I'm less certain, many if not most lung cancers seems to follow chronic inflammation in the lungs.

The classic example is asbestos related mesothelioma. "Frustrated phagocytosis" is the name for the way macrophages become locked in a never ending spiral of eat, die poison loops around the asbestos.

Do we really want macrophages to go into high gear? Will we make sure no one who has it has been exposed every to any asbestos?

What about other triggers of frustrated phagocytosis? People who commute by subway (tiny metal particles).

The point isn't to say that this is a bad idea necessarily but that I'm not sure this sounds so much safer than regular vaccination.
