As a child I used to think cancer was the result of some kind of constant irritant. Later I learned that ionizing radiation is a sure fire cause. Now I've come to learn that not only is cancer a result of some viral attacks but our own genes have the ability to turn cancer on and off. It is a natural resppnse so to speak.

A normal cell has encoded within it the ability to reprodice itself a set number of times. It is a curiously descrete number of times it can reproduce itself and then it comes to what I call an end cap on the gene that says "stop here"

The end cap is a key to either "immortality" or cancer. This line of research is profound and close to practical applications.
While old school models of disaes persist the new paradigm of gene therapies are now coming within reach.
