I'm sorry for any confusion, but Rheumatology and Oncology are typically considered two separate branches of medicine. Rheumatology mainly deals with the diagnosis and therapy of rheumatic diseases, including autoimmune diseases, and musculoskeletal pain

I apologize for any confusion, but Rheumatology and Oncology are distinct medical fields. Rheumatology focuses on diagnosing and treating rheumatic diseases, such as arthritis and autoimmune disorders, which often cause joint and muscle pain. Oncology, on the other hand, specializes in diagnosing and treating cancer. While they are separate, some patients with rheumatic diseases may develop cancers and be referred to oncologists for specialized care. If you'd like, I can provide more information about each field separately and how they may occasionally intersect.
