What is considered a large thyroid tumor?

Large thyroid nodules (>4 cm) are frequently referred for surgical removal because of concern for cancer, even if they demonstrate no structural impingement upon surrounding neck structures (14–16).

What size thyroid nodule is too large?

On the other hand, almost everyone with a thyroid nodule larger than 1.0 to 1.5 cm in diameter must be investigated for the possibility of thyroid cancer.

Are large thyroid nodules more likely cancerous?

In the evaluation of thyroid nodules for malignancy, the size of the nodule has been a cause for concern, mainly because the size—if it is a carcinoma—directly influences the staging. In addition, larger nodules in other organs, such as the adrenal gland, are more likely to be malignant.

Can a very large thyroid nodule be benign?

More than 95 percent of thyroid nodules are benign (noncancerous), but tests are needed to determine if a nodule is cancerous. Benign nodules include: Multinodular goiter, also called a nontoxic goiter. The word goiter means the thyroid gland has grown too large.

Should a 4 cm thyroid nodule be removed?

Previous studies had shown that between 11- 20% of cancerous nodules ≥ 4 cm may be misclassified as benign (false negative) and this has led to recommendations that all nodules > 4 cm should be removed.

At what size should a thyroid nodule be removed?

Can a 4 cm thyroid nodule be benign?

Introduction: Most thyroid nodules are benign. Some studies have shown largest nodule size, specially >4 cm, can predict malignancy and reduce fine needle aspiration (FNA) accuracy.

What is the average size of a cancerous thyroid nodule?

When the analysis of nodule size was compared with the type and distribution of thyroid malignancy, a significant relationship was detected. The majority of cancer cases, having a nodular size of 1.0-1.9 cm, were diagnosed as papillary carcinoma, and 61.9% of cancerous nodules ≥4 cm were follicular carcinomas.

What is an abnormally large thyroid gland?

Goiters: Abnormally Large Thyroid Glands. A goiter is an abnormally large thyroid gland. A goiter develops either because the whole gland is swollen or the gland has multiple growths or nodules on it. While some people with a goiter have no symptoms, others may have symptoms of an overactive or underactive thyroid.

What causes enlarged thyroid?

The range of medical conditions which can cause thyroid gland enlargement include: Thyroid nodules and thyroid cysts (VERY common with up to 4-10% of the entire population who has one of these) Thyroiditis caused by inflammation, infection or autoimmune disease.

What are thyroid tumors and what do they mean?

What Are Thyroid Tumors? The thyroid gland is located in the front of the neck at the base of the throat. Thyroid tumors are either benign (noncancerous) or malignant (cancerous) growths. Examples of benign tumors are adenomas, which may secrete thyroid hormone.

What are the different types of thyroid tumors?

Thyroid tumors are either benign (noncancerous) or malignant (cancerous) growths. Examples of benign tumors are adenomas, which may secrete thyroid hormone. Thyroid adenomas. Thyroid adenomas are small growths (nodules) that start in the cell layer that lines the inner surface of the thyroid gland. The adenoma itself may secrete thyroid hormone.
