Tumour Nomenclature and Introduction Flashcards

1
Q

Neoplasia

A

Uncontrolled, abnormal growth of cells or tissues in the body

  • Abnormal Mass of Tissue growing at rate exceeding normal tissue
  • Persists in excessive manner after cessation of stimulus which evokes change

Q

Dysplasia

A

Presence of abnormal cells within tissue that is not cancerous but may become cancer

They regress after a stimulus is lost

Q

Hyperplasia vs Neoplasia

A

Neoplasia continues after loss of stimulus

Q

Importance of differentiation in cancer

A

Failure to achieve cellular differential is a feature of malignant neoplasms, allows prediction of a tumour’s likely behaviour

Q

Differentiation of a tumour

A

Used to describe difference in appearance between cells of a tumour and the cell types they are derived from

Well differentiated tumours have a better prognosis

Q

Compare: Well Differentiated Tumours, Poorly Differentiated Tumours, Undifferentiated/Anaplastic Tumours

A

Well differentiated tumour: Composed of cells which very closely resemble the cell of origin

Poorly differentiated tumour: Composed of cells which bear little resemblance to the cell of origin, but just enough to enable the original cell type to be identified

Anaplastic tumour: Composed of cells which are so undifferentiated that their cell of origin is unknown
