Histopathology is a morphological science in which the shape and pattern of cells and tissues is examined in order to establish the presence or absence of disease, especially cancer.

histologyHistopathology is a morphological science in which the shape and pattern of cells and tissues is examined in order to establish the presence or absence of disease, especially cancer. The medical scientist is involved in the preparation of tissues for examination using either light or electron microscopy or computerised image analysis. A sample is usually obtained by removal of abnormal tissue during a surgical procedure (biopsy). This is then processed to allow very thin sections of tissue to be cut, mounted on slides and stained with dyes in order to visualise tissue structures. Alternatively, a sample may originate from an autopsy, in which case the results can be valuable in establishing the cause of death.
