Fine-needle aspiration. Fine-needle aspiration (FNA) is a percutaneous ("through the skin") procedure that uses a fine needle and a syringe to sample fluid from a breast cyst or remove clusters of cells from a solid mass. [6] It is mainly used to differentiate between a cyst and a mass. [6]
Breast cysts may remain stable for many years or may resolve spontaneously. [8] Most simple cysts are benign and do not require any treatment or further diagnostic workup. Some complex cysts may require further diagnostic measures such as fine needle aspiration or biopsy to exclude breast cancer however the overwhelming majority is of benign ...
Also, fine-needle aspiration is the main method used for chorionic villus sampling, [3] as well as for many types of body fluid sampling. It is also used for ultrasound-guided aspiration of breast abscess , [ 4 ] of breast cysts , and of seromas .
Pancreatic cysts Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of cystic lesions, followed by liquid cell analysis, has been used as a diagnostic tool for differentiating benign, potentially malignant, and malignant pancreatic cysts.
Breast cancer makes up about 10% of breast masses. [1] Diagnosis is typically by examination, medical imaging, and tissue biopsy. [2] Tissue biopsy is often by fine needle aspiration biopsy. [3] Repeated examination may be required. [2] Treatment depends on the underlying cause. [1] It may vary from simple pain medication to surgical removal. [1]
A stereotactic biopsy may be used, with x-ray guidance, for performing a fine needle aspiration for cytology and needle core biopsy to evaluate a breast lesion. However, that type of biopsy is also sometimes performed without any imaging guidance, [2] and typically, stereotactic guidance is used for core biopsies or vacuum-assisted mammotomy. [3]
A fine needle aspirate can be done with simply a small bore needle and a small syringe (1 cc) that can generate rapid changes in suction pressure. Fine needle aspirate can be used to distinguish a cystic lesion from a lipoma. Both the surgeon and the pathologist must be familiar with the method of procuring, fixing, and reading of the slide.
This is an exclusion diagnosis, mostly done based on the clinical presentation after ruling out breast cancer. Nipple fluid aspiration can be used as a classification cyst type method (and to some extent improve breast cancer risk prediction) but is rarely used in practice. Biopsy or fine-needle aspiration are rarely warranted. [12]
