Thyroid Cancer Does Not Absorb Iodine

Thyroid cancer is a type of cancer that starts in the thyroid gland. The thyroid gland is a small, butterfly-shaped gland located in the front of the neck. It produces hormones that regulate metabolism.

Most thyroid cancers are curable, but some types can be more aggressive. Treatment for thyroid cancer typically involves surgery to remove the thyroid gland, followed by radioactive iodine therapy.

Radioactive iodine therapy is a type of treatment that uses radioactive iodine to kill thyroid cancer cells. Radioactive iodine is a form of iodine that has been treated with radiation. When radioactive iodine is taken by mouth, it travels through the bloodstream to the thyroid gland. The thyroid gland absorbs the radioactive iodine and uses it to make thyroid hormones. The radiation from the radioactive iodine kills the thyroid cancer cells.

However, some types of thyroid cancer do not absorb iodine. These types of cancer are called "iodine-refractory" thyroid cancers.

Iodine-refractory thyroid cancers are more difficult to treat than iodine-avid thyroid cancers. This is because radioactive iodine therapy cannot be used to kill the cancer cells.

Treatment for iodine-refractory thyroid cancers typically involves surgery to remove the thyroid gland, followed by other types of treatment, such as chemotherapy or targeted therapy.

Symptoms of Thyroid Cancer

The symptoms of thyroid cancer can vary depending on the type of cancer. However, some common symptoms include:

A lump or swelling in the neck

Difficulty swallowing

Hoarseness

A change in voice

Pain in the neck

Swollen lymph nodes in the neck

Causes of Thyroid Cancer

The exact cause of thyroid cancer is unknown. However, some risk factors for thyroid cancer include:

A family history of thyroid cancer

Exposure to radiation

Certain genetic mutations

Diagnosis of Thyroid Cancer

Thyroid cancer is typically diagnosed with a combination of tests, including:

A physical exam

A blood test

A thyroid scan

A biopsy

Treatment for Thyroid Cancer

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

Surgery to remove the thyroid gland

Radioactive iodine therapy to kill thyroid cancer cells

Chemotherapy to kill cancer cells

Targeted therapy to block the growth of cancer cells

Prognosis for Thyroid Cancer

The prognosis for thyroid cancer is generally good. Most thyroid cancers are curable, and the majority of patients who are treated for thyroid cancer can expect to live a long and healthy life.

However, the prognosis for iodine-refractory thyroid cancers is less favorable. These cancers are more difficult to treat, and the survival rate is lower.

Prevention of Thyroid Cancer

There is no sure way to prevent thyroid cancer. However, some things that may help to reduce the risk of thyroid cancer include:

Avoiding exposure to radiation

Getting enough iodine in the diet

Maintaining a healthy weight

Exercising regularly
