Modern pathomorphology is a key medical field, and treating neoplastic diseases would hardly be possible without it. It has an impact not only on saving patients, but also affects their quality of life. A pathomorphology report provides a formal basis for initiating oncological treatment, as it contains the information necessary to plan a therapy that is both safe and effective for the individual patient. To make this possible, a pathomorphologist needs access to the complete medical data, oncological history and type of treatment the patient received previously. Unfortunately, quite often the data pathologists receive is incomplete, which prolongs the tests and increases their cost. Therefore, adequate communication between pathologists and clinicians is necessary, as well as standard procedures for each step in the processing of tissue or cytology samples collected for pathomorphological testing.
