Heterogeneous uptake in thyroid scan

I had the left thyroid glan removed in 1971 because of a large tumor on the gland.  A recent sonogram showed nodules in the right gland.  I had a thyroid nuclear scan and uptake on the thyroid done this week with the following results:  "Uptake values slightly low at 4 hrs but within normal limits at 24 hrs.  There is what appears to be an enlarged right lobe with slightly heterogeneous uptake but no focal hot or cold nodule present.  Findings could be due to a large hyperfunctioning goiter or nodule in the right lobe of the thyroid, although the uptake values are not significantly increased."
The findings seem to be contradicting regarding the nodules.  Do I need to be concerned about the nodules?  I am especially concerned about cancer because of my prior history.  I do feel pressure on the throat and have trouble swallowing at times.  
Thank you.

sounds like nodular goiter involving the right lobe - would do ultrasound to see if any nodule requires FNA biopsy.  The TSH blood test is much better at detecting over-active thyroid than I-123 uptake values.
