The purpose of a biopsy is to remove and examine tissue for signs of disease. This medical procedure allows healthcare providers to obtain a sample of tissue, which is then analyzed microscopically to identify any abnormalities or disease processes, such as cancer, inflammation, or infection. By examining the cellular architecture and composition of the tissue, clinicians can make informed decisions regarding diagnosis and treatment options.
In this context, options discussing surgery, allergy testing, and blood pressure monitoring do not relate to the specific purpose of a biopsy. Surgery typically involves the treatment of a condition rather than sampling tissue. Testing for allergies assesses the body's immune response to allergens, while monitoring blood pressure evaluates cardiovascular health, neither of which involves direct tissue examination for diagnostic purposes. Thus, the primary function of a biopsy is to aid in the diagnosis of various medical conditions by analyzing tissue samples.
