Son of Patient,

Like PaulB said, there are a lot of possible side effects from radiation (and chemo, for that matter). During treatment, it’s important to make sure the patient isn’t dehydrated. This can happe very fast and can make the patient feel really awful. The other is mouth sores. These need to be monitored so that there is no infection.

You should ask the doctor how much radiation your father is going to get. My husband got 70 grays (gy) initially and then 20 gy twice in a different area. What the patient gets each day depends on how many days the radiation treatment lasts — my husband initially got 2 gy per day over 35 days, then the next two times he got 4 gy per day over 5 days each treatment.
