The operative word in Gary's post is "can" as in physically possible. Not necessarily probable and certainly not foreordained. On the carotid threads, I have posted that despite having 95 GY of radiation to the same tumor spot, my cartoid tests show zero RIF issues, zero plaque issues and full normal flow and systolic velocities for both right and left carotid arteries. And that is for IMRT in 2007 and Cyberknife in 2009.
We all can agree that radiation is the gift that keeps on giving. I'm glad that it has not been so generous to me as to some others here at OCF
