diagnosis of thyroid cancer

Thyroid cancer is a disease in which the thyroid cells become abnormal, grow uncontrollably, and form tumors. A woman's risk of developing thyroid cancer is three times greater than a man's. Most people who develop thyroid cancer are 50 years of age or older, but the disease can affect teenagers and young adults.

The doctor may use several tests to confirm a diagnosis of thyroid cancer. The size and location of the lump has to be identified and it has to be determined whether the lump is non-cancerous called benign or cancerous known as malignant. The most accurate diagnostic tool for thyroid cancer is a biopsy. In this process, a sample of thyroid tissue is withdrawn and examined under a microscope.

A radioactive scan can be used to identify any abnormal areas in the thyroid. The patient is given a very small amount of radioactive iodine, which can either be taken by mouth or injected into the thyroid.

Having hypothyroidism symptoms is related to hormone imbalance and it is the simplest of the three types of thyroid disorders to treat. The current method of treatment for hypothyroidism is some form of daily thyroid hormone replacement. Other treatment such as radioactive iodine, antithyroid drugs and surgery are all effective treatments for hyperthyroidism
