Question 40

cancer that doesnt invade the basement membrane

Answer 40

noninvasive carcinoma in situ

Question 41

noninvasive carcinoma in situ

Answer 41

cancer that doesnt invade the basement membrane

Question 42

degrees of differentiation - what does this mean - types (3)

Answer 42

- how much it looks like original tissue - well differentiated (look more like normal cells - behave better) - poorly differentaiated - anaplastic= original cell type is unknown

Question 43

anaplastic

Answer 43

original cell type is unknown so dont know level of differentiation

Question 44

well/poorly differentiated

Answer 44

slightly/well differentiated from original tissue well differentiated= looks like normal cells (behaves more benignly) poorly differentiated = looks less like normal cells (behaves more malignantly)

Question 45

neoplasm construction

Answer 45

neoplastic cells- normally monoclonal (genetically identical to parent) stroma - mechanical supprt + framework- connective tissue. built from growth factors from neoplasm

Question 46

commonly metastases to bone

Answer 46

BLT - breast - lungs - thyroid KP nuts - kidney - prostate +renal

Question 47

metastases arrive in lung

Answer 47

systemic loop to large heart vena cava and large pulmonary arteries so lodges in small lung capillaries

Question 48

where do gut/colon tumours metastasise to?

Answer 48

liver, via the large portal vein into smaller liver capillaries where it can lodge so liver acts as 'tumour filter'

Question 49

do malignant tumours have a) growth increase compared to growth of rest of body b) cell division increase

Answer 49

B! | mitotic activity increases

Question 50

where do tumours go on to from lung venules

Answer 50

anywhere
