Surprise! Surprise!  Rats bred to easily develop tumors do!  You could probably give them a series of injections and they would develop tumors from that.   I think by now, if dogs actually showed a propensity to get tumors from chips, we would be hearing about it on sites like this and in veterinary peer review journals, wouldn't we?  And if a rash of those stories start, we can have inserted chips removed.     
Good info, Nancy.  Thanks.
