Advances in animal research have contributed to treatments for which diseases?

• A. Polio, cancer, and diabetes
• B. Alzheimer's disease
• C. Only infectious diseases
• D. None of the above

Answer: (A)

Animal research acts as a vital bridge from basic biology to real medical treatments, allowing scientists to test ideas, safety, and effectiveness before they reach people. This work has touched a broad range of diseases, not just infectious ones. For example, in polio, animal studies helped establish safe vaccines and delivery methods that led to widespread protection. In cancer, animal models are used to develop and refine chemotherapy, targeted therapies, and immunotherapies, helping translate discoveries from the lab to patients. In diabetes, animal experiments contributed to understanding insulin and how to replace or regulate it in people who need it. Because its impact spans multiple disease areas, the option listing polio, cancer, and diabetes best captures the real breadth of animal research contributions.
