"mumbled something about it costing as much as the radiation". It's true the cost is really high. Its interesting that your RO thought that with IMRT it wasn't needed though. Maybe it depends on where the cancer is and so where they are focusing the most beams of IMRT, but my RO told me that even with IMRT, my left parotid and a piece of my right would still be damaged so that the amifostine still can help save salivary function there.
