• A. Hematology
• B. Cardiology
• C. Dermatology
• D. Oncology

Answer: (D)

Onc ology is the field that focuses on cancer—the study, diagnosis, and treatment of malignant diseases. It covers how cancer develops, methods to detect and stage it, and the various treatments used to manage it, including surgery, chemotherapy, radiation therapy, and newer targeted or immune therapies, often delivered by a coordinated team of specialists. Hematology deals with blood conditions and disorders of the blood-forming system; cardiology is about the heart and its vessels; dermatology focuses on the skin. While there is overlap for blood cancers, the term oncology is the one specifically used for cancer care and management, making it the best choice.
