= Pathologist
A <pathologist> studies and interprets changes in cells, <tissues> and <organs> associated with <disease>. In clinical work, this can involve examination of a <biopsy>, surgical specimen or body fluid alongside molecular and clinical information. Microscopic organization and molecular test results provide complementary evidence rather than interchangeable measurements. <Pathologist in the NCI Dictionary of Cancer Terms>[Definition: diagnosis through examination of cells and tissues]{ref}
For example, recognizing an abnormal <tissue> pattern answers a different question from identifying a particular genetic alteration in the same specimen. Relating both findings to the location and course of disease can refine a diagnosis. The role combines biological mechanism with careful control of specimen identity, sampling and interpretation.
