The collection of histopathological data involves several steps: 1. Biopsy/Surgical Removal: Specimens are obtained through biopsy or surgery. 2. Fixation: Tissue is preserved using fixatives (e.g., formalin) to prevent decay. 3. Processing: Tissues are dehydrated, cleared, and embedded in paraffin wax. 4. Sectioning: Thin sections of tissue are cut using a microtome and placed on slides. 5. Staining: Sections are stained with specific dyes (e.g., hematoxylin and eosin) to highlight different tissue components. 6. Microscopic Examination: Pathologists examine the prepared slides to identify any pathological changes.
