Genes do not cause neither disease nor cancer.
They indicate a predisposition to disease.
Gene mutation is a creative response to a perturbation. Not an error.
Living entities are controlled by two conservation laws:
1. Conservation of the individual
A living system responds to an external
perturbation by restructuring its processes so as to
improve its survival
2. Conservation of the community
