Breathlessness a year after radiotherapy - anyone else?????

Hi - I have recently suffered from breathlessness & as bad cough & went to docs - had a chest X ray last tues & it has come back with inflamation of bronchila tumes but they have advised I now need a CT scan tosee what’s going on. I have read about possible rare breathlessness caused by slight damage to lungs from radiotherapy - Has anyone else expereinced anything like this. I paniced initially thinking it might be secondaries but am now calmer & inclined towards this as a possibility - I will obviousky know more once scans done but in the meantime thought I’d ask if anyine else had any experiences to share.
