Microplastics
Pilot study finds microplastics in most prostate tumor samples, with higher levels than nearby benign tissue

Researchers at NYU Langone Health reported detecting microplastics in prostate tumor tissue from a small group of men undergoing prostate removal surgery, with average concentrations about 2.5 times higher in tumor samples than in nearby noncancerous tissue. The team says the findings, scheduled for presentation Feb. 26, 2026, at the American Society of Clinical Oncology’s Genitourinary Cancers Symposium, add early evidence that microplastic exposure could be relevant to prostate cancer but do not establish cause and effect.
Recent research has cast doubt on alarming claims about microplastic ingestion, such as consuming a credit card's worth weekly. While microplastics are widespread in the environment and human tissues, studies suggest exposure levels are far lower than feared, and health impacts remain unclear. Experts urge caution until more rigorous data emerges.

A research team has outlined a fluorescence-based strategy designed to make microplastics and nanoplastics visible inside living organisms, potentially enabling real-time tracking of how the particles move, change and break down in biological systems.
