Onconephrology is a field of medicine that deals with the study and treatment of kidney diseases related to cancer. This term can be shortened to "renal oncology" or "cancer-related kidney diseases". Other synonyms for onconephrology include "nephro-oncology" and "renal neoplasms". These terms are often used interchangeably to describe the intersection between kidney and cancer-related diseases. Onconephrology has become increasingly important as the incidence of kidney cancer has risen globally. It is a relatively new field that combines both nephrology and oncology. Doctors and researchers in onconephrology work towards better understanding and treating cancer-related kidney diseases, improving patient outcomes and quality of life.
