Ken,

I think, Joe was asking about an INITIATION source.

And he, obviously, did not challenge DNA's changes,
which are associated with the cancer.

It is quite possible that the cancer initiation center
is outside of DNA.

So the question is still opened.

Could be that cancer associated changes in DNA are
only the secondary to the prior - INITIAL change in
somewhere within the cell?
