Teflon is harmless if ingested. The whole point of it is that it is chemically inert.
Anything bigger than a "small molecule" doesn't make it through the membranes into your bloodstream. Even individual proteins are too big, let alone a chunk of your frying pan big enough to see.
Either way, what you claim is simply not true by any reasoning [1], though I do agree eating teflon flakes in moderate amounts should not pose much concern.

Saying "Its physical properties are incompatible with human biology." is not an actual answer. What physical properties?
Fibers so small they tangle up with your chromosomes are the physical properties that can cause cancer
Look at peer reviewed papers.
Peer reviewed papers aren't absolute truth either and one usually needs to be an expert in the field to see which papers are sound and which are not, if even possible. I'd even wager there's a lower percentage of bullshit to be found on Wikipedia than in peer reviewed papers.
Crocidolite does contain iron (Na2FeIII2FeII3Si8O22(OH)2 per [1]) but it’s not the common type of asbestos and is known as blue asbestos and is found primarily in South Africa, Australia, and Bolivia.
I think given how dangerous asbestos is, it can’t statistically be reasonable to assume that it’s cancerous properties arise from something only found in a minority of the asbestos we use.
