Defining Biopsy: Testing Diseased Organ Cells

The question asks for the term describing the process of removing and testing cells from diseased organs.

A Biopsy is a medical procedure where a sample of tissue or cells is taken from a diseased organ or body part and then examined in a laboratory. This process is crucial for diagnosis, determining the nature of the disease (like cancer), and guiding treatment.

Let's analyze the other options:

• Autopsy: This is a post-mortem examination of a dead body to determine the cause of death. It does not involve testing cells from living, diseased organs.
• Operation: This is a general term for any surgical procedure. While a biopsy is a type of operation, 'operation' itself is too broad and doesn't specifically describe the removal and testing of cells for diagnostic purposes.
• Amputation: This involves the surgical removal of a limb or a diseased part of the body. While tissue is removed, the primary definition focuses on the removal of the part itself, not necessarily the detailed cell testing inherent in a biopsy.

Therefore, Biopsy is the most accurate and specific term for the described process.
