Angry Besides hyperthyroidism, is there something else going on?

I am a 27 year old female and last month I decided to go get a physical done because I want to loose a significant amount of weight and wanted to monitor my health along with the weight loss. I had one set of blood work done, then an ultrasound, then more blood work and then a nuclear thyroid scan. After the first set of blood work results came in I was diagnosed with hyperthyroidism. My results are as follow (includes both sets of blood work concerning thyroid only):
T4 FREE (DIRECT): 1.46
Thyroxine (T4): 9.9
T3 Uptake: 33
Free Thyroxine Index: 3.3
Thyroid Peroxidase (TPO) Ab: 353
Rheumatoid Factor: 234 (I was diagnosed with Rheumatoid Arthritis at 17 and told that when you have one autoimmune disease it is probable others show up)

After the blood work I was scheduled for an ultrasound, the results follow:
Right thyroid lobe = 50x48x15mm
Left thyroid lobe = 50x20x11mm
Thyroid isthmus AP diameter = 2.8mm
Generalized nonhomogeneous thyroid tissue echogenicity
No cyst or delineated abnormal solid mass identified
Unremarkable surrounding visualized muscles and vascular bundles
No focal abnormality is identified and a nuclear thyroid scan is recommended for further evaluation.

Results of the nuclear thyroid scan:
TSH 0.01 Radio-pharmaceutical 285 mCl of I-123 p.o.
Scan demonstrates asymmetrical size of the right and left lobes of the thyroid gland. Heterogeneous scan throughout the left lobe. Cannot exclude a hot nodule. 4 hour uptake 19.2% elevated normal for value of 5-12%
24 hour uptake 36.4%, normal 24 hour uptake 13 to 30%
Abnormal 4 hour and 24 hour increased uptake. Asymmetrical activity in the right lobe of the thyroid gland.

After all these test the only thing I have heard from my doctor is that I am hyperthyroid, I have not being placed on medication and today she referred me to a specialist (endocrinologist) to "check if what I have is benign or malignant." To me it appears that I don't have any nodules or cyst, why would they need to check if I have cancer or not? Also, I don't understand why I have been taking so many test if she was able to tell from the initial blood work that I have a hyper thyroid? I feel a little confused, especially after so much blood work and test and so little feed back. Any help is greatly appreciated. I just want to know if there is something serious to worry about.

Re: Besides hyperthyroidism, is there something else going on?

I'm certainly no expert on nodules or hyperT. But it does appear they're evaluating whether you have a hot nodule causing yours. See the part in the report that says, "Cannot exclude a hot nodule"? That would be a good thing, actually, better than if you had Graves' disease. It would be easier to treat. A hot nodule has an almost zero chance of being cancer, not to worry much about that.

Sorry I can't help much more than that. Let us know what happens at the endo's.
