Thyroid nodules are lumps or small growths
in the thyroid gland, a hormone-secreting gland located in the neck. About
90 percent of thyroid nodules are benign (noncancerous).
In contrast to thyroid nodules, the term goiter is
used for enlargement of the entire thyroid gland, which usually occurs because
the gland is attempting to produce more thyroid hormone. The December 1, 2004,
issue of JAMA includes an article about thyroid nodules
and how they should be treated.
