Overview of Typical Thyroid Cancer Treatment

Females are more likely to have thyroid cancer at a ratio of three to one. Thyroid cancer can occur in any age group, although it is most common after age 30, and its aggressiveness increases significantly in older patients. The majority of patients present with a nodule on their thyroid that typically does not cause symptoms.
Thyroid cancer is usually diagnosed by sticking a needle into a thyroid nodule or removal of a worrisome thyroid nodule by a surgeon.

- The removed thyroid nodule is looked at under a microscope by a pathologist who will then decide if the nodule is benign (95-99% of all nodules that are biopsied) or malignant (less than 1% of all nodules, and about 1-5% of nodules that are biopsied).
- The pathologist decides the type of thyroid cancer: papillary, follicular, mixed papilofollicuar, medullary, or anaplastic.
- The entire thyroid is surgically removed; sometimes this is done during the same operation where the biopsy takes place. He/she will assess the lymph nodes in the neck to see if they also need to be removed. In the case of anaplastic thyroid cancer, your doctor will help you decide about the possibility of a tracheostomy.
- About 4-6 weeks after the thyroid has been removed, the patient will undergo radioactive iodine treatment. This is very simple and consists of taking a single pill in a dose that has been calculated for the patient. – The patient goes home and avoids contact with other people for a couple of days (so they are not exposed to the radioactive materials).
- A week or two after the radioactive iodine treatment the patient begins taking a thyroid hormone pill. No one can live without thyroid hormone, and if the patient doesn’t have a thyroid anymore, he or she will take one pill per day for the rest of their life. This is a very common medication.
- Every 6-12 months the patient returns to his endocrinologist for blood tests to determine if the dose of daily thyroid hormone is correct and to make sure that the thyroid tumor is not coming back. The frequency of these follow up tests will vary greatly from patient to patient.
- Endocrinologists are typically quite good at this and will typically be the type of doctor that follows this patient long-term.

Types of Thyroid cancer and its symptoms

Thyroid cancer is a cancerous growth of the thyroid gland. The thyroid is a butterfly-shaped gland located at the base of the neck. It produces hormones that regulate the heart rate, blood pressure, body temperature and weight. There are several types of thyroid cancer :

- Papillary thyroid cancer : The papillary type of thyroid cancer is the most common, making up about 80 percent of all thyroid cancer diagnoses. Papillary thyroid cancer can occur at any age, but is most commonly diagnosed in people ages 30 to 50.
- Follicular thyroid cancer : Follicular thyroid cancer also includes Hurthle cell cancer. Follicular thyroid cancer typically occurs in people older than 50. (An estimated 11% of all thyroid cancer cases).
- Medullary thyroid cancer accounts for 5 to 10 percent of thyroid cancer cases. It arises in C cells, not follicular cells. Medullary thyroid cancer is easier to control if it is found and treated before it spreads to other parts of the body.
- Anaplastic thyroid cancer is the least common type of thyroid cancer (only 1 to 2 percent of cases). It arises in the follicular cells. The cancer cells are highly abnormal and difficult to recognize. This type of cancer is usually very hard to control because the cancer cells tend to grow and spread very quickly.
- Thyroid lymphoma : Thyroid lymphoma begins in the immune system cells in the thyroid. Thyroid lymphoma is very rare. It occurs most often in adults age 70 or older.

These rarer types of thyroid cancer are usually more aggressive, with a higher chance of spreading to another part of the body (metastasis).

Symptoms of Thyroid Cancer

- Cough
- Difficulty swallowing
- Enlargement of the thyroid gland
- Hoarseness or changing voice
- Neck swelling
- Thyroid lump (nodule)
