PARATHYROID CARCINOMA Meaning and
Definition
-
Parathyroid carcinoma is a rare malignant tumor that develops in the parathyroid glands, a small set of four pea-sized glands located near the thyroid gland in the neck. These glands produce parathyroid hormone (PTH), which helps regulate calcium levels in the body. Parathyroid carcinoma is characterized by the uncontrolled growth and division of abnormal cells within the parathyroid glands.
Typically, parathyroid carcinoma is a slow-growing tumor that can cause an excessive production of PTH, resulting in elevated blood calcium levels, a condition known as hypercalcemia. Symptoms of parathyroid carcinoma often include bone pain, fractures, kidney stones, increased urination, abdominal pain, fatigue, and weakness.
Diagnosis of parathyroid carcinoma involves a combination of imaging tests, blood tests to measure PTH and calcium levels, as well as a biopsy or surgical removal of the tumor. Treatment options for parathyroid carcinoma include surgical removal of the affected parathyroid gland(s), along with neighboring lymph nodes, and possibly parts of the thyroid gland. In some cases, radiation therapy or chemotherapy may be recommended to help destroy any remaining cancer cells.
Prognosis for parathyroid carcinoma can vary widely depending on the stage and size of the tumor at the time of diagnosis. Generally, parathyroid carcinoma has a high rate of recurrence, and the outcome may be influenced by factors such as the extent of tumor spread, the presence of metastasis, and the effectiveness of treatment. Prompt diagnosis and early intervention are crucial for improving the prognosis of parathyroid carcinoma patients.
Etymology of PARATHYROID CARCINOMA
The word "parathyroid carcinoma" can be broken down into its etymological components as follows:
1. Parathyroid: The term "parathyroid" consists of two parts - "para-" and "thyroid".
- "Para-" is a prefix derived from the Greek word "para", meaning "beside" or "near". In medical terminology, "para-" is typically used to indicate something that is alongside or adjacent to something else.
- "Thyroid" refers to the thyroid gland, an endocrine gland located in the neck. The word "thyroid" comes from the Greek word "thyreoeidēs", meaning "shield-shaped", as the thyroid gland has a shape resembling a shield.
2. Carcinoma: The term "carcinoma" is derived from the Greek word "karkinos" meaning "crab", referring to the crab-like appearance of certain tumors.
