Radiation-induced thyroiditis is a form of painful, acute thyroiditis resulting from radioactive therapy to treat hyperthyroidism or from radiation to treat head and neck cancer or lymphoma. It affects 1% of those who have received radioactive iodine (I-131) therapy for Graves' Disease , typically presenting between 5 and 10 days after the ...
These cells are often found in the thyroid. The thyroid is a butterfly-shaped organ, responsible for producing various hormones for metabolism. These cells are often benign, but they can be malignant and metastasize. Hürthle cells are resistant to radiation, but can be treated using radioactive iodine treatment. [4]
Thyroid cancer accounts for less than 1% of cancer cases and deaths in the UK. Around 2,700 people were diagnosed with thyroid cancer in the UK in 2011, and around 370 people died from the disease in 2012. [70] However, in South Korea, thyroid cancer was the 5th most prevalent cancer, which accounted for 7.7% of new cancer cases in 2020. [71]
Thyroid neoplasm is a neoplasm or tumor of the thyroid. It can be a benign tumor such as thyroid adenoma, [1] or it can be a malignant neoplasm (thyroid cancer), such as papillary, follicular, medullary or anaplastic thyroid cancer. [2] Most patients are 25 to 65 years of age when first diagnosed; women are more affected than men.
The beta radiation released damages both normal thyroid tissue and any thyroid cancer that behaves like normal thyroid in taking up iodine, so providing the therapeutic effect, whilst most of the gamma radiation escapes the patient's body. [7] Most of the iodine not taken up by thyroid tissue is excreted through the kidneys into the urine.
Radioiodine therapy with iodine-131 can be used to shrink the thyroid gland (for instance, in the case of large goiters that cause symptoms but do not harbor cancer—after evaluation and biopsy of suspicious nodules has been done), or to destroy hyperactive thyroid cells (for example, in cases of thyroid cancer). The iodine uptake can be high ...
The body's need for thyroid hormone can also change over time, such as in the first months after radioactive iodine treatment (RAI). Thyroid autoimmune diseases can also be volatile [citation needed], as hyperthyroidism can interchange with hypothyroidism and euthyroidism. [2]
Papillary thyroid cancer (papillary thyroid carcinoma, [1] PTC) is the most common type of thyroid cancer, [2] representing 75 percent to 85 percent of all thyroid cancer cases. [1] It occurs more frequently in women and presents in the 20–55 year age group.
