Bonnie, it is not the case that everyone who has rad loses their salivary glands. That used to be the case, but with the advent of IMRT, which allows the radiation to be more precisely focused, many times some of the parotid glands are spared. If it is decided that your daughter will need radiation, it will be necessary to closely question the radiation oncologist about this. If the facility where she is being treated does not have IMRT AND if she is a candidate for it, you may want to have her treated at another facility. Although I had 37 sessions and was told the parotid glands on the right side would be sacrificed, they eventually came back and I do not need to carry a water bottle. Always remembering that every patient and his/her treatment is different, I nevertheless hope this helps calm some fears.
