Radation on Cells - 02-02-2012 08:16 PM
I have a couple of questions on how radiation works and have asked a few RO and have gotten different answers. Not being a RO or meidcal person myself it�s hard for me to fully grasp how radiation works at a laymen level .
As I understand the process, radiation damages the cell�s DNA it comes in contact with and �normal� cells can repair their DNA and continue to live. Whereas cancerous cells don�t have the ability to repair their DNA and die off. If true, what happens to cells that are precancerous? Do they have the ability to repair and continue their current state, or do they go back being �normal� or die off. I assume it probably depends on how far they have changed towards being cancer. Then again,I might be totally off
