Even though I know for a fact that the exact same areas got a second round of radiation when my tumor came back, I often read posts on OCF about doctors telling patients you can not have radiation a second time if the cancer comes back. Some posters try and defend them saying anyone who has had a second TX of radiation must be confused about where they had the radiation in the first place or that we just didn't understand our doctors.
I had thought that because I had IMRT the first time, the only way re radiation was possible was because the second time my CCC used CyberKnife since it focused better and they could minimize the pathways that had had IMRT getting even more.

Finally, here is an OCF news article about "Reirradation" using IMRT both times. So even with regular IMRT, they can do it a second time if the cancer comes back. The total median GYs are reassuring to me: 61 and 49 for a total of 110 GYs since I had 72 GY first then 25 GY for 97.
OCF re-irradation study
Those of us who have had the cancer come back certainly don't need doctors dropping the ball on treating us because they don't know you can have Radiation a second time. OCF to the rescue with a citable study instead of personal anecdotes.
