A thyroid cancer, the butterfly-shaped gland at the base of the neck, treatable by a medical professionalRequires a medical diagnosisLaboratory tests or imaging are always requiredThe cause of thyroid cancer is not well understood, but it may involve a combination of genetic and environmental factors, people do not have symptoms. Others may notice a lump in the neck. Treatments, which are generally successful, include surgery, hormonal therapy, radioactive iodine, radiation and, in some cases, chemotherapy. Thyroid cancer is a growth of cells that begins in the thyroid.
The thyroid is a butterfly-shaped gland located at the base of the neck, just below the Adam's apple. The thyroid produces hormones that regulate heart rate, blood pressure, body temperature, and weight. Thyroid cancer often presents as a lump or lump in the thyroid and usually causes no other symptoms (see the Thyroid Nodules brochure). Blood tests usually don't help detect thyroid cancer, and thyroid blood tests, such as TSH, are usually normal, even when cancer is present.
A doctor's neck exam is a common way in which thyroid nodules and thyroid cancer are found. Thyroid nodules are often discovered accidentally on imaging tests, such as CT scans and neck ultrasounds, which are performed for reasons You may have found a thyroid nodule by noticing a lump in your neck while looking in a mirror, buttoning your neck, or fastening a necklace. Rarely, cancers and thyroid nodules can cause symptoms. May complain of pain in the neck, jaw, or ear.
If a lump is large enough to compress the trachea or esophagus, it can cause difficulty breathing, swallowing, or cause a “tickling” sensation in the throat. Even less often, you can develop hoarseness if thyroid cancer invades the nerve that controls the vocal cords. Thyroid cancer is a rare type of cancer that affects the thyroid gland, a small gland at the base of the neck that produces hormones. Thyroid cancer is a rare type of cancer that affects the thyroid gland, a small gland located at the base of the neck.
For information on childhood thyroid cancer, see the PDQ summary on Childhood Thyroid Cancer Treatment. Because only thyroid tissue absorbs iodine, RAI destroys thyroid tissue and thyroid cancer cells without damaging other tissues. Helps explain the number of people diagnosed with thyroid cancer and overall survival rates. Anaplastic thyroid cancer is the most advanced and aggressive thyroid cancer and the one that is least likely to respond to treatment.
In addition, because thyroid cancer treatment kills thyroid cells, the thyroid cannot produce enough thyroid hormone. Differentiated thyroid cancers (DTCs) are treated by a combination of surgery to remove the thyroid gland (thyroidectomy) and a type of radiation therapy that kills any remaining cancer cells and prevents thyroid cancer from returning. Your healthcare provider can discuss the best treatment option for the type of thyroid cancer you have. Recent studies even suggest that if you have a small tumor that measures less than 1 cm in diameter, called papillary thyroid microcarcinoma, you may be seen very safely without surgery.
If part or all of the thyroid gland is removed, it will no longer be able to produce the hormones that regulate the metabolic system. It is estimated that between 5 and 20% of people with a history of thyroid cancer will experience a return of cancer cells in the neck. The extent of surgery will depend on the size of the tumor and whether or not the tumor has spread beyond the thyroid gland. Thyroid cancer can only be diagnosed with certainty after the nodule has been surgically removed (see the Thyroid Nodules brochure).
Sometimes, a drug that blocks the effects of radiation on the thyroid is given to people who live near nuclear power plants in the United States. With this information, doctors may decide to do a biopsy to remove a small sample of thyroid tissue. .
