The vast majority of the thousands of chemicals in our homes and workplaces have not been tested to determine if they cause cancer. That’s because today’s options are lacking. Rodent tests are too slow, and cell culture tests don’t replicate how cells interact in the body, so their relevance to cancer is limited. Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have set out to change that.
