Neoplasia 1 Nomenclature/Benign/Malignant/Epidemiology Flashcards
Whats a neoplasia?
Tumor?
Oncology?
neoplasm can be defined as adisorder of? triggered by? affecting how many origin cells?
Two basic components of tumors?
benign tumors def?
naming? fibrous? cartilage?
epithelium? renal tubular?
benign epithelial neplasms produce what?
what is a polyp?
if the polyp is glandular?
Malignant tumors? def and what they do?
malignant naming
solid mesenchymal tissue?
blood-forming?
epithelial/germ layers?
squamous cell carcinoma is what then?
adenocarcinoma?
mixed tumors are what? all arise from what?
most neoplasms even mixed composed of cells from what? the exception? these originate from?
Inappropriately named cancers? 4
wrongly named benign? 2
what is differentiation?
what is a lack of differentiation?
spectrum of differentiation?
hallmark of malignancy? (as related to malignancy)
Anaplasia associated with what other morphologic changes? 5
p-what is it?
anm- what is it normally? here?
M- doesnt necessarily indicate a tumor is what? more important in malig is presence of?
lp- what is it?
other changes- require what? a result of lack is?
if a cell has differentiation how does this affect function compared to normal?
if anaplastic? so can produce what?
cells in benign vs cancer and the above?
Metaplasia is what? usually found in association with?
dysplasia is what? characterized by what changes? 2
dysplastic cells exhibit?
Dysplastic squamous epithelium- what do you see?
what is carcinoma in situ?
at what point invasive?
does dysplasia always go to cancer?
if metaplastic is it dysplastic?
the growth of cancers is accompanied by what of surrounding tissue? 3
benign tumor growth? ofter form what? this creates a?
an exception?
Malignant tumors and surrounding tissues? can they have fibrous capsule?
next to development of metastases what is most reliable feature that differentiates between cancer and benign tumor?
this makes what hard?
In situ epithelial cancers similar to malignant cancer?
Metastasis is what?
likelihood primary tumor metastasizes correlates with? 4
are there exceptions?
is there a cancer thats always malignant?
pathways of spread. also called? the 3 pathways?
seed- what is it? most often where? characteristic of what type of cancer?
Pathways of spread
lymphatic spread- what is it? most common path for what type of cancer? also?
is it bad to do a full axillary lymph dissection?
do what instead? (name) what are these?
regional nodes importance in cancer?
why enlarged?
enlarged LN mean dissemination?
Pathways of spread
Hematogeneous spread- typical of what type of cancer? also? more likely to get penetrated?
tumor cells often come to rest where? most frequently involved?
if near vertebral column?
cancer that has propensity for invading veins? ex? 2
histo evidence of penetration of small vessels near primary neoplasm is what?
