A growing study has suggested that getting married may offer more than emotional companionship - it could also play a significant role in long-term health. Research published in Cancer Research Communications highlights a striking connection between marital status and cancer risk, revealing that those who are single may face significantly higher rates of cancer compared to those who have ever been married. According to the study, never-married men have a 68 per cent higher cancer risk, while never-married women face an even steeper 83 per cent increase compared to married, divorced, or widowed individuals. These findings have sparked renewed interest in the relationship between marriage and health outcomes, particularly in the context of cancer prevention.Also

Why can marriage lower cancer risk?
According to experts, there are several factors that may explain this correlation. Since marriage has historically been almost universal, the now declining rates may mean fewer people benefit from its protective effects. One key factor, according to the scientists, is social support, as married people are more likely to have someone encouraging regular health checkups, cancer screenings, and early treatment. Paulo S. Pinheiro, the study’s lead author, emphasizes that unmarried individuals may be more socially isolated, making them less likely to engage in preventive care. Additionally, marriage is also associated with healthier lifestyle choices. Research shows married people are less likely to smoke, drink excessively, or engage in risky behaviours - factors strongly linked to cancers such as lung and cervical cancer.
Surprising gender findings
Interestingly, while previous research suggested men benefit more from marriage, this study indicates women may gain even greater protection. Brad Wilcox calls this finding “striking,” suggesting biological and reproductive factors could play a role. Scientists say women who have never given birth may have a higher risk of certain cancers, such as ovarian and endometrial cancer.
Cultural and racial insights
The study also found that Black men appear to benefit most from marriage, highlighting the importance of family support systems. Scientists say partners have a strong caregiving roles, who encourage early diagnosis and consistent care.
Is marriage the cause – or a marker?
Despite these findings, not all experts agree that marriage itself directly reduces cancer risk. Many argue that the benefits may reflect systemic advantages tied to marriage, like better access to health insurance and medical care. There is also a critical issue highlighted - bias in healthcare. Single patients may receive different treatment due to assumptions about a lack of support.
Support matters the most
Ultimately, experts do agree that social support - not marital status alone - is key. Whether through family, friends, or community networks, having people who provide emotional and practical support can significantly impact cancer outcomes. As marriage rates decline globally, researchers also suggest shifting the focus toward building strong support systems for everyone, regardless of relationship status. Encouraging regular screenings, reducing healthcare barriers, and challenging stereotypes about single individuals could help close the cancer risk gap. Marriage may offer protective health benefits, but meaningful support, marital or not, is what truly makes the difference in cancer prevention and care.
