Narrator: This is Science Today. By stepping back and looking at disease through the chain of causation and how chemicals may impact various stages, researchers are hoping to determine better ways to reduce exposure to harmful chemicals. Research scientist Megan Schwarzman of the University of California, Berkeley's School of Public Health, is part of an expert panel looking into how chemicals might influence breast cancer risk.
Schwarzman: So, the purpose wasn't just to develop a boutique suite of tests to look for breast cancer or the ability of a chemical to contribute to breast cancer risk. The purpose was to pilot this approach and it looks very promising. We could find out what chemical tests are important that are unique to a disease and what are actually very common, that if we did this test on all chemicals it would be really important to know. So, where's the overlap and where is the important distinctions?
Narrator: Schwarzman adds that this comprehensive approach to chemical testing doesn't have to be limited to breast cancer. For Science Today, I'm Larissa Branin.
