Biopsy (Definition)

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

I have a 5 CM thyroid nodule w/ blood flow, report says needs biopsy, what does this mean?

Needle biopsy : Nodules of that size can be biopsied using a technique called fine needle aspiration. The skin over the nodule is numbed with a local anesthetic. Then, usually with ultrasound guidance, a needle is passed through the skin into the nodule. A small sample is taken and then analyzed under a microscope. ...Read more

I'm 28 years old, had a thyroid nodule for 2 years. Finally got a biopsy. How likely is it to be cancer?

I'm 28 years old, had a thyroid nodule for 2 years. Finally got a biopsy. How likely is it to be cancer?

Likelihood: depends on size, whether it is solid, cystic, or complex, whether or not it is a "cold" nodule, and a lot of other things. Even if it is thyroid cancer, most of these are successfully treated with surgery with or without radiotherapy. ...Read more

Diagnosed with multiple thyroid nodules and going back to talk about options or biopsy. What options are there other than biopsy?

Diagnosed with multiple thyroid nodules and going back to talk about options or biopsy. What options are there other than biopsy?

Several options: Belfry: the fact that there are multiple nodules means that it is likely a benign multinodular goiter. Sometimes these are just watched with serial ultrasound exams as well as following your bloodwork. A biopsy is a fine needle aspiration and is minimally invasive. It is well-tolerated and you should do it if there is an atypical or dominant nodule that stands out from the rest. ...Read more

Need more data:: You might be hyperthyroid, but a low TSH would confirm this. Also, you need a free T3 & T4 done. If TSH low you need thyroid stimulating IgG. The measurements do not specify what was measured: total or free & T3 or T4. ...Read more

Complex thyroid nodule biopsied said to be benign... Now regardless of the diagnosis... Could it be possible that nodule is cancerous and biopsy missed it?

Complex thyroid nodule biopsied said to be benign... Now regardless of the diagnosis... Could it be possible that nodule is cancerous and biopsy missed it?

Possibly: Thyroid nodules are notoriously difficult to interpret biopsy results, because the nodules themselves are often "complex" meaning non-uniform, and thus one portion may look benign while the other malignant, . ...Read more

Thyroid nodule stable. What if I refuse a biopsy? Dont want cost or risk

Ok to refuse: If the thyroid nodule is stable like you said, there is no need for a repeat biopsy (unless the last one didn't get enough materials or if your doctor was concerned about something with the last biopsy). Discuss this thoroughly with your physician. As long as you continue to follow the nodule, you will be able to intervene sooner if something changes. ...Read more

Can a thyroid nodule biopsy results ever be wrong?

Can a thyroid nodule biopsy results ever be wrong?

Yes: In general, if a nodule is very large, there is a higher chance that it can be called benign although it still could be cancerous because not all of the nodule is typically cancerous. You could have one little speck of cancer that hide within the big mass and a biopsy could miss it because we can't "poke" you forever. However, if a biopsy came back "cancerous", it almost always is true. ...Read more

Does a solid 1.1 CM thyroid nodule need to be biopsy?

Does a solid 1.1 CM thyroid nodule need to be biopsy?

Yes: Solid nodules carry the risk of being thyroid cancer (although certainly most solid thyroid nodules are not cancer). Because of the risk, you should have a biopsy done (most can be done using a very thin needle while an ultrasound is being done). ...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

I have bilateral partially cystic thyroid nodules.Biopsy done of the larger one, came back "follicular lesion of unknown origin" what does that mean?

I have bilateral partially cystic thyroid nodules.Biopsy done of the larger one, came back "follicular lesion of unknown origin" what does that mean?

Variable meaning: Follicular?patterned lesions of the thyroid are common; these include hyperplastic/adenomatoid nodules, follicular adenoma, follicular carcinoma and follicular variants of papillary carcinoma. Repeat biopsy with a sample sent for a genetic afirma assay may give additional useful information. In addition, discuss with your endocrinologist. ...Read more

Is a thyroid nodule fna biopsy painful?

It varies: The level of discomfort experienced can vary considerably. Different people have different pain tolerance. Inflammatory nodules are likely to be more tender than cysts or tumors.

Can another fna thyroid nodule biopsy be taken 2 weeks after a previous fna biopsy?

Better to wait: Cytopathologists may preferr that you wait a couple of months if it is slightly suspicious but inconclusive. Inflammation can make interpretion harder. On the other hand, if the fna was nondiagnostic because of too few cells, it is desirable to repeat it within a reasonably short period of time. ...Read more
