In recent news, there have been two great discoveries – similar in theory, but very different in appearance and use – for delivering drugs. Both use remote control mechanisms, the first invention describes how a remote control pill can release its contents once it reaches the area at which the drugs need to be delivered (see:Remote-control Nanoparticles Deliver Drugs Directly Into Tumors). The second discovery takes place at the nano-level – here, Remote-control Nanoparticles Deliver Drugs Directly Into Tumors; the drugs are released by an electromagnetic field once the nanoparticles get in the vicinity of the tumorigenic cells. This therapy works well for attacking primary tumor sites; however, this therapy won’t be very robust when trying to eliminate metastatic colonies, or rogue cells that may have broken off from originating tumors. I am still bullish on an approach to cancer therapy that includes the programming of one’s own immune system to identify tumorigenic cells and destroy them.
