Pathologists Without Borders (PWB) is a Ghanaian medical diagnostics company that provides anatomical pathology services. Anatomic pathology is the branch of laboratory medicine that deals with diagnosis of diseases using tissues and cells. Tissues and cells are obtainable from the organs of sick people. Anatomic pathology diagnoses form the backbone of clinical diagnoses, management and follow up of patients. A patient suspected of having cancer must have a diagnosis of cancer from a pathology laboratory. This diagnosis is based on microscopic examination of tissues or occasionally cells taken from the organ suspected to be cancerous.
