“Thanks for the comments and don't worry-here is why.
First: we are nowhere near the level of sensitivity of seeing cancer at the level of one or
several errant cells.
Second: in a time very far from now (and perhaps in a different Universe) phyicians will
perform surgery just on the basis of a sensor response. In our time and space, visual
inspection of the site and biopsies will be with us for a looooong time.
Third: we can all do preventive medicine without seeing Dr. Gallagher, me or any of our
physician colleagues, as there are ample places for advice on keeping skin healthy; if you are
genetically prone to skin disease then frequent physical exams are already recommended.”

I remember reading somewhere that our bodies are constantly producing errant cells that could become cancer, but that most of the time our immune system shuts them down before they do any harm. What if Michelle Gallagher’s new process detects cells that NEVER would have become cancerous and we end up performing needless procedures and possibly scarring otherwise heathly people?

Is it possible to take preventative medicine too far?
