Clare, it's good that you can have a positive attitude about the treatment side effects.  You might talk to your doctors about whether there are clinical trials and/or specialists who deal with this problem.  I didn't have fibrosis, but I have learned from my own experience that the oncologists are focused on saving your life and sometimes don't have as much knowledge about treating side effects as other doctors.  Often it can take a year to recover from cancer treatments, so I'm not surprised that you are still recovering seven months later, but if you can find a doctor who knows more about radiation fibrosis, there might be something more that can be done for you.
