[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. To have lung scars after treatment of tuberculosis is normal healing phenomenon. These scars are inactive, harmless, noninfectious lesions. So no treatment is required for this and no treatment is available today remove them. But for visa clearance, we need to prove that these lesions are not active and infectious. For this, you need to get done CT thorax and bronchoscopy with BAD (bronchoalveolar lavage) analysis. CT is more superior in diagnosis of scar lesion as compare to chest x-ray. If both these are negative for active infection, you can argue with visa authority that these lesions are old, healed, scarred lesions and not active, infectious lesions. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
