Marching on toward future therapies in Cancer Medicine

Most cancers result from a disturbance of our genes.  The disturbance could be functional or simply a change in the nature of genes called Mutations.  Mutations that are deleterious are those that stop or otherwise alter the fundamental function of the gene.  Genes can initiate, regulate, facilitate or simply hook to other genes.  Hooking (Adapter) to other genes has a strong impact because it can change the direction of the pathways, or give a gene the powers of the gene it is now hooked onto!  There are those who simply allow hooking to membranes as in Anchor genes that sometimes allow trans-membrane transport, sometime just providing a substrate from other reactions to occur. 
Hooks can also connect several molecules (Homeobox).

Suffice is to say that if a gene is broken, let's introduce a new gene.

The challenge is: how do we get a new gene in there?
Here we are looking at Nanotechnology to achieve this challenge!
