Abstract

In recent 30 years, the global burden of cancer has become more serious, and one of social problem is population aging, plus declining birth rate, declining marriage rate and increasing divorce rate. Marriage is one of the most intimate and long-term social relations, and previous research had piecemeal reports of its impact on cancer morbidity and mortality without systematic review of evidence in high-quality population based epidemiological research. This paper summarizes the progress in research of the relationship between marital status and cancer to provide reference for future research and cancer prevention and control.
