Thyroid Cancer
Overview
Thyroid cancer begins in the cells of the thyroid, a small butterfly-shaped gland at the base of the neck that helps regulate metabolism, heart rate, body temperature, and other essential functions. It is often found early, sometimes during imaging for unrelated concerns, and many thyroid cancers grow slowly. Others can be more aggressive, but most cases are highly treatable with prompt, appropriate care. While rates of diagnosis have increased in recent years, this is largely due to improved imaging technology that can detect very small thyroid tumors that may not have been identified in the past.
Signs & Symptoms
Thyroid cancer often develops without noticeable symptoms in the early stages. As the tumor grows, you may experience:
- A lump or nodule that can be felt in the neck
- Hoarseness or changes in your voice
- Difficulty swallowing
- Pain or discomfort in the neck or throat
- Swollen lymph nodes in the neck
If you notice any persistent changes in your neck or voice, it is important to talk with your provider so the cause can be evaluated.
Causes
The exact cause of thyroid cancer is not known. Thyroid cancer develops when cells in the thyroid undergo genetic changes that allow them to grow and divide faster than they should. These abnormal cells do not die when they are supposed to, and over time they build up to form a tumor. Cancer cells can also spread into nearby tissues and travel to other areas of the body.
Types of Thyroid Cancer
Thyroid cancer is classified by the type of cell where it begins. Identifying the type helps guide treatment and provides important information about what to expect. Common types include:
The most common type, papillary thyroid cancer starts in the follicular cells that produce thyroid hormones. It can occur at any age but is most often diagnosed in people in their 30s to 50s. Papillary and follicular thyroid cancers are often grouped together as differentiated thyroid cancers.
Also beginning in the follicular cells, this type is more often found in older adults. A rare subtype called Hurthle cell cancer can behave more aggressively.
Medullary thyroid cancer develops in the C cells of the thyroid, which make the hormone calcitonin. Higher-than-normal calcitonin levels can help detect this cancer early. Some cases are linked to inherited genetic conditions.
A rare but fast-growing form, anaplastic thyroid cancer also starts in the follicular cells. It is more common in adults over age 60 and is usually more challenging to treat.
Less common cancers can develop in the thyroid, including thyroid lymphoma, which starts in immune system cells, and thyroid sarcoma, which begins in connective tissue cells.
Treatments
Treatment Options
Treatment for thyroid cancer depends on the type of cancer, its stage, and your overall health. Most thyroid cancers are highly treatable, and many are curable. Care typically includes one or a combination of the following:
