Thank you for sharing your story. It makes no sense to me that you would have had your radiation moved because “the doc didn’t feel comfortable rushing it”. Yet you have been left waiting for 20 weeks. If you have a new date in a week’s time I would suggest going through the process. You are unlikely to be able to get treatment elsewhere any sooner. However, if there are further delays, find another clinic that can treat you right away. Keep fingers crossed that this was just a hiccup in the process. All the best!
