Hey,
fetteredwolf, have you heard about
this cancer-treatment technology? It's approved and is being used, but also still being tested and the technique refined. What they say is a holdup is the difference of electrical conductivity of different body tissues, and that has me thinking that there might be a chemical substance that would regulate or just raise the conductivity of the tissue. I don't know enough about chemistry yet, and I know even less about cancer tissue, but it is really interesting to think about.
