Could using a face wash w/triclosan in it for many years cause nasal tumor (from accidental flushing of soap in nose etc)? would more ppl have if so?

Not likely. Note that there are questions about triclosan. It is apparently no better than any other skin cleanser from a medical point of view. It may have detrimental effects on normal skin bacteria. These soaps can be irritating. But it probably does not cause cancers.
