Cancer isn't caused by proteins in the way you might think. Its definitely not infectious at the protein level. You could ask if this disruption spreads out cancer cells themselves and that would be fair to ask. But then the cancer cells were already in your body and were likely trying to migrate to other sites anyway.

Ok, but this might stimulate migration further.

		The success of surgery to remove solid tumors usually hinges on whether there are "clean margins," meaning they were able to remove all the bad tissue and a little good surrounding tissue just to be sure. It's likely that the same principle applies using this new procedure: if you blast the whole thing and trust the body to clean up the mess, hopefully there won't be anything left to worry about.
