Biopsy Definition

Biopsy: A surgery that removes a tumor, or a sample of a tumor, for the purpose of cancer diagnosis. The specimen is submitted to a pathologist, where special processing and examination of the tissue yields a classification of the cancer (or lack thereof). Because of the time it takes to properly prepare and examine biopsies, the results are usually not available for at least five days, and often not for as long as ten days.
