What is a cold thyroid knot?

The chips are a gland located in the throat and the thyroid knot is the lump that develops in it. Thyroid knots are rarely cancer and are common, about half of all people aged 50 are likely to have at least one. Since there are many different types of thyroid nodes, the investigation is performed when it is found. Thyroid scans can show that the knot is hot, warm or cold. The hot knot produces excessive amounts of thyroid hormone, a warm knot creates a normal amount, while the cold thyroid produces small or none. When part of the thyroid gland is enlarged to form a hot node, the cells inside the node form too many hormones. Sometimes the enlargement can be components of the gland efforts to produce more hormone, as the gland is generally failing and the hormone level produced by each cell is too low. This can lead to the formation of a warm or cold thyroid node.

thyroid cancer is most often developed in the form of a lone node. Cold thyroid hasa higher chance of malignant or cancer than a warm or hot knot. Nevertheless, it has been found that approximately 95 percent of individual nodes are benign or non -lawyer in investigation. In addition to creating thyroids, nodes can consist of cysts, benign tumors or inflamed thyroid tissues.

The aim of the investigation is to provide information about the node and find out if it is cancer. Thyroid display scan includes the use of radioactive iodine. Because the thyroid gland uses iodine to produce its hormone, the more active gland, the more radioactive iodine will be accepted, and this can be evaluated on the X -ray. Depending on the amount of radioactive iodine represented on the X -ray, the lump can be classified as a hot, warm or cold thyroid knot. The only way to cz be sure that the cancer is present, should take a sample of lumps or is called a biopsy of thyroid knots.

Biopsy of the node withThey usually perform a technique called fine aspirations, where cells are pulled out of the lump using a needle and syringes. The cells are then examined under the microscope. Ultrasonic scanning can be used to guide the needle location. It may be possible to leave the nodes themselves that have been found to be benign and do not grow or cause symptoms. If cancer is discovered, regardless of whether the tumor is a hot, warm or cold thyroid knot, surgical removal of all or thyroid parts is usually required.
