The 20 questions

  1. Cancer is caused by changes in cells that lead to what process?

    • Uncontrolled cell division
    • Controlled cell death
    • Slower cell growth
    • Rapid cell differentiation

  2. Which type of tumour is contained in one area and does not invade other tissues?

    • Metastatic tumour
    • Benign tumour
    • Malignant tumour
    • Secondary tumour

  3. Which type of tumour invades neighbouring tissues and spreads to other body parts?

    • Encapsulated tumour
    • Benign tumour
    • Dormant tumour
    • Malignant tumour

  4. How do malignant cells travel to different parts of the body?

    • Inside digestive juices
    • Through nerve fibres
    • In the blood
    • In the saliva

  5. What is formed when malignant cells spread through the blood to new organs?

    • Secondary tumours
    • Membranous tumours
    • Primary tumours
    • Benign tumours

  6. Besides genetic factors, what other type of factor influences cancer risk?

    • Climatic factors
    • Blood group
    • Geographical area
    • Lifestyle factors

  7. Which other type of risk factor is linked to some cancers?

    • Chlorophyll deficiency
    • Genetic risk factors
    • Lack of stomata
    • Excess xylem

  8. Which of these is a cancer risk factor linked to lifestyle?

    • Smoking
    • Vaccination
    • Exercise
    • Good nutrition

  9. What structural feature usually encloses a benign tumour in one area?

    • A cell wall
    • A protein coat
    • A membrane
    • A lipid sheath

  10. Why are malignant tumours considered more dangerous than benign tumours?

    • They stay contained
    • They lack DNA
    • They can spread
    • They grow slower

  11. What cell process occurs uncontrollably during cancer development?

    • Cell division
    • Cell respiration
    • Protein synthesis
    • Cell differentiation

  12. A tumour is found to be contained in a membrane and does not invade nearby tissue. What is it most likely to be?

    • A benign tumour
    • A malignant tumour
    • A virus particle
    • A secondary tumour

  13. What type of factors increase the likelihood of developing cancer?

    • Safety factors
    • Risk factors
    • Growth factors
    • Limiting factors

  14. Which microorganism living inside cells can act as a trigger for cancer?

    • Protists
    • Bacteria
    • Viruses
    • Fungi

  15. Which statement is true regarding the movement of benign tumour cells?

    • They form secondaries
    • They do not spread
    • They invade tissues
    • They travel in blood

  16. How do cancer cells reach other tissues to form secondary tumours?

    • Through the blood
    • Via digestive tract
    • Through air passages
    • Along nerve cells

  17. Why are benign tumours usually easier to remove surgically than malignant tumours?

    • They stay contained
    • They grow faster
    • They are liquid
    • They lack cells

  18. How do malignant cells travel to form secondary tumours in distant organs?

    • In the blood
    • In digestive juices
    • In air passages
    • In nerve cells

  19. Which environmental factor is a direct risk factor for developing cancer?

    • Excess sugar
    • High blood pressure
    • Carbon monoxide
    • Ionising radiation

  20. What is formed when malignant cells spread through the blood to other organs?

    • Protective membranes
    • Secondary tumours
    • Enzyme complexes
    • Benign tumours
