Operations involve removal of the thyroid gland (thyroidectomy) either as a part of the gland (lobectomy or hemithyroidectomy), or the whole gland (total thyroidectomy). Incomplete resections (sub-total or near total thyroidectomy) are also infrequently performed, but are disfavored by most surgeons [ citation needed ] .
A thyroidectomy is an operation that involves the surgical removal of all or part of the thyroid gland. In general surgery, endocrine or head and neck surgeons often perform a thyroidectomy when a patient has thyroid cancer or some other condition of the thyroid gland (such as hyperthyroidism) or goiter. Other indications for surgery include ...
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.
Tumor size, type, and location are major factors as to whether a lobectomy is performed. This can be due to cancer or smoking. Lung lobectomies are performed on patients as young as eleven or twelve who have no cancer or smoking history, but have conditions from birth or early childhood that necessitate the operation.
Parathyroid carcinoma is sometimes diagnosed during surgery for primary hyperparathyroidism. If the surgeon suspects carcinoma based on severity or invasion of surrounding tissues by a firm parathyroid tumor, aggressive excision is performed, including the thyroid and surrounding tissues as necessary.

Most common causes of hyperthyroidism by age. [6]A thyroid adenoma is distinguished from a multinodular goiter of the thyroid in that an adenoma is typically solitary, and is a neoplasm resulting from a genetic mutation (or other genetic abnormality) in a single precursor cell. [7]
Thyroid cancer accounts for less than 1% of cancer cases and deaths in the UK. Around 2,700 people were diagnosed with thyroid cancer in the UK in 2011, and around 370 people died from the disease in 2012. [69] However, in South Korea, thyroid cancer was the 5th most prevalent cancer, which accounted for 7.7% of new cancer cases in 2020. [70]
