Is cancer treatment possible through nanotechnology? How?

Nanotechnology is already being used to help cure cancer, just not quite in the way your probably thinking. It is possible that one day we will be able to engineer nano robots that can go into the human body detect and destroy cancer cells by themselves but for now they use nanotechnology in their other tools to refine their ability to map out and treat cancerous regions. Nanotechnology allows accurate readings to made of tissue. Then nanoparticles then can be used to specifically target cancer cells minimizing damage to other tissue.
