Questions and Answers

What does the term 'metastasis' refer to in cancer biology?

  • The initial formation of a tumor
  • The presence of cancer in the bloodstream
  • The spread of cancer cells to other parts of the body (correct)
  • The removal of a tumor surgically
  • Which of the following correctly describes 'benign' tumors?

  • They invade surrounding tissues aggressively.
  • They have a high potential for metastasis.
  • They are non-cancerous and do not spread. (correct)
  • They are always fatal to the host.
  • Which gene categories are commonly mutated in oncogenesis?

  • Only proto-oncogenes
  • Oncogenes, tumor-suppressors, and genome maintenance genes (correct)

    Study Notes

    Cancer Learning Objectives

    • Define key terms: aneuploid, oncometabolite, benign, malignant, metastasis, indirect/direct-acting carcinogens, "multi-hit" model, oncogenes, protooncogenes, tumor suppressors, genome maintenance genes
    • Describe cancer cell biological hallmarks
    • Explain how genetics and mutations contribute to cancer predisposition/progression
    • Classify malignant tumors (carcinomas or sarcomas)
    • Detail the processes of cancer initiation, progression, and metastasis
    • Identify gene categories mutated in oncogenesis
    • Explain how deregulated cellular/molecular mechanisms contribute to cancer development

    Cancer Text Excerpt

    • Lodish et al. (2021), Chapter 25
    • Verse (Matthew 5:29-30): Losing a body part is better than losing your whole body due to sin (NIV)
    • Surgical removal of cancerous parts is sometimes necessary to save the rest of the body—a medical analogy
    • Sin affects the entire body, not just specific parts
    • Christ's death is a complete sacrifice to eliminate sin (Galatians 2:20)
