A thyroid nodule is a growth within the thyroid gland. Thyroid nodules are extremely common, and nodules large enough to be felt can be seen in 5 to 10 percent of women and 1 to 5 percent of men. A goiter is an enlargement of the thyroid gland and may be due to general enlargement of the gland or enlargement due to the presence of multiple nodules.

A thyroid nodule is not the same thing as a goiter. Thyroid nodules are growths or lumps in the thyroid gland. A thyroid goiter is an enlargement of the thyroid gland. A goiter can be due to generalized enlargement of the thyroid gland, or the presence of multiple nodules.

A thyroid nodule and a goiter are two different things. A thyroid nodule is a small lump on the thyroid gland that may be normal or abnormal. Sometimes, a thyroid nodule can be a cancerous or precancerous lump. Goiter is when the entire thyroid gland is swollen. This is not usually associated with cancer but can be associated with different thyroid diseases.
