Abstract
With growing concern over high cervical and breast cancer mortality rates, this study was designed to examine the factors influencing attendance in breast and cervical cancer screening among working women in Japan by conducting a secondary analysis using nationally representative panel data from the Japanese Household Panel Survey (JHPS) and the Keio Household Panel Survey (KHPS) between 2019 and 2022, which showed that reduced screening attendance was associated with higher conscientiousness and neuroticism (possibly because of increased anxiety or fear of adverse results), suggesting that health-promoting behaviors and personality traits do not always align with preventive health actions, such as cancer screening.
