Objective:

To analyze the relationship between marital status and cancer incidence across various demographics in the United States, emphasizing the role of marital status in cancer risk frameworks.

Approach:

Key Findings:

• Never-married adults had significantly higher cancer incidence than ever-married individuals across nearly all major cancer sites, racial and ethnic groups, and age categories.
• Cancer incidence was 68% higher in never-married men and 83% higher in never-married women.
• The highest cancer incidence rate was observed in never-married Black men at 1,600.6 per 100,000.
• Site-specific differences were notable, with IRRs of 5.04 for anal cancer in men and 2.64 for cervical cancer in women.
• Disparities were most pronounced among Black men, with lower incidence in ever-married Black men compared to White men.

Interpretation:

Marital status may serve as a social exposure that reflects cancer risk factors not fully explained by race, age, or socioeconomic status, highlighting its importance in cancer risk assessments.

Limitations:

• Legal marital status does not account for cohabitation, relationship quality, or sexual orientation.
• Individual-level data on income, parity, smoking, and diet were not available.
• The study's findings are associational and do not establish causation.

Conclusion:

Incorporating marital status into cancer surveillance may help identify at-risk populations more accurately, reflecting cumulative behavioral and social exposures.
