It's not that great if it detects whether there is cancer or not only AFTER you've destroyed the flesh with the knife.

Anyway, it is certainly an improvement, but how many millions of waiting people are going to suffer and die in the 3 years it takes the government to ensure it doesn't kill anyone.

Its great if it detects whether there is cancer or not after you've destroyed the flash with a knife, because this blood vessel rich area will need to be cauterized anyway (tumors are very good at promoting blood supply).

If cancer is detected on one pass, just do another pass. That's the way surgery in critical areas (where least tissue loss is important) is done anyway.

(a little knowledge can really turn you around, huh?)

We're moving into star trek-like medical technology! Ok, so maybe a tricorder didn't have to burn your ass to see if it contained cancerous cells, but we're getting there!

Maybe one day we'll have technology that mimics certain dog breeds' ability to smell cancer- without any incision/burn! We live in such an incredible time. I need to stop being so jaded.
