Neoplasia
Abnormal growth of a tissue into a mass. Cells are no longer under the control of homeostatic growth (external and/or internal factors).
Tumour
Swelling or growth. Does not have to be neoplastic.
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)
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
In-situ tumour
Swelling that is:
- arising in the epithelium
- include malignant cells
- remains in the epithelial layer, ie non-invasive
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.
Fibroma
Benign tumour of fibrous tissue (benign with mesenchymal origin = -oma)
Lipoma
Benign tumour of fat tissue
Benign with mesenchymal origin = -oma
Chondroma
Benign tumour of cartilage
Benign with mesenchymal origin = -oma
Adenoma
Benign tumour of glandular epithelium
Papilloma
Benign tumour of the protective epithelium
Astrocytoma
Benign tumour of astrocytes
Benign tumour with nervous tissue origin = -oma
Fibrosarcoma
Malignant tumour of fibrous tissue
Malignant with mesenchymal origin = -sarcoma
Liposarcoma
Malignant tumour of fat tissue
Malignant with mesenchymal origin = -sarcoma
Chondrosarcoma
Malignant tumour of cartilage
Malignant with mesenchymal origin = -sarcoma
