Suggest Treatment For Scars Visible On Chest X Ray

Last yr during our annual physical exam in our company my x-ray result has something they find scars on my lungs then i undergo check up to our company doc and he advice me to take medicine so i follow it for 6 months... for how many yrs existing here on earth i haven t feel any symptoms of having tb i dont smoke, and now i am scared although i already done the treatment but still afraid that the scars still appear on my xray coz i applied for abroad... is there any alternative medication that i can do? not to appear the scars on my xray if possible.
