Thanks for your question on Chat Doctor. I can understand your concern. Calcification in lungs on chest x-ray is always suggestive of old, healed scarred lesions. You might be having previous tuberculosis or pneumonia or any lung injury which heals by calcification. This might interfere with your medical clearance. So better to consult pulmonologist and get done CT thorax and bronchoscopy with BAD (bronchoalveolar lavage) analysis. If both of them are negative then no need to worry about active infectious disease, and you will clear your medical fitness. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
