Michele,
It sounds possible that doctors may adjust their plan of treatment depending on the patient's response to radiation but the patient has the right to know the reasons for such changes. Originally, I was planned to have 42 sessions of radiation but when I still had 5 or 6 left, the oncologist told me that I would need 6 more as a boost. He discussed this change of plan at his office and had to ask for my consent even though I had no option.I was given a card of schedule so that I knew exactly when I should show up and how many sessions were left. The technician would sign against the date after each session and so there wouldn't be any argument over the number of sessions left. As for the CT, I didn't have any during treatment as the tumors were still shrinking. The biggest tumor on my left neck measured more than 7 cm. I had the CT 2 months after completing the treatment. The next one was done 6 months later.You are right that you need clarification asap to ensure that your husband is receiving the right and proper treatment.
