Groundbreaking Study on Chemical Mixtures & Breast Cancer Risk

This is an excerpt of a longer post on the Zero Breast Cancer site describing an upcoming UCSF study on chemical mixtures.

Chemicals linked to breast cancer risk come from many sources: our personal care products, cleaning supplies, food packaging, pesticides, the air we breathe, the water we drink, and more. These chemicals, including endocrine disrupting chemicals and mammary gland carcinogens, can alter vital pathways in our bodies. While most research has focused on single chemicals, in reality, we are not exposed to chemicals one at a time. We are exposed to many chemicals at the same time throughout our daily lives.  . . .

Understanding the impacts of BPA substitutes on male fertility

Bisphenol S (BPS) was once promoted as a safer substitute for bisphenol A (BPA), a chemical widely criticized for its potential health risks. As concerns over BPA grew, manufacturers started replacing it with chemicals such as BPS in food packaging and receipts.  . . .

Health Impacts of PFAS Exposure During Pregnancy

PFAS, also known as per- and polyfluoroalkyl substances, are often called "forever chemicals" because they don’t break down easily and can remain in the environment and our bodies for a long time. Over the past decade, the harmful effects of PFAS on human health have become increasingly clear with pregnant women and children especially at risk.

Climate Anxiety 102: Navigating crises & resilience

Extreme weather events are becoming all too common, and the human consequences of climate change are now very evident — from job loss, displacement, and destruction of landscape and personal property to disconnection from social networks, communities, and resources.  . . .

A Roadmap to Better Policy for Plastic Chemicals

The petrochemical industry produced 460 million tons of plastics in 2019. This number is expected to triple by 2060. A wide range of chemicals – such as bisphenols, phthalates, and flame retardants – are routinely added to plastics. Many of these plastic chemicals are known to be harmful, and they do not stay in the plastic material. They can be released during feedstock extraction as well as the production, use, and end-of-life of plastics.  . . .

Safeguarding Science: Protecting researchers & scientific integrity

Independent environmental health researchers work within an economic system that is often hostile to their findings. When their research reveals environmental or health hazards, it can lead to regulatory actions and the possibility of financial losses for industries. In some cases, these industries may attempt to discredit and silence scientists through tactics like funding counter-studies, launching PR campaigns, or engaging in legal battles.  . . .

Cancer in Young Adults: The role of the food system

According to the American Cancer Society, about 80,000 adults aged 20-39 are now diagnosed with cancer every year, with the most common types being breast cancer, lymphomas, thyroid cancer, colorectal cancer, and brain and spinal cord tumors. This number has been on the rise in recent years, sparking public health concerns and raising questions about the drivers of the upward trend. The potential contribution of the food system – from food packaging and agricultural chemicals to diet and nutrition – is a key area that cannot be ignored.   . . .

Attacks on Scientists: Lessons from the Monsanto papers

In the documentary film Merchants of Doubt, Marc Morano, a former staffer for Senator James Inhofe (R-OK), described working to thwart action on climate by attacking the scientists speaking out about the crisis. “You’ve got to name names and you’ve got to go after individuals,” Moreno said. He describes how they “went after” climate scientists James Hansen and Michael Oppenheimer – “and we had a lot of fun with it,” he adds.  . . .

Plastics: Multiple problems in urgent need of solutions

Oceanic currents deposit enormous amounts of debris into an expansive area of the Northern Pacific Ocean sometimes called the Great Pacific Garbage Patch. Sailing through that gyre in 1975 was like wandering through a poorly-curated community yard sale with few treasures and lots of trash — mostly plastic. Thick then, it is worse now.  . . .
