Thanks for your question on Health Care Magic.
I can understand your concern.
Nodule on chest
x ray is mostly an incidental finding. Usually it is
benign cyst only. But we need to rule out early
lung cancer first.
So first get done CT thorax with Contrast.
CT thorax will give you much more idea about nodule size, margins, content, association with surrounding lung and mediastinal
lymphnodes.
On CT, if it is benign lesion then no need to worry much for this nodule.
But if it is suspicious of malignancy then you need
biopsy for confirmation.
So at present, no need to worry. Get done CT thorax with Contrast and discuss all these with your doctor.
Hope I have solved your query.
I will be happy to help you further.
Wish you good health. Thanks.
