Are thyroid nodules always thyroid cancer? I have a thyroid nodule and my levels of some thyroid hormone are low. My doctor wants to do more tests, but I don’t really understand what he said. Do I have cancer, or could it be something else?
Over . Over 95% of thyroid nodules are benign. Therefore the risk of cancer is low, but can be increased in younger or older people, people with a family history of thyroid cancer, or people who have been exposed to radiation (x-rays do not count). Sometimes benign thyroid nodules can secrete extra thyroid hormone, more than your body needs. If your doctor is suspicious of this, they will order a nuclear study called a thyroid uptake and scan. If a nodule is over a centimeter, that is when we usually will perform a fine needle aspiration to get a sample of cells in the nodule. If nodules are under a centimeter and there is no evidence of over activity, we can simply monitor with serial ultrasounds.
No. There are many things that can cause this most of which are benign. Bloodworm and an ultrasound and rarely a small biopsy can answer specifically what your cause is. Most are benign in nature.
Not necessarily. A thyroid nodule just means a mass or growth. >70% of nodules are benign, even higher if you have multiple nodules. This is also age dependent (the older you are the less likely they are to be benign). The most common cancer is papillary carcinoma, and it usually shows up as a single nodule. Read more...
During a neck lymph node ultrasound, accidentialy a 3 mm hypoechoic thyroid nodule was found. Is it something to worry about now, should I get biopsy or check it regullary or leave it. I have a family history of thyroid cancer (father, 1st cousin)?
Your FAMILY HISTORY. alone makes this something that needs surgical evaluation (more tests could be done but I personally would want a BIOPSY and more likely than not an EXCISIONAL biopsy (take it out!!) Hope this helps! BTW you should be evaluated for possible thryroid hormone replacement as a way of avoiding future nodule formation! A Board Certified Endocrinologist is the way I would "go"! Z.
