Thyroid Nodules
It is highly possible for people to have benign thyroid nodules. In fact, the benign nodules are the most common. A lot of people can have a thyroid nodule at one time in their life. Most of the time nodules on thyroid do not cause any trouble. They merely are a result of the growth and function of the thyroid. Similar nodules are also very common in the adrenal glands, another portion of the endocrine system. Under the stimulation of other hormones, the thyroid can form nodules that are not cancerous and would not cause a person any trouble at any time in their life. But on a very small occasion, they can be serious and should be evaluated and taken out if necessary, sometimes with hypoechoic thyroid nodule surgery. This is rare, but always a possibility.
In the evaluation of nodules on thyroid, it is important to learn if the nodules are ‘cold’ or ‘hot’. This refers to whether or not the nodules are metabolically active and are secreting any thyroid hormone. Hot nodules create thyroid hormone and can cause problems with the entire body. A cold thyroid nodule does not secrete any substances and therefore have fewer problems than hot nodules. One of the reasons why the nodules are called ‘hot’ is because there are scans that are performed with radioactive isotopes that make the thyroid light up. If the nodule is active, it makes a hot spot in the scan and thus the nodule is called hot. If there is a cold thyroid nodule, it looks just like the rest of the tissue or does not show up at all, creating a cold hole in the scan.
If it is determined that the person needs surgery, there are several options that are available. In days past, everyone with thyroid nodules would have their entire thyroid removed. The idea was that if a thyroid is prone to creating one nodule, it may create more in the future. One of these nodules could become cancerous. Therefore it is better to be safe than sorry when it comes to thyroid surgery and take the entire organ out. The same was thought in breast surgery until modern techniques have shown that you only need to isolate the nodule and remove it.
One of the ways to effectively isolate a nodule is to use ultrasound to locate it. The nodules tend to have a a different density than surrounding tissue, and therefore do not produce as many echoes. Hence the name of the surgery is hypoechoic thyroid nodule surgery. The name tells the entire story. The nodule is found with the ultrasound because it is hypoechoic and then is operated upon with the specific methods to isolate the nodule from the surrounding tissue. This can be one of the best ways to treat problematic and benign thyroid nodules because it is the least invasive and the most accurate.
