Cancer

Question 1

Cancer

Answer 1

Uncontrollable cell division

Question 2

Cause

Answer 2

Damage to the genes that control the cell cycle

Question 3

Become

Answer 3

Tumours

Question 4

Benign Tumours

Answer 4

grow very large but do not destroy surrounding tissue

Question 5

Maligant Tumours

Answer 5

destroy surrounding tissue
cells break away and spread through the blood
forming secondary tumours

Metastasis

Question 6

Dangerous

Answer 6

can develop its own blood vessels
can undergo metastasis
secondary tumours

Question 7

Treatment

Answer 7

some are terribly mutated so our body can destroy them

any cancer treatment will also kill our helathy cells

Question 8

Aims

Answer 8

to kill cancer cells without damaging healthy cells

target what makes them different

Question 9

What makes them different

Answer 9

uncontrollable cell division

Question 10

Chemotherapy

Answer 10

use of chemicals to treat cancer

Question 11

Cisplastin

Answer 11

cross links (joins) different DNA molecules in the cell with string covalent bonds

Question 12

Evastin

Answer 12

slows down the growth of new blood vessels

Question 13

Vinblastin

Answer 13

stops the joining of micro tubules to form the spindle

Question 14

Taxol

Answer 14

stops the shortening and contraction of the spindle

Question 15

Vinblastin and Taxol

Answer 15

stops division taking place

Question 16

Inhibiting division

Answer 16

stoppong division of other cells hits cancer harder than most other body cells

Question 17

Targets

Answer 17

stop spindle forming
stop spindle contracting
forming bonds between DNA molecules prevents division of sister chromatids
stop blood vessels forming to prevent metastasis
