Thus, while FNA is beneficial for its ease and efficiency, it may not always provide conclusive pathology reports, necessitating follow-up procedures in some cases.
Core Needle Biopsy
Core needle biopsy (CNB) is somewhat of an evolution from the fine needle aspiration method. It uses a larger needle to extract thicker tissue samples, allowing for better histological evaluation of the breast. This technique is popular in current practices due to its higher accuracy in diagnosing malignancies. A distinctive feature of core needle biopsy is its ability to retain tissue architecture, which is critical for pathologists to assess cellular arrangements effectively. On the downside, the procedure can be a bit more uncomfortable for patients and carries a slightly higher risk of complications compared to FNA. Nevertheless, its diagnostic precision makes it a preferred choice in many instances, particularly when imaging suggests a malignancy.
Excisional Biopsy
An excisional biopsy involves surgical removal of a lump or a portion of breast tissue for comprehensive examination. This method is the most invasive among the three discussed, yet it offers the most definitive answers, often resolving uncertainties that less invasive biopsies cannot. One of the standout features of excisional biopsy is that it not only allows for diagnosis but can also be therapeutic, removing the lesion entirely. Despite its benefits, the procedure requires a longer recovery time and carries risks associated with surgical interventions, such as infection or scarring. This makes it less desirable for initial assessments unless there are compelling clinical reasons for opting for a more invasive diagnostic route.
