A pilot study found microplastics in human prostate tissue, raising concerns about a possible environmental risk factor for prostate cancer. Researchers detected microplastics in 90% of cancerous tumors and 70% of benign samples, with tumor tissue containing about 2.5 times more plastic than healthy tissue.
Microplastics come from the breakdown of everyday products like food packaging and cosmetics. They can enter the body through contaminated food or water, inhaled airborne particles, and possibly skin contact.
Although the study included only 10 patients, scientists believe the particles may promote cancer through chronic inflammation. Microplastics can become trapped in prostate tissue, triggering a long-term immune response that may damage cells and contribute to tumor growth.
