No, I don't know how the nanoparticles tag and kill cancer cells, but I've heard of other processes that tried to concentrate some material in cancer cells which could be then be "microwaved" to overheat the tumor cells.
When I go to MD Anderson they use ultrasound, with digital enhancement of red & blue blood flow to see if any lesions have unusually high blood flow.
My point was that cancer cells have several differentiating features about themselves. And the inventor of this process, who has Leukemia (something that I had 10 years ago also) may not be inventing the magic bullet for his form of cancer, but he's doing incredible work for millions of sufferers and their families.
Most cancers have to steal extra bloodflow to support themselves and grow. When I had radiation a few years ago, it basically killed most of the capillaries around the tumor site and eliminated new cell growth for 2-3 years. It was a bummer for me. Radiation also caused a burn the size of a silver dollar that wouldn't heal and eventually required a major skin graph.
See my posts #48 and 51...This might be for real!
