Study: Marital Status Linked to Cancer Rates

A comprehensive study involving over four million cancer cases in the US revealed a significant link between marital status and cancer risk. Between 2015 and 2022, researchers observed substantially higher cancer incidence rates among adults who have never been married, compared to their married or previously married counterparts. Specifically, never-married men showed a 68% higher cancer incidence, while never-married women had an 85% higher rate.

The scientists emphasize that marriage itself is not a protective factor. Instead, they attribute the findings to a combination of lifestyle and social determinants. Factors such as chronic stress, smoking, and reproductive history are known to correlate with marital status. The study also suggests that individuals who are already healthier might be more inclined to marry.

Notable differences were observed in human papillomavirus (HPV)-associated cancers. Never-married men were five times more likely to develop anal cancer, and never-married women were nearly three times as likely to develop cervical cancer. This indicates that social circumstances may play a crucial role in cancer risk at a population level, advocating for tailored screening and prevention efforts.
