Flashcards in MOD 9.1 - Neoplasia 2 Deck (6):
1

What is metastasis?

The development of secondary malignant growths at a site distant from the primary site of cancer

2

How can metastasis travel to other sites?

- Through blood

- Through lymph

- Grow directly into the surrounding tissue

3

What is invasion of a metastasis?

- Cells pass through the basement membrane and extra cellular matrix

4

What is tumour burden?

- The number of cancer cells, size of a tumour or amount of cancer in the body

- Invasion + metastasis = ↑ tumour burden

5

Why does tumour burden not increase with benign tumours?

They don't metastasise

6

What is tumour dormancy?

Tumour cells are quiescent and therefore do not divide. They wait for an appropriate stimulus for proliferation
