My husband has mediastinal lymph node tb. After 9 months of medicine in 31st January 2023 we did CECT it was normal much decrease in size report is attached. He is going daily office day to day work. One thing is he sometimes cough occasionally. My question is is there any need to do follow up examination of his chest ? If yes doctor, then how often should we do it? As it was done 3months ago. Is tb make his lungs weak ? Is this make any probability of cancer in late future? As he occasionally cough, nd it is happening since the beginning previously it was too much now occasional,I remain bit worried everytime. he is a non smoker and non alcoholic. He doesn't smoke a single time.
