My wife is in Thailand and when undertaking a medical a 2 to 3 cm shadow was detected on her lung. At first they thought it was TB but so far tests have shown nothing. She had a blood test 3 months ago which was also negative. What other diagnosis apart from cancer could it be. She does not drink or smoke.
Thanks for your question on Chat Doctor. I can understand your concern. Apart from tb and cancer following diseases' cancer cause 2-3 CA shadowing the lungs. 1. Benign cyst 2. Benign nodule 3. Old scarred lesion from previous lung infection or lung injury. 4. Localized bronchiectasis. So better to consult pulmonologist and get done clinical examination of respiratory system, CT scan of thorax and bronchoscopy with BAD (bronchoalveolar lavage) analysis for the diagnosis of this shadow. Hope I have solved your query. I will be happy to help you further. Wishing good health to your wife. Thanks.
