Your FNA specialist uses one of two ways to look at tissue samples to help determine if your lump is benign or malignant. FNA stands for fine needle aspiration. FNB stands for a fine needle biopsy. They do both work for collecting tissue samples. However, many people prefer FNA for lumps in their necks, faces, and heads. We’re going to break down the differences between the two in this post. Our goal is to give you all of the information that you need to make an informed decision.
Difference Between FNA and FNB
As we mentioned earlier, FNA is a form of biopsy using a
fine needle. FNB is also a biopsy method that involves using a needle. Your biopsy doctor LA
will use an ultrasound machine to look at the lumps and guide the needle into
the lump to collect cells. However, this is where the main difference comes
A sample taken using fine needle aspiration will show the
tissue samples on a cellular level. A sample taken using a fine needle biopsy
shows the tissue samples as an intact core. However, this doesn’t improve the
accuracy level over a tissue sample taken with FNA.
Both procedures are relatively quick. They can last anywhere
between 20 minutes and an hour from start to finish. You usually don’t do much
in preparation for either procedure. Your FNA specialist may recommend that you
discontinue taking certain medications 24 to 48 hours before you have the
procedure. You’ll also have minimal downtime after the procedure. Since this
procedure is very minimally invasive, you shouldn’t have a lot of pain after
the biopsy with either FNA or FNB.
Why Use FNA or FNB
For Neck and Head Masses
People like to use FNA or FNB to help diagnose neck or oral
lumps because there is a decreased risk of getting an infection during and
after the procedure. Since they use small and thin needles to extract the
samples, you won’t have to worry as much because you’ll end up with a small
needle hole instead of an incision.
There is also no anesthesia with fine needle aspiration or
with a fine needle biopsy. You will most likely get a local numbing agent
instead. In turn, you’ll have reduced surgical risks. Finally, people also
choose these types of biopsy methods because you can get precision results over
what you’d get with an incisional biopsy.
Both FNA and FNB are options for anyone who has a lump that
they want to find out if it’s benign or malignant. You should contact a biopsy doctor LA
to help understand your options. This is also an excellent time to set up an
appointment or a consultation.
