[|AI|]  Thanks for your question on Chat Doctor. I can understand your husbands situation and problem. Shadow on chest x-ray with chest pain in smoker patient can be due to infection (pneumonia, tuberculosis), Pulmonary embolism and infarction, lung cancer etc. So better to get done CT thorax with Contrast and bronchoscopy with BAD (bronchoalveolar lavage) analysis for diagnosis of this shadow. Smoking cessation should be the priority, so ask him to quit smoking as soon as possible. Hope I have solved your query. Wishing good health to your husband. Thanks.
