Cancer
.
- 1.You only need one mutation to cause cancer.
- A.
True
- B.
False
- 2.Normal genes that slow down cell division, repair DNA mistakes, trigger cell suicide. When one of the genes are mutated, cells grow rapidly which can lead to cancer.
- 3.A mutation or overexpression of certain normal genes called proto-oncogenes.
- 4.Oncogenes can contribute to the growth of a tumour by:
- A.
Causing unregulated cell division (due to absence of normal growth signals).
- B.
Suppressing cell division (due to absence of normal growth signals).
- C.
Triggering excessive cell suicide
- 5.Benign tumours are cancerous. They are true tumours that can change shape, destroy tissue, and have the potential to metastasise.
- A.
True
- B.
False
- 6.Benign tumours are different to malignant tumours because:
- A.
They are not aggressive, do not attack, and do not spread.
- B.
They are aggressive and can spread.
- 7.When cancers spread to other tissues. It is life-threatening and difficult to treat.
- 8.The origin of leukaemia is:
- A.
Bone marrow
- B.
Epithelial cells
- C.
Myosarcoma
- D.
Sarcoma
- 9.What defects are common to all cancer cells (tick all that apply)
- A.
Uncontrollable cell growth
- B.
Multiple mutations
- C.
Evade cell death
- D.
Process nutrients
- E.
Avoid detection
- F.
Invade tissue
- G.
Bladder
- 10.What are the differences between normal cells and cancer cells?
- A.
Normal cells grow and divide- cancer cells ignore communication cells from neighbouring cells and keep growing, they don't die.
- B.
Normal cells are immortal- cancer cells ignore communication cells from neighbouring cells and die rapidly
- C.
Normal cells metastasise- cancer cells ignore communication cells from neighbouring cells and commit excessive cell suicide
