I grew up with parents in a constant fight, and in a marriage myself know that the day to day isn’t always easy. But if being stressed about getting married is a question in your court, the research is in favor of tying the knot for a healthier, longer life. A large new analysis of more than 4 million cancer cases is raising eyebrows towards conservative values, with a striking finding: people who have never been married appear significantly more likely to develop cancer than those who are or have been married.
According to the research from the University of Miami, cancer risk was 68% higher in never-married men and 85% higher in never-married women.
At first glance, the conclusion seems simple that wearing a wedding ring protects your health. But scientists are also pushing back on the conclusion. Being married, they suggest, may reflect a cluster of lifestyle and social factors that influence long-term health. This lifestyle could be repeated with the non-married people. And what happens if you get a divorce?
Researchers point to differences in behavior. People who are married they say on average, less likely to smoke, more likely to seek medical care, and more likely to go for routine screenings. They may also experience more stable daily routines and emotional support, factors that can reduce chronic stress, which is increasingly linked to disease risk.
For women, reproductive history may also play a role. Having children, something more common among married individuals in many populations, can influence the risk of certain cancers, including breast and ovarian cancer especially if they breast feed.
Clinical psychologist Frank Penedo, one of the researchers involved, emphasizes that the takeaway isn’t about relationship status, it’s about awareness. “If you’re not married,” he says, “you should be paying extra attention to cancer risk factors, getting any screenings you may need, and staying up to date on health care.”
Friends could create cancer-support nodes for screening, recovery and post-care.
That advice applies broadly. You may not have someone on you about regular checkups, healthy eating, exercise, avoiding tobacco, and managing stress. So you should be aware of these co-factors to cancer, regardless if someone is married, single, divorced, or widowed.
The findings also highlight something deeper: the role of social connection in health. Humans are social beings, and strong support systems, whether through partners, friends, or community, can influence how people take care of themselves and respond to illness “It’s a clear and powerful signal that some individuals are at a greater risk,”says Penedo.
Other studies have found that singleness comes with its own benefits, including more close relationships and greater opportunities for personal growth, so, as always, the research needs to be put in context.
There has also been evidence that marriage has its downsides – with a higher risk of dementia attached, for example. It’s not simply that marital status, one way or the other, is the healthier option.
