Envision zero breast cancer

We’re pleased to announce that tickets are now available for our 2025 fundraising event to support Zero Breast Cancer’s work. Steps Toward Prevention: A seaside walk and research talk for Zero Breast Cancer will take place in Bolinas, CA at the Commonweal headquarters on Sunday, October 26th from 1-5pm PT.

In this third blog in our series exploring how chemical mixtures relate to breast cancer risk, we explain what DNA methylation is and how it is relevant to a groundbreaking new research study. (Read the first blog explaining the study background and the second blog explaining non-targeted analysis.)

The study is led by Dr. Kimberly Badal from the University of California, San Francisco, with help from Dr. Hannah Lui Park from University of California, Irvine and other researchers. It aims to find out which individual chemicals and chemical mixtures are linked to breast cancer. The study will give insight into how we can reduce exposure to chemicals to lower the risk of getting breast cancer. We interviewed Dr. Park about DNA methylation, the method she brings to the study.

Zero Breast Cancer (ZBC) at Collaborative for Health & Environment (CHE) offers breast cancer prevention and survivorship health and wellness programs, including a health and wellness coaching program. We also provide resources on breast cancer prevention for audiences of all ages — from five-year-old children through survivors.

For more than 28 years, ZBC has centered community perspectives in our program and resource development. To illustrate how this works, I’m going to explain the development of our bilingual Generations/Generacionesresources about the impact of endocrine disrupting chemicals (EDCs) across generations.
