The process begins with the collection of a tissue sample, often through a procedure called a biopsy. Once the tissue is obtained, it is fixed in a preservative solution, typically formalin, to prevent degradation. The sample is then embedded in paraffin wax and sliced into thin sections using a microtome. These sections are placed on slides and stained using various histological stains, such as Hematoxylin and Eosin (H&E), to highlight different cellular components. Finally, the slides are examined under a microscope by a pathologist.
