Thanks for posting,
From your description it is very possible that the nodule described could to be cancerous. But other possibilities may exist such as benign nodules or mass. The scan could determine exactly the nature of the nodules i.e if they contain cancerous cells or benign cells. The most sure way of finding out is doing a biopsy
. That has higher sensitivity and higher sensitivity.
Well I wish you courage and just wait for the results of the scan to come up. Worrying now will not help you much.
Thanks and hope this helps
