[|Human|] Hi,4 years back incidently doctors found one pulmonary nodule on my right lung on chest X-rays. They asked for CT and the result shown 1.5 cm size. I undergo Bronchoscopy also, but didnt show any problem then. But after these long years I am having on and off fever. Agin asked for Contrast CT. and the result shows that the nodule grew to size of 2.6 cm. and am asked for bronchoscopy again. The first result of bronchoscopy showed on reading like 18HU. is there any possibilty of malignancy. Or is there any risk with that nodule.
[|AI|]  This is likely a growth of some sort, whether it is benign or malignant (cancer) can only be definitively determined on a biopsy. The fact that it has not grown much over 4 years makes it more likely to be benign, and would only require follow-up imaging. When there is enough concern for malignant tumors (for example if there is fast growth, or you have an extensive smoking history), the nodule would need to be surgically resected. If you are having other symptoms such as fevers and chills, then your doctor can evaluate you for an infectious granuloma being the cause of this nodule. TB (tuberculosis) or fungal infections of the lungs can do this. I hope this gives you some of the answers you were looking for.
