Nodules of the thyroid gland do not always cause symptoms that may indicate its presence. At times, discovered by chance. Then is the time to consider whether or not surgically removed. Let’s see what should be done in each particular case.
The discovery of a nodule
discovering one or more nodules in the thyroid depends on many circumstances. It may happen that someone will notice something strange in the neck and warns us of an alien presence. It may happen that the doctor is aware on a routine annual review.
We also realize that we nodules by ultrasound, when studying certain derangements in thyroid distance rates hormones in the blood. In some cases, the presence of nodules is manifested by pain, or because they get the trachea (breathing difficulties), or the recurrent laryngeal nerve (nerve of the word, which necessitates a change of voice).
One or more nodules
they may involve the presence of multiple nodules touching one of the two lobes of the gland or in its entirety. These nodules can be of different size and nature: liquids cysts or nodules “hot” or “cold.” They can also be benign or cancerous.
When the thyroid gland contains numerous nodules, it is said that there is a multinodular goiter. The best test that may allow the exact number of nodules, size and location is an ultrasound of the gland.
Hot or cold nodules
Hot or cold nature of a nodule is determined by its ability to bind iodine. If the nodule still highly radioactive iodine, say it is “hot.” In the opposite case we speak of “cold” nodule.
This distinction is important because hot nodules are often associated with strong secretion of hormones in the blood thyroid distance. These nodules are sometimes annoying because segregation of hormones is very strong and can have physiological effects. These hot nodules are rarely cancerous. However, most cold nodules are cancerous (10% of cases).
