Cancer treatment in stealth mode

I find this fascinating. Stealth mode makes me think of spies, CIA, cold war, KGB, NSA, guerrilla warfare, covert operation and all that.I found an article on Smithsonian.com, The War on Cancer Goes Stealth, which explains in detail what exactly they are doing - tricking cells, sneaking past the sentries, etc. I know it needs more testing and many researchers will be busy with this for a long time but treatments targeting individual cancer cells so patients can avoid chemotherapy and enjoy a good quality of life.Here is a TED talk explaining it more with links to more talks on it here. This intrigues me to no end. And convinces me I should have paid more attention in biology and chemistry (physics not so much) so I could understand it better. And it shows hope for a new wave of treatment that are not as harmful to the patient.My only concerns are - how soon will this happen and how much will it cost?
