PTC recurrence?

I had a ultrasound today and it is showing this:

LYMPH NODES: Right level 3 node measures 1.6 x 0.3 x 0.9 cm. A left level 2 node measures 2.7 x 0.5 x 1.1 cm.

None of my other past scans say this. It’s also recommending an iodine scan. I haven’t had one in 10 years. This is just the radiology report and all my drs are out of office until Monday. Any insight would be great. I’m trying not to worry about what this means.
