Marriage Linked to Lower Cancer Risk
19 Apr
Summary
- Never-married men 70% more likely to get cancer.
- Never-married women 85% more likely to get cancer.
- Married individuals may have better healthcare access.

A comprehensive analysis of over 4 million adults across 12 US states has revealed a notable correlation between marital status and cancer risk. Individuals who have ever been married demonstrated significantly lower rates of cancer diagnoses compared to those who have never married. Specifically, never-married men faced a 70% higher risk, and never-married women an 85% higher risk of developing cancer.
The study highlights disparities in certain cancer types. For instance, never-married men had five times the rate of anal cancer, and never-married women nearly three times the rate of cervical cancer, both linked to HPV. Researchers suggest that married individuals may be more inclined to utilize preventive tools like vaccinations and screenings, potentially due to increased social support encouraging healthcare appointments. Cancers like endometrial and ovarian were also more common in never-married women, possibly linked to childbearing history.
While the findings are substantial, researchers caution against attributing the lower risk solely to marriage itself. They emphasize that healthier, wealthier, and better-supported individuals may be more likely to marry. Factors such as mental illness, addiction, chronic illness, or poverty can hinder marriage and are also linked to higher cancer risks. The study underscores the importance of social support, access to healthcare, and preventative encouragement for everyone, regardless of marital status.
