A thyroidectomy may be recommended for conditions such as:
- Thyroid cancer. Cancer is the most common reason for thyroidectomy. If you have thyroid cancer, removing most, if not all, of your thyroid will likely be a treatment option.
- Noncancerous enlargement of the thyroid (goiter). Removing all or part of your thyroid gland is an option if you have a large goiter that is uncomfortable or causes difficulty breathing or swallowing or, in some cases, if the goiter is causing hyperthyroidism.
- Overactive thyroid (hyperthyroidism). Hyperthyroidism is a condition in which your thyroid gland produces too much of the hormone thyroxine. If you have problems with anti-thyroid drugs and don't want radioactive iodine therapy, thyroidectomy may be an option.
