Moderate PM exposure increases prostate cancer: a longitudinal nationwide cohort study (2010-2020).

INTRODUCTION

Fine dust exposure has been reported to affect patients with prostate cancer, making it crucial to understand how environmental pollutants impact health. This study aimed to determine the risk of prostate cancer in South Korea associated with moderate levels of fine dust (PM) exposure.

METHODS

We analyzed data from 20,430 individuals in the National Health Insurance Sharing Service database from 2010 to 2020, comparing a new prostate cancer group ( = 4,071, 19.9%) with a non-prostate cancer group ( = 16,359, 80.1%). Using PM data from Air Korea's annual average air quality database, we conducted logistic regression analysis to assess the risk of prostate cancer.

RESULTS

Our findings indicate that even moderate PM exposure is a risk factor for developing prostate cancer. Additionally, even at low levels of PM, moderate PM exposure significantly impacts prostate cancer development, with lifestyle ha bits potentially lowering this risk.

DISCUSSION

These results underscore the need for stricter environmental standards for PM and proactive policies to reduce public health and long-term social costs. Public awareness, including mask use and air quality management, is essential.
