  Thyroid cancer

The probable causes of thyroid cancer are not known. Doctors and scientists, however, observed that thyroid cancer affects more women than men. They do not full understand the reasons. Exposure to radiation during childhood is one of the risk factors. Those that were treated with radiation over their head and neck areas have a higher than average risk of developing thyroid cancer.

Thyroid cancer can be detected. It is recommended that anyone who received radiation therapy in childhood be examined regularly by a doctor every 2 years. Careful examination of the neck should be conducted, taking note for lumps and enlargement lymph nodes. Ultrasonography and scintogram may be recommended.

A lump, or nodule is the most common symptom of thyroid cancer. Pain is not a usual early warning for thyroid cancer. A full feeling in the neck, difficulty breathing and swallowing, hoarseness, or swollen lymph nodes can also be seen in some patients. However, these symptoms are not specifically caused by thyroid cancer. There may be some other, less serious problems. A doctor should be consulted once these symptoms are felt.

There are different types of thyroid cancer. Papillary cancer is the most common type of thyroid cancer, accounting for half of all thyroid cancers. The tumor appears as a small, firm, solitary mass with shaggy, gray cut surface. Hemorrhages and cysts are common. Microscopically, there are delicate papillary malformations consisting of fibrous connective tissue covered by columnar epithelium.

The epithelial cells are somewhat larger than normal, with abundant cytoplasm and small nuclei. Though anyone can have papillary carcinoma, it is most common in women. When the cancer is small, the prognosis is generally excellent, but for patients with very large tumors, it isn't as positive when it invaded other tissues. Follicular cancer is another type of thyroid cancer. It affects slightly older population. This type of cancer does not spread to lymph nodes but to arteries and veins rather. Medullary cancer develops in calcitonin-producing C cells. There are three types of medullary cancer -- sporadic, multiple endocrine neoplasia, and familial. Aplastic cancer is a rare thyroid cancer. It is aggressive and spreads rapidly t lymph nodes and to the other ograns. It is not curable surgically once diagnosed. Thyroid lymphoma is another rare type. Lymphomas usually start in the lymph nodes, but in some cases, they appear in thyroid.

DNA, the genetic material containing the detailed instruction for cells to divide in an orderly way, can be altered. These changes may lead to abnormal and out of control growth. This eventually form a tumor. DNA damage can occur due to radiation, the aging process and from genetic causes.

Although the cause of thyroid cancer is not known, there are risk factors that can contribute to its development. These are exposure to radiation, having a family history of familial medullary cancer, certain inherited conditions such as Gardner's syndrome or familial adenomatous polyposis, reproductive history of having last pregnancy at age 30 or more, and white American race.

Complications of thyroid cancer include difficulty swallowing and breathing when the cancer presses on your windpipe and esophagus. Hoarseness can also be a complication if the nerves controlling your vocal cords are irritated and damage. Diarrhea is caused by medullary thyroid cancer. Mestastasis is the most serious of all complications. This is most likely to happen in anaplastic cancer.

Surgical removal is the main treatment. For papillary and follicular cancers, the optimal treatment is near-total thyroidectomy. Affected lymph nodes may also be removed if there are enlarged lymph nodes. Another treatment for papillary and follicular cancers is radioactive iodine therapy. This is to destroy rims of tissue that have been left after surgery. It can also be used to destroy cancer that has spread beyond the thyroid gland.
