Histopatolojiye, also known as histopathology, is the microscopic examination of biological tissues. It is a crucial tool in the diagnosis of diseases, particularly cancer. The process begins with a biopsy, where a small sample of tissue is removed from the body. This sample is then fixed, processed, and embedded in a solid medium, typically paraffin wax, to allow for thin slicing. These thin slices, called sections, are mounted on glass slides and stained with various dyes, such as hematoxylin and eosin (H&E), which highlight different cellular structures. A pathologist then examines these stained slides under a microscope.
The pathologist looks for abnormalities in cell shape, size, arrangement, and the presence of any invading or
