Max fax placement
Reconstruction after surgical sections fo tumour
Encounter neoplasia in clinical career
What does Neoplasia mean
what does Tumour mean
what does Oncology mean
what is the biological definition of a neoplasm
What does persistence of tumour growth after removal of stimulus result from?
Cells accumulate genetic alterations
- unregulated growth
what does malignant mean
What does benign mean?
what does carcinogenesis require
hallmarks of cancer?
Label these components
what causes cancer
All have some agent or factor that destabilises the cell cycle
list some oncogenic pathogens
list carcinogenic substances
List radiation sources
Is age a factor in tumour development
what is obesity and how is it related to cancer
How could being overweight cause cancer
how is inheritance and cancer linked
what is the main distinguishing features of neoplasia
what are features of anaplasia
How is well, poor, undifferentiated defined
How is neoplasia classified, graded and stage
what is anaplasia
Describe these images
what is metaplasia
Epithelium can change from one cell type to another
Areas of natural transition in the body , for example change from squamous to glandular epithelium at certain sites
Also metaplasia in response to a stimulus
This examples shows changes in the bronchus form columnar to squamous
Barrett’s oesophagus - squamous to glandular in response to acid reflux
what is hypertrophy
what is hyperplasia
what is dysplasia
what is carcinoma in situ
Invasive malignancy -needs to breach the basement membrane
Barrier that separates the epithelium from the underlying lamina porporia and connective tissue which contains all the soft tissue in vessels
Once it breaches its carcinoma up to that points it dysplasia
what should we refer dysplasia to instead of pre malignant (histroric)
potential malignant
what is the rate of growth
Describe bending tumours compared to malignant tumours
how are tumours classified
describe different types of benign tumours
Describe what surface and glandular epithelial are used for
what are the rules of naming benign tumours
if the benign tumour is form glandular/secreotry/ductal epithelium
if bending tumour from non glandular/ non secretory surface epithelium then it is called
what is benign epithelial tumours classified as
what are malignant epithelial tumours called
what are maglignt epithelial tumours derived form glandular ductal epithelium called
What is malignant epithelia tumours derived from surface non-glandular epithelial are named by prefixing ………
Describe salivary gland tumours
what do you call malignant mesenchyme tumours
rules of malignant mesenchymal tumours
describe examples of other tumours
what are teratomas
describe precusro cell tumours
describe some Brain tumours
what is a hamartoma
