ATMOSPHERIC FINE PARTICULATE MATTER POLLUTION around homes and workplaces increases breast cancer risk. We have a new breast cancer risk factor, according to research presented at the European Society of Medical Oncology (ESMO) 2023 Congress.

I am involved in the management of many women (and the occasional man) with breast cancer.

This study is the first to examine the association between atmospheric pollution (at home and in the workplace) and breast cancer risk.

Today, I want to examine the XENAIR study. I will then remind you of some lifestyle tools to reduce your breast cancer risk.

A New Study — A New Breast Cancer Risk Factor

The XENAIR study carried out on the prospective, longitudinal E3N cohort a year ago showed an increased risk for breast cancer after exposure to five atmospheric pollutants.

The project involved collaborating with several specialist teams from France and the United Kingdom.
