If I was making the decision over again, and had decided on Radiation again, I would’ve taken the prostex test first, to check for radiation sensitivity. If I was sensitive, I would’ve had the discussion of whether I could space out five sessions of radiation enough to make a difference, or whether I should have more doses at lower dosage levels. I certainly would have spaceoar again to minimize my risk and I definitely would have chosen a real time Mri based SBRT Machine like the Mridian or Electa Unity, again. If Proton had a built-in Mri, I might very well have chosen it, but it still is not available.

I have not seen any studies or reports related to data collection on how changing the timeframe of your radiation treatments might impact the results or your sensitivity. It certainly is worth discussing with your doctor.
