Keller Endocrinologist Doctors for Thyroid Nodules
Type of Physician: Endocrinologist
What is a Endocrinologist?
A subspecialty certification by the Board of Internal Medicine; practitioners treat disorders of the internal (endocrine) glands such as the thyroid and adrenal glands. Endocrinology also deals with disorders such as diabetes, metabolic and nutritional disorders, pituitary diseases, and menstrual and sexual problems.

The term "thyroid nodule" refers to any abnormal growth that forms a lump in
the thyroid gland.
The thyroid gland is located low in the front of the neck, below the Adam's
apple. The gland is shaped like a butterfly and wraps around the windpipe or
trachea. The two wings or lobes on either side of the windpipe are joined
together by a bridge, called the isthmus, which crosses over the front of
the windpipe.
A thyroid nodule can occur in any part of the gland. Some nodules can be
felt quite easily, while others can be hidden deep in the thyroid tissue or
located very low in the gland where they are difficult to feel.
What is the prevalence of thyroid nodules and cancer?
These days, with modern imaging studies such as
ultrasound (US),
computerized tomography (CT), and magnetic resonance imaging (MRI), more and
more thyroid nodules are being found incidentally. This means the nodules
are found during studies that are being done for reasons other than
examination of the thyroid gland. It is estimated that 4-8%
of adult women and 1-2% of adult men have thyroid nodules that can be felt
on physical examination, but closer to 30% of women have nodules detectable
by ultrasound. In fact, the diagnosis of a thyroid nodule is the most common
endocrine problem in the United States.
Although the majority of thyroid
nodules are benign (not cancerous), about 10% of nodules do contain cancer
.
Therefore, the primary purpose for
evaluating a thyroid nodule is to determine whether cancer is present.
What are the symptoms of thyroid nodules?
The vast majority of thyroid nodules do not cause symptoms. However, if the
cells in the nodules are functioning and producing thyroid hormone on their
own, the nodule may produce signs and symptoms of too m...
When I was asked to write an article on "thyroid disease", I took a very deep
breath. The task seemed daunting. As any Endocrinologist (hormone specialist)
knows, there are many subtopics within this giant topic, and an article like
this could go on for a hundred pages! So, once I caught my breath, I decided to
simply design this article to present a "rough guide" to the thyroid. This
article will be an outline or introduction to many conditions that involve the
thyroid gland. As you read through this, you will find a number of links that
will take you to more in-depth articles dealing with the specific topic in
question.
Thyroid 101: What is the thyroid and what does it do?
The thyroid is a butterfly-shaped gland located in the
front of the neck just
below the Adams apple. The gland wraps around the windpipe (trachea) and has a
shape that is similar to a butterfly ...

Hypothyroidism is any state in which thyroid hormone production is below normal. Normally, the
rate of thyroid hormone production is controlled by the brain at the pituitary.
Hypothyroidism is a very common condition and the symptoms of hypothyroidism are
often subtle.
Hyperthyroidism is an excess of thyroid hormone resulting from an overactive thyroid gland. Symptoms can include increased heart rate, weight
loss, depression, and cognitive slowing. Treatment is by medication, the use of
radioactive iodine, thyroid surgery, or reducing the dose of thyroid hormone.
There are four major types of thyroid cancer: papillary, follicular, medullary, and anaplastic thyroid cancer. Tumors on the thyroid are referred to as thyroid nodules. Symptoms of thyroid cancer include swollen lymph nodes, pain in the throat, difficulty swallowing, hoarseness, and a lump near the Adam's apple. Treatment usually involves chemotherapy, surgery, radioactive iodine, hormone treatment or external radiation and depends upon the type of thyroid cancer, the patient's age, the tumor size, and whether the cancer has metastasized.
Hashimoto's thyroiditis is the most common cause of hypothyroidism in the US. This conditions is caused by inflammation of the thyroid gland. Symptoms may include: fatigue, weight gain, cold intolerance, excessive sleepiness, dry or coarse hair, difficulty swallowing, a lump in the front of the throat, and many more. Treatment is usually hypothyroid medication.
There are many types of thyroid disease. Some occur due to the function of the thyroid itself such as hypothyroidism, hyperthyroidism, Hashimoto's thyroiditis, etc. Some causes of thyroid disease occur due to problems with the structure of the thyroid gland such as goiters, thyroid nodules, and thyroid cancer. Treatment of thyroid disease depends on the cause of the disease.
Thyroiditis is the inflammation of the thyroid gland. The inflamed thyroid gland can release an excess of thyroid hormones into the blood stream, resulting in a temporary hyperthyroid state. Some forms of thyroiditis can be diagnosed based on tenderness and enlargement of the thyroid gland. A thyroid scan sometimes is used in making the diagnosis. Thyroiditis can also be diagnosed with a biopsy of the thyroid gland.
The thyroid gland is found in the neck just below the "Adam's apple." This gland is responsible for producing thyroid hormone, which is an important hormone that stimulates the metabolism of the body. Between 4% and 7% of people in the United States have lumps (or nodules) in their thyroid gland that can be felt on examination. Like many things, the thyroid gland gets "lumpier" as we get older and the frequency of these nodules increases with age. In fact, many are found incidentally during routine examinations or radiology testing. Thyroid nodules are also more common in women than in men. In fact, ultrasound studies have found that up to one in every three women has at least one thyroid nodule that may be too small to notice. (Usually, a nodule needs to be greater than one centimeter in diameter for it to be felt.). Interestingly, because women have so many more nodules than men, the incidence of detected cancer is higher in women then in men by...
