Hello doctor first of all I want to thank all the doctors over here because they always helped me in my difficult situation with their valuable answers. i have numerous times posted regarding my husband's health. My husband had suffered mediastinal lymph node tb. After 9 moths he stopped his medicine this February. But this incident impacted my mind so deeply, may be because when he suffered  we were out of India so i was feeling helpless.After ct guided biopsy and ct scan it was determined tb and after 7 months another CT was done and doctor said nodes are very  less like previous 7cm node was now 1.5 cm. So now the problem is- "my husband has some occasional cough issue, like every day he cough occasionally, but this decease impacted me so deeply that every day i woke up with fear that he is suffering from serious health issues like cancer every moment i am leaving with fear. With his occasional cough i felt like may be he has cancer or not. I have been like this for 6 months.pls hlp
