APPLICATION / ANALYSIS

Q12. A tobacco user who has smoked for over 20 years is diagnosed with lung cancer, while a lifelong non-smoker in the same family shows no such symptoms. Using your understanding of carcinogens, explain the possible biological connection between long-term tobacco use and the development of cancer.

Q13. A doctor recommends a combination of surgery followed by chemotherapy for a patient whose cancer has already spread to nearby lymph nodes, rather than surgery alone. Explain, using your understanding of metastasis and cancer treatment, why a combined treatment approach might be necessary in this case.
