Does It Hurt To Have A Thyroid Needle Biopsy Done
A needle biopsy (or fine needle aspiration) is a procedure whereby a thin needle (similar to one the is used for drawing blood), is guided into a lesion and cells are obtained and then placed immediately onto a glass slide for evaluation under the microscope. Unlike a biopsy where "chunks" of tissue are obtained, a fna often obtains only several drops of fluid that ...Read more
Minimal discomfort: A fine needle aspiration biopsy of the thyroid is done with a fine gauge needle (usually 22 to 25 gauge). For comparison, when blood is drawn one usually uses an 18 gauge needle (lower gauge means larger needle). Usually local anesthesia is used so there should be very little discomfort. The actual biopsy only takes a few seconds for each needle pass (typically 4 passes are done). ...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
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
Thyroid Nodules 3.6 left 3.4 right Is a needle biopsy practical at this size? Should we just schedule removal of the thyroid.
Big nodules: Hi. Those are big nodules. They should only have FNAB done if you plan to NOT remove them if they're benign. If they're bugging you and you want them out even if they're benign, then you can skip FNAB. ...Read more
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
