Autopsy vs. Biopsy: What's the Difference?
Edited by Aimie Carlson || By Janet White || Updated on October 8, 2023
Autopsy is a post-mortem examination of a body; Biopsy involves removing tissue from a living person for diagnosis.
Key Differences
Autopsy and Biopsy are both medical procedures, but their purposes, contexts, and methods vary considerably. An Autopsy is a comprehensive examination conducted on a deceased individual's body. This examination is performed to determine the cause of death or to study disease processes. In contrast, a Biopsy involves the extraction of tissue or cells from a living person to identify the presence, cause, or extent of a disease.
While Autopsy is typically performed by a forensic pathologist or an anatomical pathologist, the procedure of Biopsy can be carried out by doctors across various specialties, depending on where the tissue is taken from. For instance, a dermatologist might perform a skin Biopsy, whereas a gastroenterologist could conduct a liver Biopsy. Autopsy, on the other hand, generally encompasses an examination of the entire body or specific organs.
It's crucial to note that Autopsies are post-mortem, meaning they occur after death. Biopsies, however, are predominantly diagnostic tools, used to confirm or rule out conditions, often malignancies. A patient undergoing a Biopsy is typically awaiting results to determine a treatment path, whereas an Autopsy seeks answers posthumously.
Lastly, the emotional and ethical contexts surrounding Autopsy and Biopsy can differ. Families might request an Autopsy to gain closure or clarity on a loved one's passing. Biopsies are often procedures accompanied by anxiety and hope, as patients and families await potentially life-altering results.
