FNB Full Form in Medical term is Fine Needle Biopsy. With the use of a biopsy, suspicious tissue can be removed and studied under a microscope.
In addition to being examined under a microscope, a biopsy sample may undergo a variety of other procedures. Most forms of cancer are diagnosed through a biopsy. A fine needle biopsy is just one type of biopsy.
A fine needle biopsy involves the insertion of a thin, hollow needle into the questionable spot through the skin. A little sample of cells & sometimes fluid is drawn into the syringe connected to the needle.
A fine needle aspiration (FNA) is another name for this operation. It’s the most gentle of the biopsy techniques, thus it’s called minimally invasive.
Fine needle biopsy can be done during endoscopy or bronchoscopy. Endoscopy and bronchoscopy are both diagnostic procedures that allow doctors to see into a patient’s body and airways, respectively.
Your doctor or an outpatient clinic will likely do a fine needle biopsy. A radiologist can perform an image-guided biopsy in a medical facility such an imaging centre, hospital, or clinic.
A hospital gown may be required, depending on the site of the biopsy. The location will also dictate whether you should sit up, lie down, or switch positions. Be as still as possible throughout the operation.
