High levels of particulate air pollution associated with increased breast cancer incidence

NIH Researchers Find Association Between Air Pollution and Breast Cancer Incidence

Summary

Researchers at the National Institutes of Health (NIH) have discovered a link between high levels of particulate air pollution and an increased incidence of breast cancer. This study, published in the Journal of the National Cancer Institute, is one of the largest to investigate the relationship between outdoor air pollution, specifically fine particulate matter, and breast cancer incidence. The research was conducted by scientists at the National Institute of Environmental Health Sciences (NIEHS) and the National Cancer Institute (NCI), both part of NIH.

Introduction

The study analyzed data from the NIH-AARP Diet and Health Study, which enrolled over 500,000 men and women between 1995-96 in six states and two metropolitan areas. The researchers focused on women who had higher levels of particulate matter (PM2.5) near their homes prior to enrolling in the study. PM2.5 is a mixture of solid particles and liquid droplets found in the air, originating from various sources such as motor vehicle exhaust, combustion processes, wood smoke, and industrial emissions. The Environmental Protection Agency provides air quality information, including PM2.5 levels, through their website known as Air Now.

Findings

The study revealed an 8% increase in breast cancer incidence among women living in areas with higher PM2.5 exposure. This finding is significant considering that air pollution is a widespread exposure that affects nearly everyone. The researchers estimated historical PM2.5 concentrations for each participant’s residence, focusing on exposures 10-15 years prior to study enrollment. They found that PM2.5 was associated with a higher incidence of estrogen receptor-positive (ER+) breast cancer, which is the most common type of breast cancer diagnosed in the United States.

Implications and Recommendations

The study highlights the importance of considering historic air pollution levels when assessing breast cancer risk. Future research should explore regional differences in air pollution and the impact of different types of PM2.5 on a woman’s risk of developing breast cancer. These findings contribute to the growing body of literature suggesting a relationship between air pollution and breast cancer.

Sustainable Development Goals (SDGs)

1. SDG 3: Good Health and Well-being – This study provides valuable insights into the impact of air pollution on breast cancer incidence, contributing to efforts to improve global health and well-being.
2. SDG 11: Sustainable Cities and Communities – By identifying the association between air pollution and breast cancer, this research emphasizes the need for sustainable urban planning and policies to reduce pollution levels.
3. SDG 13: Climate Action – Addressing air pollution is crucial for mitigating climate change and achieving sustainable development.

Conclusion

This study conducted by NIH researchers demonstrates a link between high levels of particulate air pollution and an increased incidence of breast cancer. The findings underscore the need for continued efforts to reduce air pollution and protect public health. By aligning with the SDGs, policymakers and stakeholders can work towards creating healthier and more sustainable communities.
