What is the least expensive and least invasive method of breast biopsy?

The fine-needle biopsy (FNB) is the least expensive and least invasive method of breast biopsy due to its technique and equipment requirements. In FNB, a thin, hollow needle is inserted into the breast lump or suspicious area to extract a small sample of tissue. This approach typically involves minimal discomfort, no need for general anesthesia, and can often be performed in an outpatient setting, which helps keep costs lower compared to other biopsy methods.

Additionally, FNB does not require extensive preparation or recovery time, making it a convenient option for patients. It can be completed relatively quickly, enhancing its appeal as a first-line diagnostic procedure when breast abnormalities are detected. In many cases, FNB can provide sufficient information for diagnosis, allowing it to serve as an effective initial assessment without the need for more complex, invasive techniques.
