    Global plastic production exceeds 400 million tons annually, with over 4200 chemicals identified as concerning due to toxicity and environmental persistence.

  • 2

    Bisphenol A (BPA) is a widely studied plastic chemical linked to breast cancer risk through its interaction with estrogen receptor α (ERα).

  • 3

    The study screened nine plastic-related chemicals for estrogenic effects using high throughput transcriptomics in MCF-7 breast cancer cells.

  • 4

    Transcriptomic responses were measured to derive transcriptomic points of departure (tPODs) for assessing the toxicological potency of these chemicals.

  • 5

    Findings suggest that many BPA-like chemicals activate ERα and may pose similar risks to breast cancer as BPA, highlighting the need for further research.
