Biopsy at Veterinarium - An Important Step Toward an Accurate Diagnosis

A biopsy is an important diagnostic method used to determine the nature of a mass. Specifically, it helps establish whether the lesion is malignant or benign. In addition, a biopsy allows for the evaluation of various tissue changes, including inflammatory processes, degenerative alterations, and other pathological conditions.

The biopsy procedure involves collecting a small tissue sample from the area of interest for subsequent histopathological examination.

At our clinic, the procedure is performed using the Magnum Core Needle Biopsy instrument, which allows us to obtain tissue samples measuring 15 mm or 20 mm in length. With the core needle biopsy technique, samples can be collected from the liver, kidneys, spleen, lymph nodes, prostate, urethra, mammary glands, subcutaneous masses, as well as other soft tissue lesions.

The procedure is conducted under ultrasound guidance, ensuring precise localization, improving diagnostic reliability, and minimizing the risk of potential complications.

Core needle biopsy is a safe and minimally invasive method. It does not require surgical intervention and is generally not associated with significant stress for the animal. In many cases, the procedure can be performed without sedation. When necessary, only short and light anesthesia is used.

Biopsy is often discussed in comparison with Fine Needle Aspiration (FNA). FNA involves collecting cellular material using a thin needle and is considered a quick, simple, and less invasive diagnostic technique. However, FNA provides only cytological evaluation, meaning that individual cells are assessed rather than the tissue architecture. Core needle biopsy, on the other hand, yields an intact tissue sample, allowing for histopathological analysis and often offering higher diagnostic accuracy, particularly in the evaluation of complex or suspicious lesions.
