Thyroid cancer is the most common endocrine cancer. Thyroid cancer is a cancerous tumor or growth located within the thyroid gland.

Thyroid cancer is one of the few cancers that has increased in incidence rates over the past several years. There are expected to be 11% more new cases in 2007 than in 2006 in the United States.

The American Cancer Society estimates that there will be about 33,550 new cases of thyroid cancer in the U.S. in 2007. Of these new cases, about 25,480 will occur in women and about 8,070 will occur in men. About 1,530 people (880 women and 650 men) will die of thyroid cancer in 2007.

Many patients, especially in the early stages of thyroid cancer, do not experience symptoms. However, as the cancer develops, symptoms can include a lump or nodule in the front of the neck, hoarseness or difficulty speaking, swollen lymph nodes, difficulty swallowing or breathing, and pain in the throat or neck.

There are several types of thyroid cancer: papillary, follicular, medullary, anaplastic, and variants.
Papillary and follicular thyroid carcinomas are referred to as well-differentiated thyroid cancer and account for 80-90% of all thyroid cancers. Variants include tall cell, insular, columnar, and Hurthle cell. Their treatment and management are similar. If detected early, most papillary and follicular thyroid cancer can be treated successfully.
Medullary thyroid carcinoma (MTC) accounts for 5-10% of all thyroid cancers. Medullary cancer is easier to treat and control if found before it spreads to other parts of the body. There are two types of medullary thyroid cancer: sporadic and familial. Genetic testing (of the RET proto- oncogene should be performed in all patients with MTC to determine whether there are genetic changes that predict the development of MTC. In individuals with these genetic changes, removal of the thyroid during childhood has a high probability of being curative.
Anaplastic thyroid carcinoma is the least common and accounts for only 1-2% of all thyroid cancer. This type is difficult to control and treat because it is a very aggressive type of thyroid cancer. ...
