Oncology. Thyroid neoplasm is a neoplasm or tumor of the thyroid. It can be a benign tumor such as thyroid adenoma, [ 1] or it can be a malignant neoplasm ( thyroid cancer ), such as papillary, follicular, medullary or anaplastic thyroid cancer. [ 2] Most patients are 25 to 65 years of age when first diagnosed; women are more affected than men ...
At the cellular level, T 3 is the body's more active and potent thyroid hormone. [2] T 3 helps deliver oxygen and energy to all of the body's cells, its effects on target tissues being roughly four times more potent than those of T 4. [2] Of the thyroid hormone that is produced, just about 20% is T 3, whereas 80% is produced as T 4.
A circulating tumor cell ( CTC) is a cell that has shed into the vasculature or lymphatics [ 1] from a primary tumor and is carried around the body in the blood circulation. CTCs can extravasate and become seeds for the subsequent growth of additional tumors ( metastases) in distant organs, a mechanism that is responsible for the vast majority ...
31,900 (2015) [ 7] Thyroid cancer is cancer that develops from the tissues of the thyroid gland. [ 1] It is a disease in which cells grow abnormally and have the potential to spread to other parts of the body. [ 8][ 9] Symptoms can include swelling or a lump in the neck. [ 1]
Follicular thyroid cancer accounts for 15% of thyroid cancer and occurs more commonly in women over 50 years of age. Thyroglobulin (Tg) can be used as a tumor marker for well-differentiated follicular thyroid cancer. Thyroid follicular cells are the thyroid cells responsible for the production and secretion of thyroid hormones .
Breast cancer classification divides breast cancer into categories according to different schemes criteria and serving a different purpose. The major categories are the histopathological type, the grade of the tumor, the stage of the tumor, and the expression of proteins and genes. As knowledge of cancer cell biology develops these ...
Medullary thyroid cancer is a form of thyroid carcinoma which originates from the parafollicular cells (C cells), which produce the hormone calcitonin. [ 1] Medullary tumors are the third most common of all thyroid cancers and together make up about 3% of all thyroid cancer cases. [ 2] MTC was first characterized in 1959.
Thyroid follicular cells (also called thyroid epithelial cells or thyrocytes[ 1]) are the major cell type in the thyroid gland, and are responsible for the production and secretion of the thyroid hormones thyroxine (T 4) and triiodothyronine (T 3 ). They form the single layer of cuboidal epithelium that makes up the outer structure of the ...
