NS 1400 In-Class Test 3 Questions & Answers 2026/2027 | Cancer Biology, Lung Cancer, Epidemiology & Health Disparitie

This NS 1400 In-Class Test #3 2026/2027 study document provides a comprehensive 19-page question-and-answer review centered on cancer biology, lung cancer, epidemiological research, cancer health disparities, social determinants of health, and tobacco-related public health policy. The material begins with foundational cancer concepts, including uncontrolled cellular growth, apoptosis, differences between normal and cancer cells, environmental, behavioral and genetic cancer risk factors, age-related cancer risk, and disparities in cancer incidence. A major section examines epidemiology and cancer research methods through the relationship between smoking and lung cancer. The document reviews the Doll-Hill study and prospective cohort methodology while distinguishing cross-sectional, cohort, case-control, ecological, observational, experimental, randomized, double-blind, placebo-controlled, and community trials. It also explains exposure as an independent variable and outcome as a dependent variable, providing students with terminology needed to interpret epidemiological evidence and study designs. The cancer-biology material explores the cell cycle, oncogenes, tumor suppressor genes, genetic mutations, cancer development, angiogenesis, apoptosis resistance, cellular immortalization, invasion and metastasis, epithelial-mesenchymal transition, immune evasion, tumor-promoting inflammation, genome instability, and altered energy metabolism associated with the Warburg effect. The document reviews the major hallmarks of cancer and explains mechanisms cancer cells use to achieve growth-factor independence, suppress anti-growth signaling, induce angiogenesis, evade immune destruction, and maintain replicative potential. There is particularly detailed coverage of lung cancer and small-cell lung cancer (SCLC). Topics include lung anatomy, respiratory and conducting zones, SCLC and non-small-cell lung cancer, smoking as a risk factor, prognosis, common symptoms such as cough, dyspnea and hemoptysis, TP53 and RB1 tumor-suppressor genes, tumor biopsy, TNM classification, lung cancer stages 1–4, metastasis, and treatment approaches involving surgery, radiotherapy, chemotherapy, chemoradiotherapy and immunotherapy. The final sections connect cancer with population health and health equity. They address equality versus equity, justice, the five social determinants of health, socioeconomic and environmental influences on health, healthcare access, education, neighborhood conditions, the equity ecosystem, the Theory of Change model, racial disparities in lung cancer, insurance status, occupational exposure, intersectionality, smoking patterns by education and income, and the economic externalities of tobacco use. The material concludes with public-health approaches to smoking, including information campaigns, tobacco taxation, and place-based smoking restrictions.
