What does a core biopsy involve?

• A. Needle aspiration of fluid
• B. Removal of a larger needle core sample
• C. Diagnostic imaging only
• D. Excision of the entire breast

Answer: (B)

A core biopsy involves the removal of a larger needle core sample from a suspicious area in the breast tissue. This procedure is designed to gather enough tissue for examination to determine the presence of disease or abnormalities, such as cancer. During the core biopsy, a specially designed needle, often guided by imaging technology such as ultrasound or mammography, is used to extract a cylinder of tissue. This sample allows pathologists to conduct a more conclusive analysis compared to other methods, such as fine needle aspiration, which collects smaller amounts of material.

This method is particularly valuable for obtaining a larger volume of tissue for diagnosis, as it preserves the architecture of the cells and provides more accurate information on the nature of any potential disease. Hence, choice B accurately describes the essential procedure involved in a core biopsy.
