed to supporting spouses in promoting screening, assisting with treatment, and navigating complex care. However, researchers made it clear that people should not get married just to prevent cancer. For those who are not married, the study suggests paying extra attention to cancer risk factors, prioritizing regular screenings and staying proactive with health care.
