Once the tissue sample is obtained, it is sent to a histology lab where it undergoes several steps:
Fixation: The tissue is preserved using chemicals such as formalin to prevent degradation. Embedding: The tissue is embedded in a solid medium, usually paraffin, to provide support during sectioning. Sectioning: Thin slices of the tissue are cut using a microtome. Staining: The tissue sections are stained with dyes to highlight different cellular components.
After these steps, the slides are examined under a microscope by a histologist.
