this deserves a bump, because I find it really interesting, and I'm curious what everyone else thinks of it.

So the person who had this implant refuses to get it tested for fear that it will disappear and no results will be found. Quite a valid concern, but a risk I would deem acceptible. Photographic documentation exists of this object. No matter what, this person has proof that a strange object was found inside his/her body. At least so long as they retain image documentation. Without further study, no other information can be gleaned and it will stay an object of curiosity.

Nice to see, but as it is, I'm skeptical of anybody who would refuse analysis of foreign objects in their bodies that has the ability to document its existence up until the time of a testing procedure.

I would further go on to think that if I did suspect an alien implant, I would want it removed and taken away from place of residence. If alien implants are real, then they most certainly would be used to track the individual and potentially subject them to further unsettling surgical procedures against their will. I would want the object as far away from me as possible.
