A new study found microplastics in 90% of prostate cancer tumors studied.[1] Tumor tissue contained approximately 2.5 times more plastic particles than healthy tissue near the tumor.[1] Among the types of microplastics identified were polyamide (nylon), polyethylene terephthalate (PET), and polyvinyl chloride (PVC).[1] This is the first Western study to directly measure plastic particles in prostate tumors.[1] Researchers suggest that exposure to microplastics could play a role in the development of prostate cancer, although microplastics themselves are not directly carcinogenic.[1] Microplastics can act as carriers of bacteria and chemicals that damage DNA and increase the risk of developing tumors.[1] More research is needed to confirm the link between microplastics and prostate cancer.[1]
