17

What is the difference in growth pattern between benign and malignant tumours?

Benign = non invasive
Malignant = invasive

18

What differs with regards to the capsule in benign and malignant tumours?

- Benign have an intact capsule
- Malignant have no capsule/capsule breached

19

Whats the difference between cell functionality of malignant and benign tumours?

Benign = similar to normal cells

20

What are the 4 properties of cancer cells? (AG AC AF I)

- Abnormal structure
- Independent growth

21

What are the 4 ways cancer can spread around the body?

- Local
- Lymphatic
- Blood

22

Describe local spread

- Malignant tumour invades surround connective tissue

23

Describe lymphatic spread

- Tumour cells adhere to blood vessels
- Penetrate them and pass to lymph nodes forming a metastasis

24

Describe blood spread

- Tumour cells invade blood, forms metastasis in secondary tissue
