Biopsy

Term: Biopsy

Definition: A biopsy is a medical procedure in which a small sample of tissue is removed from the body for examination under a microscope to diagnose diseases, including cancer and other abnormalities.

Phonetic Pronunciation: (BY-op-see)

Etymological Origin: The term "biopsy" is derived from the Greek words "bios," meaning life, and "opsis," meaning sight or view. It was first used in the late 19th century to describe the process of examining living tissue to diagnose disease.

Significance in Asbestos Context: Biopsies are crucial in diagnosing asbestos-related diseases, such as mesothelioma, lung cancer, and asbestosis. For example, a biopsy of lung tissue or pleural tissue can confirm the presence of asbestos fibers or asbestos-related malignancies. This procedure is often a key step in establishing a medical diagnosis, which is critical for both treatment planning and legal claims related to asbestos exposure.

Synonyms or Related Terms: Tissue sampling, histopathology, cytology (when referring to cell analysis).

Example Sentence: "The doctor performed a biopsy on the patient's lung tissue to confirm the diagnosis of mesothelioma caused by asbestos exposure."
