What is histopathology?- Histopathology is a process whereby a specially trained pathologist analyses tissue samples using a microscope to look for evidence of disease including cancer. Samples are taken by clinicians including general practitioners, physicians and surgeons, placed in a preservative fluid medium and are processed in the pathology laboratory to produce slides which are then examined by the pathologist. Pathology is regarded by many in the medical profession as the definitive test in the diagnosis of cancer.
What is cytology?- Cytopathology is similar to histopathology except the it relies on the examination of the appearances of individual cells to arrive at a diagnosis as compared with histopathology in which pieces of tissue are studied. Cytopathology is partly used as a screening tool in the diagnosis of breast and cervical cancer. However, cytopathology can also provide a definitive diagnosis in many cases and other additional tests such as immunohistochemistry and molecular analysis can be performed on certain samples.
