Thank you for your question Ananda. Firstly I would say it is not a normal thing to have a tumour in the lungs as the lungs are the site of exchange of gases between the environment and the body. Secondly a tumour in the lung at her age could probably be benign meaning it is not cancerous or malignant meaning it is a cancer and has chances of sreading to other parts of the body. The fact that she is in good health now, it does not exclude that the tumour could be dangerous to her health in the long run as the tumour could start compressing other organs in her chest. I would advice you visit your consulting physician so that other necessary test are carried out to confirm the exact nature of the tumour so that an appropriate treatment is undertaken as waiting allowing time to pass might cause the tumour to increase in size to an extent where little or nothing could be done. Better still I would advice you seek the opinion of another specialist a thorcaic surgeon or a pneumologist. Goodluck and my regards to your niece.
