Thyroid cancer is a type of cancer that occurs in the thyroid gland, located in the front of your neck. It is more common in women than in men, and also affects people of all ages, races, and ethnicities.

The thyroid gland produces hormones that regulate metabolism and other bodily functions. When cancer cells are found in the thyroid gland, it can develop into thyroid cancer.

Causes and Risk Factors

The exact cause of thyroid cancer is unknown, but researchers have identified several risk factors that increase the chances of developing the disease. These include:.

Family history of thyroid cancer
Previous radiation therapy to the head and neck
Exposure to radiation fallout from nuclear disasters
Thyroid nodules or an enlarged thyroid gland
Being female

While some risk factors cannot be avoided, there are ways to reduce your risk of developing thyroid cancer. You can avoid excess radiation exposure, maintain a healthy weight, and eat a healthy diet that includes fruits, vegetables, and whole grains.

Symptoms of Thyroid Cancer

Thyroid cancer may not cause any symptoms or be discovered during a routine physical exam or imaging test. However, in some cases, symptoms may include:.

A lump or swelling in the neck
Hoarseness or difficulty speaking
Pain in the neck or throat
Difficulty swallowing
Enlargement of the lymph nodes in the neck

If you experience any of these symptoms, it is important to see your doctor right away. Your doctor will perform a physical exam and may order imaging tests, such as an ultrasound or CT scan, to determine if you have thyroid cancer.

Types of Thyroid Cancer

There are several types of thyroid cancer, including:.

Papillary thyroid cancer – This is the most common type of thyroid cancer and usually occurs in young women. It grows slowly and is typically very treatable.
Follicular thyroid cancer – This type of thyroid cancer is less common than papillary cancer and tends to occur in people over the age of 50. It is also treatable.
Medullary thyroid cancer – This type of thyroid cancer is less common than papillary and follicular cancer and can occur in families as a result of a genetic mutation.
Anaplastic thyroid cancer – This type of thyroid cancer is rare and grows very quickly. It is more difficult to treat and can be life-threatening.

Treatment Options

The treatment for thyroid cancer depends on the type and stage of the cancer, as well as the patient’s overall health. Treatment options may include:.

Surgery – This is the most common treatment for thyroid cancer and involves removing all or part of the thyroid gland.
Radiation therapy – This treatment uses high-energy X-rays to kill cancer cells and stop them from growing.
Chemotherapy – This treatment uses drugs to kill cancer cells throughout the body.
Targeted therapy – This treatment uses drugs to block specific molecules that are involved in cancer growth.

Your doctor will work with you to determine the best course of treatment for your specific type of thyroid cancer.

Survival Rates

The survival rates for thyroid cancer are generally good. The five-year survival rate for papillary thyroid cancer is nearly 100%, while the five-year survival rate for follicular thyroid cancer is around 85%.

The five-year survival rate for anaplastic thyroid cancer is less than 10%. However, survival rates can vary depending on the stage of the cancer and other factors, such as the patient’s age and overall health.

Conclusion

Thyroid cancer is a relatively common type of cancer that occurs in the thyroid gland. It is more common in women than in men and can affect people of all ages, races, and ethnicities.

While the exact cause of thyroid cancer is unknown, there are several known risk factors, including family history, exposure to radiation, and an enlarged thyroid gland. Symptoms may include a lump or swelling in the neck, difficulty speaking, and pain or difficulty swallowing. Treatment options include surgery, radiation therapy, chemotherapy, and targeted therapy.

The survival rates for thyroid cancer are generally good, but vary depending on the type and stage of the cancer.
