[|Human|] I just had a CXR in which the radiologist identified 2 possible adhesions, but also stated that they are rounded on the frontal view and therefore cannnot rule out neoplasm.  They want a comparison CXR but I dont have one.  Any advice? How do you differentiate the 2??
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Honestly speaking, one can not diagnose neoplasm (cancer) or adhesion only on the basis of chest x-ray. Chest x-ray is giving only Two dimensional (2D) picture of any lesion. It is only screening test for lung lesion. For confirmation, you need CT scan. CT will give you three dimensional (3D) picture. CT will also tell you about exact size, shape and margins of lesion, association with surrounding lung, necrotic center or not, mediastinal lymph node enlarged or not etc. All these things are important in differentiating between neoplasm (cancer) and adhesion (benign lesion). So better to consult pulmonologist and get done CT scan and discuss all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
