Which of the following is not a cancer-related term?

• A. Carcinogenesis
• B. Oncogenesis
• C. Tumorigenesis
• D. Biocompatibility

Answer: (D)

Cancer development terms describe how cancer forms and grows, while biocompatibility focuses on how a material interacts with living tissue. Carcinogenesis refers to the initiation and progression of cancer due to genetic changes and environmental factors. Oncogenesis is the process of tumor formation and malignant transformation. Tumorigenesis covers the development and growth of tumors from normal cells. Biocompatibility, on the other hand, deals with the safety and tissue response to a material used in the body, including aspects like cytotoxicity and irritation, not cancer pathways. Because biocompatibility does not describe cancer formation or progression, it is not a cancer-related term.
