Does this body clock cause cancer?

I know I’ve been reading too much speculative fiction lately, when articles like this both intrigue me and scare the living crap out of me.

We used to think that white hair, wrinkles and muscle weakness were the key signs of ageing. By the turn of the century, scientists had focused their attention to changes in our DNA, such as the genes that underpin common ailments such as cancer, diabetes, and heart disease.

But in the last few years, there’s been a huge surge in interest in the way that genes are used in the body, in a field called epigenetics.

This epigenetic revolution has shifted the emphasis away from changes in genes towards changes in the ways that genes are put to work in the body. Think of it this way: the genes (each corresponding to a different protein) you inherit from your mother and father are all the possible “notes” that can be played by the instruments (cells) of the body. Epigenetics concerns how each type of cell plays a different repertoire of notes, depending on whether it is an eye, muscle or brain cell.
