📝 Exam Tips: Cancer Questions
Question Types
- Explanation: Link cancer to normal cell division control — use process words ("leads to," "results in," "causes")
- Comparison: Benign vs malignant — focus on spreading ability. Use "whereas," "in contrast," "unlike"
- Treatment: Explain mechanisms at the cellular level, discuss selectivity and side effects
Command Words
- Explain: Give reasons why cancer develops or spreads
- Compare: Similarities AND differences between tumour types
- Evaluate: Assess effectiveness of different treatments — include limitations
Common Mistakes
- Not naming the specific gene types (oncogenes, tumour suppressors) when asked
- Saying "cancer cells spread" without explaining HOW (through blood/lymph to form secondary tumours)
- Forgetting to explain WHY chemotherapy causes side effects (it targets all rapidly dividing cells, not just cancer)
📋 Edexcel 1BI0 Specific Advice:
- Edexcel Paper 1 (1BI0/1) — Topic 2 — presents cancer questions using data or a patient scenario; always reference the stimulus as well as your own biology when the question says "use the information"
- For treatment side-effect questions, the key mark is linking the treatment mechanism to normal rapidly-dividing cells — specifically name examples (gut lining, hair follicles) for higher-mark answers
- Edexcel "Suggest" questions on genetic risk expect you to name the relevant gene types: inherited mutations in tumour suppressor genes mean the normal braking mechanism for cell division is absent from birth
- "Uncontrolled cell division" is the key mark-scheme phrase in Edexcel answers — use it explicitly rather than paraphrasing
