Microwaves are safe for cooking when used within recommended guidelines and do not alter DNA structure or pose a cancer risk. Modern microwave ovens have safety features that prevent radiation leakage and using microwave-safe containers minimizes chemical leaching. Microwaving retains nutrients better than prolonged cooking or boiling. To minimize risks, follow manufacturer's instructions, inspect the oven for damage, use microwave-safe containers, stand at a safe distance, and maintain a balanced diet. Stay informed through reputable sources.
