Q

What happens when there is a blood spread of tumours?

A

Tumour cells invade blood cells and then eventually tissues before forming secondary tumours

17
Q

What happens when there is a trans-coelomic spread of tumours?

A

Tumour cells spread across body cavities

18
Q

What is dysplasia?

A

A pre-malignant change which can indicate that a tumour is becoming malignant.

19
Q

Where is dysplasia identified?

A

In the epithelium without invasion

20
Q

How do cells become disorganised in dysplasia?

A

Increased nuclear size
Increased mitotic activity
Abnormal mitosises

21
Q

What is the order of the stages in the cell cycle?

22
Q

What is carcinogenesis?

A

The production of cancer cells caused by the mutation of genetic material

23
Q

What happens when the cyclin pRb pathway is mutated?

A

Uncontrolled cell proliferation

24
Q

What happens when the p53 pathway is mutated?

A

Cell continues to divide even if the cell has been damaged, so the damage is carried on in the new cells.

25
What does the Human Papilloma virus cause?
Cervical cancer
26
How do alkylating agents fight cancer?
Binding guanine bases covalently to prevent DNA replication
27
How do Antimetabolites fight cancer?
Integrate into nuclear material or bind irreversibly to vital enzymes to prevent division
28
How do Vinca Alkaloids fight cancer?
Prevent metaphase by preventing spindle formation
29
How do Taxanes fight cancer?
Promote spindles then freeze them
30
How do Antimitotic Antibiotics fight cancer?
Prevent DNA and RNA synthesis
