Anatomy And Physiology : Thyroid Cancer

So today I decided to go with my good buddy Isaac to a support group for teens with Cancer. As the group was starting I saw this beautiful figure of a young lady. As the groups shared information about each other she said her name was Hazel Grace Lancaster and was a fighter against Thyroid Cancer In her lungs. This form of Thyroid Cancer causes fluids to flood the lungs stopping them from breathing. So after the meeting was over, Hazel-Grace and I went outside and talked for a while. We chatted about school and how we both are coping with cancer. As time went on I put a cigarette in my mouth, which made her mad. After she finished yelling at me for having a cig in my mouth I told her it’s a metaphor. ( Putting the thing

The thyroid is a butterfly-shaped gland. You would find it located in the lower neck, right below the Adam’s apple. The location is the same in both men and women. What the thyroid does is create and store thyroid hormone. It then releases the hormone in appropriate amounts to keep the body’s metabolism functioning at a normal level. If there is too much thyroid hormone, this is known as hyperthyroidism. In hyperthyroidism, the body’s metabolism increases. This condition can cause high blood pressure, high heart rate, nervousness, palpitations, and severe weight loss. Too little thyroid hormone, on the other hand, can cause tiredness, depression, memory loss, dry skin, brittle hair, and weight gain—among many other symptoms.

Anaplastic thyroid carcinoma (ATC) is the rarest, most devastating form of thyroid malignancy. Also known as undifferentiated thyroid carcinoma, it makes up only 1-2% of all thyroid cancers but is responsible for the majority of thyroid cancer-related deaths3,9,10.

The symptoms are initially asymptomatic they begin to appear such as swelling in the neck, swelling in the lymph nodes and pain, hoarseness and difficulty to breath. The causes are exposure to high levels of radiation, inherited genetic syndromes. There are four types of thyroid cancer: papillary, medullary thyroid cancer, anaplastic thyroid cancer, thyroid lymphoma. According to cancercenters Papillary carcinoma is the most common type of thyroid cancer, accounting for approximately 80% of cases. Papillary carcinomas are slow growing, differentiated cancers that develop from follicular cells and can develop in one or both lobes of the thyroid gland. This type of cancer may spread to nearby lymph nodes in the neck, but it is generally treatable with a good prognosis (outlook for survival). Follicular carcinoma is the second most common type of thyroid cancer, and accounts for approximately one out of 10 cases. It is found more frequently in countries with an inadequate dietary intake of iodine. Follicular carcinoma is also a differentiated form of thyroid cancer. In most cases, it is associated with a good prognosis, although it is somewhat more aggressive than papillary cancer. Follicular carcinomas do not usually spread to nearby lymph nodes, but they are more likely than papillary cancers to spread to other organs, like the lungs or the bones. Hurtle cell carcinoma, also known as oxyphil cell carcinoma, is a subtype of follicular carcinoma, and accounts for approximately 3 percent of all thyroid cancers. Medullary thyroid carcinoma develops from C cells in the thyroid gland, and is more aggressive and less differentiated than papillary or follicular cancers. Approximately 4 percent of all thyroid cancers will be of the medullary subtype. These cancers are more likely to spread to lymph nodes and other organs, compared with the more differentiated thyroid cancers. They also frequently

Thyroid nodules, or lumps, are very common. They occur in over half of the world's population, but only 5 per cent of them are cancerous. Nodules are referred to as either 'hot' or 'cold,' depending on the amount of radioactive iodine it concentrates, or takes up, when testing for the type of nodule it is.

Most are common only around 5% coming to be cancerous. Most times when a person has a thyroid nodule they have no symptoms. If the nodule is causing your glands to make too many hormones it can cause what is called hyperthyroidism. Symptoms of this include palpitations, rapid heart rate, anxiety, restlessness and an increased appetite. If your doctor suspects thyroid nodules they will do tests such as an ultrasound or a thyroid scan. A good example of a procedure done by an endocrinologist is an LHRH test. This test is done to see how your pituitary gland is working when it comes to regulating sex hormone production. The night of this procedure you are to not eat or drink anything. When you go in, you will be made comfortable and have a small needle inserted into a vein in your hand or arm. This is just to get a blood sample and is not to stay. Whoever is taking the blood will use a needle such as a ventflon to make drawing the blood sample easy with little to no discomfort. The blood is then checked for hormones LH and LSH then you get an injection to make the levels of those hormones rise. You will have blood drawn twice. Once each after 30

Follicular Thyroid cancer is the second most common type to get. If you were to get thyroid cancer, It would be most likely that you would get follicular thyroid cancer. It is rare that you would get this cancer due to radiation exposure. This cancer is known to spread to the veins arteries and thyroid gland. This type of cancer is more common in females than males on a 3 to 1 ratio. If you were to get this cancer you’re most likely to be between ages 40 and 60.

The thyroid gland is the gland that makes and stores hormones that help regulate the heart rate, blood pressure, body temperature, and metabolism. Thyroid hormones are essential for the function of every cell in the body. They help regulate growth and the rate of chemical reactions in the body. Thyroid hormones also help children grow and develop. The thyroid gland is located in the lower part of the neck, below the Adam's apple, wrapped around the trachea. It has the shape of a butterfly with two lobes attached to one another by a middle part called the isthmus. The thyroid uses iodine, a mineral found in some foods and in iodized salt, to make its hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine

A thyroid nodule is an isolated growth of thyroid cells that forms a lump in your thyroid gland. The thyroid gland is a butterfly-shaped gland. It is found in the lower front of your neck. This gland sends chemical messengers (hormones) through your blood to all parts of your body. These hormones are important for regulating your body temperature and helping your body use energy. Thyroid nodules are common. Most are not cancerous (benign). You may have one or several nodules.

Most thyroid tumors can be readily diagnosed using histopathologic criteria, which allow the pathologist to differentiate benign from malignant lesions and guarantee an accurate classification for the majority of the variants of carcinomas derived from follicular epithelial cells. However, in most cases, the pathologist is confronted with thyroid lesions in which the distinction between benign and malignant can be quite subtle. The decision favoring one or another has clinical consequences and implies different modalities of treatment. For this reason, the approach to these challenging tumors should include ancillary techniques, immunohistochemistry and molecular profiling, that can improve the standard morphologic assessment (3).

Thyroid nodules are lumps in the thyroid often called adenomas. These adenomas are quite common affecting around seven percent our countries population. These lumps on the thyroid can become very active and thus produce a large amount of thyroid hormone. In some cases hyperthyroidism is brought on by consuming too much medication that treats an underactive thyroid.

At this time, it is not clear how much diagnostic radiation is contributing to the increase in thyroid cancer cases. It is possible that the increase in the diagnosis of thyroid cancer can be attributed to a greater rate of detection by use of ultrasonography and fine needle aspiration3. The thyroid tissue itself is among the tissues that are less sensitive to radiation, however, thyroid cancer is still such a concern because the thyroid is so superficial in the body1 (77). “Even doses as small as 50–100 mGy have been associated with an increased risk of thyroid malignancy in children, with a

Someone from the Colorado School of Medicine noticed that the cell lines made by Ain had been contaminated or misinterpreted, some even changed by other cancer cells.

The differentiation of single benign nodule and malignant one is considered an important goal. Early diagnosis of thyroid cancer avoids unneeded surgery in those complaining of benign nodules and decreases both mortality and morbidity rates of the disease (2).
