Pathologists are physicians who specialize in the diagnosis and characterization of disease based on the examination of tissues removed from diseased body parts or biopsy samples. Pathologist go through laboratory analysis of various bodily fluids such as the blood, semen, saliva, cervical fluid, pleural fluid (around the lungs), pericardial fluid (around the heart) and ascetic fluid (collected in the abdomen in liver disease).
Pathologists specialize in a wide range of diseases. Tissue samples are observed under a microscope and the cellular pattern observed to help determine if a sample is cancerous or non-cancerous (benign). Pathologists works in conjunction with clinicians to help them make decisions regarding the most appropriate treatments for different disease conditions.
