Thyroid gland cancer is caused when the thyroid cells becomes abnormal, form a cancerous tumor and grow uncontrollably.
It if is not treated properly, it can affect other parts by a process called metastasis. The thyroid gland cancer is four kinds. They are follicular, papillary, anplastic and medullary.
Papillary cancer is developed by the cells that contain iodine produced by the thyroid hormone. It grows slowly containing the cells that are same as healthy thyroid cells. It occurs at the rate of 60 to 80 percent of the thyroid cancer.
Follicular cancer is developed by thyroid cells and it can produce the iodine-containing hormones. This occurs at the rate of 10 to 30 percent.
Medullary thyroid cancer is difficult to control than follicular and papillary cancers. It is difficult as the cancer cells spread to other organs. Calcitonin is produced by the cells of medullary cancer. 5 to 7 % of the cancer is medullay cancer. Iodine does not contain in calcitonin.
The causes for the thyroid cancer are not known exactly. You can have certain factors that increase the risk of cancer.
Thyroid cancer develops due to certain factors:
- Family history with thyroid cancer
- Enlarged thyroid gland
- Exposure to radiation
- Due to the presence of nodules on the thyroid
- Thyroid Inflammation
- Chronic infections
Thyroid cancer has no certain symptoms in the early stages and it is a small lump. But, at later stages you can have the symptoms like difficulty in breathing, neck mass, neck pain, hoarseness, swollen gland and difficulty in swallowing.
It is very difficult to prevent this disease because most of the people with thyroid cancer do not have the risk factors.
The treatment of thyroid cancer depends upon the stage and kind of the disease and your health and age. The treatments generally used to treat this are:
- Radioactive iodine therapy or hormone therapy
Thyroid cancer statistics are as follows:
- About 1500 people in USA are diagnosed every year with thyroid cancer.
- In the United States, about 1200 people die due to the thyroid cancer every year.
- Women are mostly affected by this disease than that of men (about three times).
- People of Asian descent are more commonly affected with this disease.
Thus, you can know how the thyroid gland cancer is caused and treated.
