Which procedure involves removing tissue for examination?

The correct answer is a procedure that involves the removal of tissue from a living body to examine it for diagnostic purposes. A biopsy is specifically designed to obtain a sample of tissue, which can then be analyzed under a microscope to identify the presence of disease, such as cancer. This examination allows for the determination of the presence, type, and severity of various medical conditions.

In contrast, an autopsy is performed post-mortem to determine the cause of death and is not applicable in a living context. Radiography refers to imaging techniques, such as X-rays, that visualize structures within the body rather than removing tissue for examination. Curettage involves scraping tissue from a surface, such as the uterus, but is not explicitly focused on the examination of a tissue sample in the same diagnostic capacity as a biopsy. Thus, a biopsy is uniquely positioned as the procedure aimed at obtaining tissue for examination.
