In brief: Goiter

Goiter is enlargement of the thyroid due to inflammation usually.
Nodules or growths within a thyroid gland can be inflammatory but over time turn cancerous. Close monitoring with ultrasound is strongly recommended.

In brief: It can - but low

Although it is assumed that multinodular goiter is unlikely to contain cancer, a few study has suggested that the risk of cancer was similar in a patient with a single or multiple nodules, but the risk of malignancy was higher in a solitary nodule than in a non-solitary nodule.
Thus, a dominant nodule in a multinodular goiter should be evaluated as if it were a single nodule.- the risk is about 5%.

In brief: Not usually

Usually a thyroid goiter (enlargement) does not convert to malignancy or cancer.
If there is a nodule found by ultrasound imaging or by physical exam, depending on the characteristics it should be evaluated. There is no 100% way of knowing what will turn in to cancer.
