The new study said that microplastics have been found in kidney, urinary tract, and bladder cancers. The study also found the presence of even smaller particles called nanoplastics.

Researchers found that the plastics had harmed the cells, causing both inflammation and toxicity, which were bad for the cell's survival. They also disrupted signaling between the cells, specifically on a pathway that has to do with cell growth and spreading. Both of these may be tied to cancer.
