Needle Biopsy (Overview)

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 contain cells for evaluation.

Is the recovery time after needle biopsy long?

Is the recovery time after needle biopsy long?

Typically not: The risks of complications does however depend on what is being biopsied.

Needle biopsy? How does a needle biopsy work? Why would some one get a needle biopsy?

Needle biopsy? How does a needle biopsy work? Why would some one get a needle biopsy?

Needle Biopsy.: Large bor needle is inserted into the object of interest then removed with a piece of tissue remaining inside the needle. A needle biopsy is cheaper, faster, generally safer and sometimes the only alternative to major surgery. In medicine we always try to do the least invasive and dangerous test first.

I have a tiny hole where the needle biopsy was performed. It's been months but the hole hasn't healed. It's really a tiny hole, its quiet strange.?

It'll stay: Scar contracts and this is why you will have this little mark. This is common and depending on the site can be the norm. At surgery or autopsy, old biopsy sites can often be identified. It this truly bothers you and your friends, you can ask a plastic surgeon or dermatologist about a filler. I suspect instead that you're simply curious about healing -- that's a good thing. Cheers.

Is a lapriscopy biopsy usually more accurate than a needle biopsy?

Sometimes: It depends on what is being biopsied and the amount of tissue sent for evaluation.

Is it more painful to have a core needle biopsy of three different spots than only one? What about the recovery? It takes more time?

Is it more painful to have a core needle biopsy of three different spots than only one? What about the recovery? It takes more time?

Biopsy: Logically you may expect more discomfort from 3 pokes than from a single one. But nowdays biopsies are done under some anesthesia, so there is a good chance amount of pain will be minimal either way. Recovery is usually minimal, however, it depends on what organ is biopsied. I wish it goes well for you and nothing bad is found.

How accurate is a fine needle biopsy?

How accurate is a fine needle biopsy?

Very Accurate: An article from baylor in 2000 looked at more than 6000 patients who underwent thyroid fna biopsy. Sensitivity and specificity values of thyroid fna were 93% and 96%. The current nci classification: 1) nondiagnostic fna samples, 2) benign lesions, 3) malignant lesions, 4 atypia/follicular lesion of undetermined significance, 5) suspicious for a follicular lesion. Most common result benign.

What does a fine needle biopsy feel like?

A pin prick: Most fnaers numb the area on the skin above a thyroid nodule with xylocaine (lidocaine) using a very fine grade needle so that the larger needle will not be felt.

What is a needle biopsy of a lymph node like?

What is a needle biopsy of a lymph node like?

Simple: A fine needle aspiration biopsy means using a thin needle (like the ones used to draw blood) to draw a very small tissue or cell sample from the lymph node. The sample is examined under microscope by a pathologist who can often make a diagnosis without the need for a surgical procedure to remove an entire node

What should I expect with a fine needle biopsy?

What should I expect with a fine needle biopsy?

Benign or malignant: An fna of a thyroid nodule can tell with great accuracy whether the nodule is cancerous and what type of cancer it is.

What should I bring for a prostate needle biopsy?

What should I bring for a prostate needle biopsy?

Unclear question: Ursula! Must presume you are going to your partner's or friends prostatic biopsy. Unless you have undergone gender change. If so, just take yourself and you will be given antibiotics and a prescription for pain meds.

Is the prostate needle biopsy a risky thing to do?

Little: Prostate biopsy is done transrectally--meaning going through the tissue in your rectum/anus area and carries a very small risk of infection and bleeding. It is certainly not fun, but overall it is considered a pretty safe procedure, done routinely in the doctor's (urologist office)...

Is a laparoscopy biopsy more accurate than a needle biopsy?

Is a laparoscopy biopsy more accurate than a needle biopsy?

Apples N' Oranges: A biopsy is usually performed for tissue diagnosis of a tumor. The best method of biopsy (bx) is the safest, least invasive means to reach this dx. Therefore, the specific technique is based on what is being bx'd & where it's located. In the abdomen, most tumors can be bx'd by (ct or ultrasound-guided) needle bx. Rarely, laparoscopy may be necessary if tumor cannot be seen radiologically.

Is local anesthesia enough to handle the pain of a core needle biopsy?

Is local anesthesia enough to handle the pain of a core needle biopsy?

Yes: During this procedure local anesthesia is injected exactly where the procedure is performed and can be performed without pain.

How much time does it take to receive results from fine needle biopsy?

1-2 days, typically: This answer is dependent on the kind of needle biopsy being performed. For instance, if it is a needle biopsy yielding cores of tissue (histology), then it usually takes 1-2 working days to get a final diagnosis. If it is a fine needle aspiration biopsy yielding fluid (cytology), the turnaround time may be shorter since fewer steps are necessary to prepare slides for microscopic examination.

How long after a needle biopsy until psa levels settle back to"normal" if you need another psa test? Thanks JC

PSA: Generally we wait at least 3 months after a biopsy before checking a PSA. If you check it any sooner you might see a falsely elevated PSA as a result of the biopsy. Some feel 4 to 6 weeks is adequate. I always wait 3 months

Do pathologists look at all tissue taken from a core needle biopsy? Are samples ever considered unusable if too small, etc?

All tissue examined: In the case of biopsies all tissues are examined. Even small pieces of tissue are important and are not ignored.

I have a complex 2cm complex nodule. Had needle biopsy and was blood filled. Could not diagnose it. Will follow up later. Should do anything else now?

Please ask again: E, you did not say where this nodule is or whether it is symptomatic (causing any problems). Please ask again providing these details. And of course, ask the doctor who discovered the nodule, and the one who did the biopsy, what you should do until "later". Good luck!

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
