Thyroid cancer is a type of cancer that affects the thyroid gland. The thyroid gland is located in the neck and produces hormones that regulate metabolism. If left untreated, thyroid cancer can spread to other parts of the body. There are several synonyms for thyroid cancer, including thyroid carcinoma, thyroid malignancy, and thyroid neoplasm. These terms are often used interchangeably to describe the same condition and can help to make discussions about thyroid cancer more clear and concise. It is important to be familiar with these terms if you or someone you know has been diagnosed with thyroid cancer, as they may come up frequently in medical discussions and research.
