but there have been eye-opening studies if you have been paying attention.

You picked the wrong guy for this. Junk science in a second rate journal is not eye opening. Correlation is not causation.

"Compared to adjacent non-cancerous tissues, tumor tissues exhibited a greater variety and distribution of microplastics. "

Because cancerous tissue does not have the intact structure of normal tissues. They see all kinds of stuff in tumors that the lymphatic system clears out of healthy tissues. That paper does not show HOW plastic polymers could cause tumors, because no one can show this in 50 years of research.

Again, we have been implanting plastic stents and meshes and prosthetics for 60+ years. The experiment has been done.

Since this thread is looking for something to be afraid of, look at coffee brewing with and without paper filtration. Filtered brews yield caffeine and compounds healthy for liver functions. Unfiltered coffees contain diterpenes, cafestol and kahweol, which signficantly raise total and LDL cholesterol, which is bad. Actual science, not media driven hype fear.
