How Accurate Is A Fine Neddle Biospy On The Thyroid
Good--but limited: Fna is an excellent technique for papillary, medullary and undifferentiated cancer. However, there are limitations for a follicular tumor or nodule. You need to look at the periphery of a nodule to see if there is invasion before you can accurately classify these lesions. So, if you have a single nodule, fna is a good screening tool, but it cannot absolutely access all types of thyroid conditions. ...Read moreSee 2 more doctor answers
Biopsy is tissue removed by needle or cutting to remove part of a body part. It is usually a small amount of material that is processed by a pathologist. Most of the time it is stained and looked at through a microscope to arrive at a diagnosis. Special processes are done for some tissues or problems. The purpose is to tell what the problem is (diagnosis). ...Read more
Is it possible to have enlarged lymph nodes with hoshimotos hyper thyroidism ? And why they need a biopsy ?
Should biopsy be done on less than 1cm thyroid nodules with irregular borders? Why? Will it be accurate?
Depends: This depends on many factors - the presence of other signs (microcalcifications), the rate of growth, history of thyroid cancer in your family, the presence of thyroiditis, and the skill of th person doing the biopsy (should only be done with the use of an ultrasound as its probably too small to palpate). But generally if its amenable to biopsy i would recommend it. Can also recheck it in 3-6 mo. ...Read moreSee 1 more doctor answer
Screening test: A fine needle aspirate is usually done if there is a nodule in the gland. It provides a limited sample but can be diagnostic depending on the cause of the nodule. It may show just fluid, if the nodule is a cyst to showing cancer cells if the nodule is cancer. A negative test does not rule out disease due to limited sampling. ...Read more
This is how I do it: After local anesthesia is given (an injection just under the skin), a very fine needle is guided into the thyroid nodule through ultrasound visualization. I repeat the needle pass 4 times. Each pass only lasts for a few seconds. It is very well tolerated and it takes 20 minutes or so in all. There are no special precautions after the biopsy, other than wearing a band-aid for 2-3 hours. ...Read moreSee 1 more doctor answer
Thyroid FNA: Assuming the fna sample was adequate and representative of the lesion, a diagnosis of a benign nodule means that it is very likely that your thyroid nodule is not cancerous. It should still be periodically evaluated by your doctor, just to make sure that there are no significant changes. ...Read moreSee 1 more doctor answer
What should I expect with a fine needle biopsy of my thyroid? What are the possible tumors or results?
Well tolerated: Many times we biopsy nodules seen on ultrasound. Most are benign. If a cancer is seen, most of the time it is papillary, and treatable with thyroidectomy and lymph node removal. There can be follicular cells seen, which usually results in removal of one side of the thyroid, as you can't tell for sure if its noncancerous follicular cells on fna. Rarely, they dont get enough cells to tell. ...Read more
I DO!!!: I have performed many thyroid fine-needle biopsies and have had more than a few biopsies of my own thyroid. To be honest, it hurt more than i expected when i had my first biopsy because i didn't anticipate that the thyroid has pain fibers (it does). However, the pain is very short-lasting and, as a typical low-pain threshold man/doctor, if i can handle it... ...Read moreSee 2 more doctor answers
