Our Environment and Breast Cancer: Working for a Healthier Future
Many years of research show that toxic chemicals in the air we breathe, the food we eat, the water we drink, and the products we use are affecting our hormones. BIPOC and people with lower incomes are much more likely to live, learn and work in areas with greater exposure to these chemicals.

Join Zero Breast Cancer for the October webinar in our 25th Anniversary Advancing Health Equity in Breast Cancer series as we look at how our environment can increase our risk of breast cancer. Our panel will feature Nse Obot Witherspoon of Children's Environmental Health Network and Deysi Flores of Make the Road NY discussing what we know and what we can do to protect ourselves and future generations.

Oct 21, 2021 12:00 PM in Pacific Time (US and Canada)
