Thanks for your question on Healthcare Magic.
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 dimentional (2D) picture of any lesion. It is only screening test for lung lesion.
For confirmation, you need
CT scan.
CT will give you three dimentional (3D) picture.
CT will also tell you about exact size, shape and margins of lesion, association with surrounding lung, necrotic center or not, mediastinal lymphnode enlarged or not etc.
All these things are important in deferentiating 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.
