Clearly you are confused Donald. Not all life is subject to degeneration of the cells. Biological Immortality is a thing. It means that a living being is immune to senesence, and therefore cannot die by aging. A number of species are Biologically Immortal, and I would not be surpised if the Imperium found a way of introducing immunity to senesence in the form of Astrate Modification.
