When thinking about cell signalling and sensing, I wonder if a group of cells generate ROS to "nuke" a faulty cell, I say nuke because ROS will destroy surrounding healthy cells.

The problem with this theory, is its hard to see it working in anything other than a test tube!

Lets face its not like we can audit each and every cell, its contents and condition in a body is it!?!

Sure we can use some magnetic spin with some chemicals, or radioactice isotopes with others, but the sensing equipment is what holds us back with in vivo studies, so then its back to the patient provided metadata to form an opinion.
