Nodules in Lungs

Hi All - just looking for some advice and support, I hve been clear from BC for 8 months now but 3 months ago started with a bad cough and being breathless when I do anything but sit down.  X rays have shown I have nodules on my lungs and they are sending me for a CT scan this sunday so I am really worried its the C again, could it be caused by damage from the radiation? any help please xxx

Hi I have damage to lungs from radiation , was thinking all sorts of things .I have fibrosis of top right lung , cancer was in right breast.
