Why it's done

Your doctor may recommend a thyroidectomy if you have 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.
• Indeterminate or suspicious thyroid nodules. Some thyroid nodules can't be identified as cancerous or noncancerous after testing a sample from a needle biopsy. Doctors may recommend that people with these nodules have thyroidectomy if the nodules have an increased risk of being cancerous.
