There is a company, Dangerous Things, that makes a non-FDA approved probably will give your cancer cancer magnet that's designed to be implanted under your skin. They actually have two. One is axially magnetized to help you feel magnetic fields and the other is diametrically magnetized to maximize lifting power.
