Thyroid nodule The prevalence of cancer is higher in males, patients under 20 years old or over 70 years old, and patients with a history of head and neck irradiation or a family history of thyroid cancer. Solitary thyroid nodule Risks for cancer. Solitary thyroid nodules are more common in females yet more worrisome in males. Other associations with neoplastic nodules are family history of thyroid cancer and prior radiation to the head and neck. Most common cause of solitary thyroid nodule is benign colloid nodules and second most common cause is follicular adenoma. Radiation exposure to the head and neck may be for historic indications such as tonsillar and adenoid hypertrophy, enlarged thymus, acne vulgaris, or current indications such as Hodgkin's lymphoma.

What are the types of thyroid nodules? Cancerous nodules are classified by the types of malignant thyroid cells they contain. These cell types include papillary, follicular, medullary, or poorly differentiated (anaplastic) cells. The prognosis for the patient depends largely on the cell type and how far the cancer has spread by the time it is discovered. In addition to thyroid cancer of the cell types mentioned, thyroid nodules may contain lymphoma, a cancer of the immune system. Cancer from other sites, such as breast and kidney, also can spread (metastasize) to the thyroid gland. The cause of most thyroid nodules is not known. In certain cases, a lack of iodine in the diet can cause the thyroid gland to develop ...

- There are two types of swelling of the thyroid gland: diffuse goiter in which the entire thyroid gland is swollen like in Graves' disease or Hashimoto's disease and nodular goiter in which part of the thyroid gland is enlarged like a lump.

Overactive thyroid: Hyperthyroidism Thyroid nodule. One or more lumps, or nodules, can grow in the thyroid gland, gradually increasing the gland's activity and the amount of thyroid hormone in your blood. 1  If one nodule causes hyperthyroidism, it is called a single toxic nodule.

Thyroid Nodules 1 The main function of the thyroid gland in the neck is to make thyroid hormone, which is essential for normal growth and metabolism. 2  Nodules are simply lumps which are either solid or fluid-filled. 3  Goiter is simply a term for an enlarged thyroid gland.

Goiter & Thyroid Nodules A thyroid nodule is simply a lump or mass in the thyroid gland. Thyroid nodules are relatively common; 6% of adult women and 2% of adult men in the U.S. have a thyroid nodule that can be felt on examination. Goiter can be the result of thyroid tumors, which are usually benign, but sometimes malignant. 2  Most thyroid tumors present as discrete nodules, but there are several kinds of thyroid cancer that can cause generalized swelling of the gland.

- Thyroid nodules are fairly common, but when your doctor discovers one, it can be a nerve- wracking process for you in terms of deciding how to proceed. Typically, nodules are evaluated using ultrasound, and in some cases, a fine needle biopsy process, to rule out the small chance that the nodule is cancerous.

- 1 Thyroid cancer: An uncommon form of cancer, thyroid cancer is usually curable. 2  Surgery, radiation, and hormone treatments may be used to treat thyroid cancer. 3  Thyroid nodule: A small abnormal mass or lump in the thyroid gland. 4  Thyroid nodules are extremely common.ll rights reserved. The thyroid is a butterfly-shaped gland that sits low on the front of the neck. Your thyroid lies below your Adam’s apple, along the front of the windpipe. The thyroid has two side lobes, connected by a bridge (isthmus) in the middle.

- Radiology Description. 1  Microcalcifications (< 2 mm and without acoustic shadow by ultrasound) in thyroid nodules are usually psammoma bodies. 2  Macrocalcifications (≥ 2 mm and with acoustic shadow) are secondary to tumor necrosis and can be seen in both benign and malignant nodules.

- The word lump may first remind you of cancer. A lump (nodule) found in the thyroid gland can be classified as a tumor, either benign (noncancerous) or malignant (cancerous), or as hyperplasia, which looks similar to tumor but is totally different from a histological point of view.

Thyroid Gland: Frequently Asked Questions A thyroid nodule is a growth within the thyroid gland, which may or may not be felt by physical exam. Some nodules are only found incidentally on imaging of the thyroid. Thyroid nodules are very common and by age 60 almost one-half of all people will have a thyroid nodule.

Thyroid Cancer Thyroid cancer: Cancer of the gland in front of the neck that normally produces thyroid hormone which is important to the normal regulation of the metabolism of the body. There are 4 major types of thyroid cancer -- papillary, follicular, medullary, and anaplastic. The most common symptom of thyroid cancer is a lump, or nodule, that can be felt in the neck. The only certain way to tell whether a thyroid lump is cancer is by examining the thyroid tissue, obtained using a needle or surgery to obtain a biopsy. Carcinoma of the thyroid gland is an uncommon cancer but is the most common malignancy of the endocrine (hormone making)system. Differentiated tumors (papillary or follicular) are highly treatable and usually curable.

Overview Several conditions can cause nodules to develop in your thyroid gland: 1  Iodine deficiency. 2  Lack of iodine in your diet can sometimes cause your thyroid gland to develop thyroid nodules. 3  But iodine deficiency is uncommon in the United States, where iodine is routinely added to table salt and other foods. Goiter is a term used to describe any enlargement of the thyroid gland, which can be caused by iodine deficiency or a thyroid disorder. 2  A multinodular goiter contains multiple distinct nodules within the goiter, but its cause is less clear.

Types of thyroid cancer Anaplastic carcinoma is the most undifferentiated type of thyroid cancer, meaning that it looks the least like normal cells of the thyroid gland. As a result, it is a very aggressive form of cancer that quickly spreads to other parts of the neck and body. It occurs in approximately 2 percent of thyroid cancer cases.

- Nodules that appear suddenly are typically fluid-filled cysts and are often benign. They can be evaluated with a noninvasive ultrasound exam. If blood tests indicate that the nodules are producing excess thyroid hormone, your doctor may treat you for hyperthyroidism.

- Basic Facts about Thyroid Nodules. Simply put, thyroid nodules are lumps that commonly arise within an otherwise normal thyroid gland. Often these abnormal growths of thyroid tissue are located at the edge of the thyroid gland, so they can be felt as a lump in the throat.

Thyroid Nodules Thyroid Nodules. The thyroid gland is located in the lower front of the neck, below the voicebox (larynx) located in the upper part of the neck, and above the collarbones. A thyroid nodule is a lump in or on the thyroid gland. Thyroid nodules are common and detected in about six percent of women and one to two percent of men; they are less common in younger patients and occur 10 times as often in older individuals, but are usually not diagnosed.

Lab Tests and Nodules People with thyroid nodules that are possibly cancer usually have normal levels of thyroid hormone. Also, most people with low or high levels of thyroid hormone do not have cancer. Thyroid disorders involving low or high thyroid hormone levels are much more common than thyroid cancer.

Goiter & Thyroid Nodules Enlargement of the thyroid (goiter) and lumps within it (nodules) are both relatively common. They may be obvious to the naked eye or can be found incidentally by imaging studies of the neck, such as a sonogram of the carotid arteries or a CT or MR of the spine.

Thyroid cysts most commonly result from degenerating thyroid adenomas, which are benign, but they occasionally contain malignant solid components. Diagnosis. After a nodule is found during a physical examination, a referral to an endocrinologist, a thyroidologist or otolaryngologist may
