Thyroid cancer is one of the more treatable types of cancer, and many people diagnosed with it have a very good chance of recovery.
Most cases are found early, when the cancer is small and growing slowly. Recent changes in how doctors treat thyroid cancer—especially low-risk types—are helping patients avoid unnecessary surgery and feel more confident about their care.
The thyroid is a small, butterfly-shaped gland in the front of your neck. It helps control your body’s metabolism, which is how your body uses energy. Thyroid cancer happens when cells in this gland start growing out of control. Most of the time, thyroid cancer is found as a lump in the neck during a check-up or on a scan done for another reason. These lumps usually don’t hurt.
There are different types of thyroid cancer. The most common ones are called differentiated thyroid cancers, or DTC. These include papillary, follicular, and oncocytic cancers. They grow slowly and are usually easy to treat.
In fact, about 90% of thyroid cancer cases are DTC. Less common types—like anaplastic, poorly differentiated, or medullary thyroid cancer—are more serious and grow faster. These rare types need special treatments.
Papillary thyroid cancer makes up about 84% of cases. It starts in the thyroid cells that produce hormones. Follicular and oncocytic cancers are less common but can be a bit more aggressive. Medullary and anaplastic cancers are rare and harder to treat.
Most people with DTC live a long time after diagnosis, especially if the cancer is found early. Even if the cancer has spread, many people still live for many years with the right treatment.
There’s no routine screening test for thyroid cancer, and many people don’t notice any symptoms. But when symptoms do appear, they might include a painless lump in the neck, trouble swallowing, hoarseness, or swollen lymph nodes. Pain or a sudden change in voice might suggest a faster-growing cancer, but these signs are rare.
Doctors don’t always know what causes thyroid cancer. Some risk factors include having had radiation to the head or neck, a family history of thyroid cancer, or certain inherited genetic conditions. Thyroid cancer is more common in women and usually appears in middle age, although it can affect anyone.
Treatment depends on the type, size, and stage of the cancer. Many low-risk patients can have just part of their thyroid removed (called a lobectomy).
The latest guidelines from the American Thyroid Association recommend less aggressive treatments for low-risk cases. Doctors now prefer lobectomy over removing the whole thyroid unless necessary. They also reserve radioactive iodine (RAI) therapy for higher-risk cases only.
Some very small cancers without concerning features can even be monitored instead of removed right away. This is called active surveillance. A newer option being studied is radiofrequency ablation (RFA), where a small probe heats and shrinks the nodule using sound waves, without surgery.
For people with more advanced thyroid cancer, treatments may include complete thyroid removal, RAI, and sometimes external radiation or chemotherapy. When standard treatments don’t work, newer therapies are available.
Targeted therapy uses drugs that attack only cancer cells. Immunotherapy boosts the body’s immune system to fight cancer more effectively. Molecular testing helps doctors choose the right treatment by analyzing the cancer’s unique features.
A team of experts—endocrinologists, surgeons, oncologists, radiologists, and others—work together to decide on the best treatment plan. They help patients make decisions that match their health needs and personal values.
In summary, thyroid cancer is often slow-growing and curable, especially when found early. New guidelines encourage gentler treatments for low-risk cases, avoiding unnecessary surgery.
For advanced cancers, modern therapies like targeted and immune treatments offer hope. It’s important for patients to talk with a skilled team to find the treatment that works best for them.
