original weight. His muscles are wasting, and he is weak. He tries to move around the house throughout the day but tires easily. It has been difficult for him to access care, and he is just starting treatment for his cancer. 1. With continued exposure to the ionizing radiation, DNA damage occurred. What are the three stages of carcinogenesis that occurred after his exposure to radiation? 2. David is a healthy and active man, and his wife often remarked on how much food he used to eat for dinner after work. What would cause the muscle wasting and weight loss now? Explain your answer using what you have learned about the metabolic changes seen with cancer. 3. Muscle weakness may result from the production of onconeural antigens. A. Explain the effects of these antigens? B. In what form would this process likely take in David’s condition?

Question
David worked for a decade in a nuclear power plant. After fifteen years he has developed small cell lung cancer. David is anorexic and has lost a much of his original weight. His muscles are wasting, and he is weak. He tries to move around the house throughout the day but tires easily. It has been difficult for him to access care, and he is just starting treatment for his cancer.
