Histopathology

Histopathology refers to the microscopic examination of tissues and cells. It is likely performed by examining cells and tissues under a light microscope or electron microscope, which has been sectioned, stained on a microscope slide, since accurate diagnosis of cancer and other diseases usually requires histopathological examination of samples. Histopathological examination of tissues starts with surgery, biopsy, or autopsy. The tissue is removed from the body of an organism and then placed in a fixative that stabilizes the tissues to prevent decay. The most common fixative is formalin, although frozen section of fixing is also common. Histochemistry refers to the science of using chemical reactions between laboratory chemicals and components within tissue
