Envision zero breast cancer

Dr. Dimitri Abrahamson is a scientist at UCSF, working alongside Dr. Kimberly Badal in her ongoing chemical mixtures study. As a computational chemist using virtual laboratories, in addition to test tubes, Dr. Abrahamson’s expertise is in the connection of technology, medicine, and chemistry. Camille Sytko (Science Communications Intern) and Lianna Hartmour (Zero Breast Cancer Program and Communications Director) at the Collaborative for Health & Environment (CHE) had the opportunity to interview him to better understand the important role machine learning plays in the study, and what benefits machine learning may continue to bring to the field of environmental health.

In 2025, Zero Breast Cancer continued to thrive as part of the Collaborative for Health and Environment (CHE). Our ongoing work in multigenerational breast cancer risk reduction, survivorship, and research partnerships is moving us toward our vision of a world with zero breast cancer. Below we have spotlighted outcomes of some of our most impactful programs.

This blog is the fourth in a series about an ongoing study that examines how environmental exposures to chemical mixtures may contribute to breast cancer risk (the first blog explains the study, the second explains non-targeted analysis, and the third explains DNA methylation). The study is led by Dr. Kimberly Badal from the University of California, San Francisco. In addition to collaborating with other researchers, Dr. Badal’s study prioritizes collaboration with breast cancer research advocates. The three advocates involved in this study are breast cancer survivors whose lived experience makes them uniquely suited to communicate the need for environmental breast cancer research and ensure that the research represents patient interests.

Zero Breast Cancer’s Lianna Hartmour had the opportunity to speak with advocates Vivian Lee, Susie Brain, and Diane Heditsian about why there is a need for advocate involvement in environmental breast cancer research. She also spoke with Dr. Badal to hear her perspective on how advocates inspired her research.
