Marriage lowers cancer risk, a US study finds

Never married individuals face significantly higher cancer risks, according to a new study. Married or previously married people have a lower risk of developing cancer, suggesting marital status is a key social determinant of cancer risk. The study found unmarried men had a 68% higher cancer incidence, and unmarried women an 85% higher incidence. The research analyzed data from over 100 million people in the U.S. and highlights the importance of social factors in cancer risk assessment.
