Histological analysis involves several steps. First, a biopsy is performed to extract a tissue sample from the patient. This sample is then fixed, usually in formalin, to preserve its structure. Next, the tissue is embedded in paraffin wax and sliced into thin sections using a microtome. These sections are mounted on slides and stained with dyes, such as Hematoxylin and Eosin (H&E), to highlight different cellular components.
