1

Neoplasia

Abnormal growth of a tissue into a mass. Cells are no longer under the control of homeostatic growth (external and/or internal factors).

2

Tumour

Swelling or growth. Does not have to be neoplastic.

3

Benign tumour

Swelling that is;
- growing slowly (usually) (dormancy) and locally
- non-invasive of the tissue, grow by expansion
- made of cells that are well-differentiated
- does not spread systemically (mestatisis)

4

Malignant tumour

Swelling that is;
- growing at either a slow or fast rate
- growing by invasion
- show signs of anaplasia (non-differentiated cells)
- able to metastasis

5

In-situ tumour

Swelling that is:
- arising in the epithelium
- include malignant cells
- remains in the epithelial layer, ie non-invasive

6

Cancer

A malignant tumour with the capacity of invasion of the local tissue/organ and systemic spread by metastasis.

A disease of all vertebrae spp.

Cancer comes from crab shape - invasion.

7

Fibroma

Benign tumour of fibrous tissue (benign with mesenchymal origin = -oma)

8

Lipoma

Benign tumour of fat tissue

(Benign with mesenchymal origin = -oma)

9

Chondroma

Benign tumour of cartilage

(Benign with mesenchymal origin = -oma)

10

Adenoma

Benign tumour of glandular epithelium

11

Papilloma

Benign tumour of the protective epithelium

12

Astrocytoma

Benign tumour of astrocytes

(Benign tumour with nervous tissue origin = -oma)

13

Fibrosarcoma

Malignant tumour of fibrous tissue

(Malignant with mesenchymal origin = -sarcoma)

14

Liposarcoma

Malignant tumour of fat tissue

(Malignant with mesenchymal origin = -sarcoma)

15

Chondrosarcoma

Malignant tumour of cartilage

(Malignant with mesenchymal origin = -sarcoma)

16

Adenocarcinoma

Malignant tumour of the glandular epithelium

17

Carcinoma

Malignant tumour of the protective epithelium
