Preventing Cancer Through DNA Replacement?

On the Cancer Complexity forum, I pose a question: if we could somehow replace all the damaged DNA in each of the cells of your body with an undamaged copy on a continuous basis, would that prevent you from getting cancer?

What do you think?

    I paraphrase Kurzweil by describing a supervisor (nanobot) walking through a Toyota factory (the human body) 24/7 examining each individual robot (cell) on the assembly line.

    If the supervisor finds a robot has somehow started making huevos rancheros instead of spot welding a CV joint, the robot is immediately replaced with a functioning spare and broken down for spare parts.

    How would that address the to-be-mutated cells that will be occurring in the future?

    Hi JK –

    Rafe proposes that this is done on a “continuous basis” so presumably the cells would be replaced before they could do any harm. Today, tomorrow, and in the future.

  • I asked this question of Aubrey de Grey, who is the foremost leader on halting aging, and here’s what he had to say:

    “If we discount the possibility that the cancer cell could somehow exclude or disable the nanobot, then no, I can’t see how this would not prevent cancer.”
