Which field focuses on cancer care?

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

Answer: (D)

Oncology is the field focused on cancer care. It covers diagnosing and treating cancers, planning multidisciplinary care, and managing long-term outcomes. Treatments span medical oncology (drugs like chemotherapy and targeted therapies), surgical oncology (removing tumors), and radiation oncology (using radiation to destroy cancer cells), addressing cancers anywhere in the body. The other specialties focus on different areas—cardiology is about the heart, dermatology about the skin, and hematology deals with blood disorders (and includes some blood cancers, but not the broad specialty for all cancers).
