Microplastics, plastics, and their products exposures and cancer: a pooled analysis

Summary

This pooled analysis of existing case-control studies found only a weak correlation between microplastic and plastic exposure and cancer risk. The authors caution that the evidence is limited by methodological problems in the available studies. While this does not rule out a cancer connection, it highlights the need for better-designed research to understand whether long-term microplastic exposure truly increases cancer risk in humans.
