Plastics, Chemicals, and Cancer: The Role of the Global Plastics Treaty in Preventing Breast Cancer
February 27, 2025 @ 11:00am (AKST)
Breast cancer rates are rising globally, especially among younger people. Although known risk factors including increased age, obesity, alcohol use, and genetics play a role, the World Health Organization estimates that about half of breast cancer cases occur in women with no identifiable risk factors. This has led researchers to turn to hazardous environmental exposures, such as chemicals in food, water, and consumer products, as likely factors.
In a recent study, researchers at the Silent Spring Institute identified more than 900 chemicals that could increase breast cancer risk and found that 414 of these chemicals are used in plastics. Many of these chemicals are commonly found in food packaging, personal care products, and household items, making exposure nearly unavoidable.
The ongoing negotiations for a UN global plastics treaty to address plastic production and waste present a critical opportunity to regulate hazardous chemicals in plastics and reduce exposure around the world.
Join us on Thursday, February 27, at 11:00 am (AKST) for a CHE-Alaska webinar featuring study co-authors Dr. Jennifer Kay and Rashmi Shakti, who will discuss their findings and how the global plastics treaty could help lower breast cancer rates worldwide.
CHE-Alaska is part of CHE’s broader network, which is an international partnership of almost 5,000 individuals and organizations in 87 countries and all 50 US states that are committed to addressing environmental impacts on human health across the lifespan.
We encourage you to become a CHE partner so you can receive their monthly email newsletters, announcements about upcoming webinars, and other updates on a range of environmental health topics. Visit www.healthandenvironment.org to learn more.
Featured speakers
Jennifer Kay, Ph.D., is a Research Scientist at Silent Spring Institute. After completing her PhD and postdoc at the Massachusetts Institute of Technology studying how DNA damaging exposures induce cancer, she now applies that background to study chemical breast cancer risk factors. With the goal of identifying and reducing exposures to the riskiest chemicals, she combines experimental approaches to understand how endocrine disrupting and DNA damaging chemicals cause breast cancer with publicly available toxicity and exposure data to identify which chemicals are most likely to cause this deadly disease in humans.
Rashmi Shakti joined Silent Spring Institute in the fall of 2023 as a Research Associate, after graduating from Harvard with a bachelor’s degree in Applied Math in Biological Sciences. They are applying their computational expertise to identify how chemicals cause breast cancer and which chemicals are most likely to underlie rising rates.
