The thyroid gland is a small butterfly-shaped organ, about 10-20 grams, slightly below the middle of the neck (below the throat). A malignant form of cancer that causes a lump to form in a part of the thyroid gland is called thyroid cancer. Thyroid cancers are classified into several types according to their microscopic appearance, but most radiation-related thyroid cancers are of a type called papillary carcinoma.
