Document Summary
The diagnostic toolkit: clinical findings: examination and family history, supported by laboratory findings, radiological (imaging) results, pathological findings: examination of tissue removed from the body (biopsy, blood work) Pathology: science of disease diagnosis through examination of organs, tissues, cells and body fluids, compares findings to what is considered normal due to changes in the tissue, knowing something is wrong, by knowing what is right. The example of hepatitis c disease: natural history. Cell and tissue morphology and biochemistry: diagnosis: identification of the disease, grade: degree of deviation from normal, stage: extent of disease. Staging cancer: size of the cancer = tumour size = t, whether or not the cancer has spread to other parts of the body beyond the primary site. Lymph node vs. no lymph node involvement = node involvement = n. = metastases = m: differentiated cells are mature, functional components of a tissue.
