Summary

The DREAM study is an observational research project that enrolled over 1,500 pregnant women and their children to understand how exposure to environmental chemicals—like those in consumer products, air, and water—might influence cancer risk. Researchers collected blood, urine, and other samples to measure chemical levels and immune changes. The study was terminated early, so findings may be limited.
