What is often derived from a biopsy?

A biopsy is a medical procedure that involves the extraction of tissue samples from the body for examination. The primary purpose of conducting a biopsy is to determine the presence, cause, or extent of disease, particularly cancer. The tissue collected is then analyzed under a microscope by a pathologist, who looks for abnormal cells or other indicators of health issues. This analysis leads to a diagnosis, which is the identification of a disease based on the characteristics of the tissue.

The other options involve processes that happen after a diagnosis has been established. A treatment plan and medication prescription are determined based on the diagnosis. Likewise, a physical therapy schedule would be created in response to a specific diagnosis requiring rehabilitation. Therefore, the correct choice directly correlates with the fundamental goal of a biopsy, which is to provide a definitive diagnosis.
