Onconephrology is a specialized field within nephrology that focuses on the intersection of cancer (oncology) and kidney-related health issues. This discipline addresses the complex relationship between cancer, cancer treatments, and kidney function. Patients with cancer often experience kidney problems either due to the cancer itself or as a result of treatments like chemotherapy, targeted therapy, and immunotherapy. Onconephrology aims to diagnose, manage, and prevent kidney-related complications in these patients.
