In brief: Only occassionally
While almost all thyroid cancers are cold, so are most benign nodules.
If the nodule is hot, it is extremely rare for it to be cancer. If it is cold and looks suspicious on an ultrasound performed or at least interpreted by a very experienced clinician, it should be biopsied to see if surgery is necessary.

In brief: Not necessarily
Cold thyroid nodules can be cancerous but are usually benign.
The next step is usually a biopsy, which is much mor helpful than a thyroid scan to distinguish thyroid cancer from benign nodules.

In brief: Cold nodules
Only 15% of cold nodules are malignant (cancerous).
It is an old technology which is not specific. Nodules should be evaluated by ultrasound and needle biopsy. I rarely find it necessary to order this test.
