– the study of tumors or neoplasms

Oncology

5

common term for all malignant tumor

cancer

6

means crab in latin

cancer

7

Abnormal mass of tissue


neoplasm

8

Growth exceeds and uncoordinated with that of the normal tissues

neoplasm

9

Persists in the same excessive manner after cessation of stimuli which evoked the change

neoplasm

10

Results from heritable genetic alterations that are passed down to the progeny of the tumor cells

neoplasm

11

Autonomous and progressive growth

neoplasm

12

Entire population of cells within a tumor arises from a single cell that has incurred a genetic change (clonal)

neoplasm

13

2 basic components of tumors (benign or malignant)

parenchyma
stroma/non-neoplastic stroma

14

basic components of tumors
made up of transformed or neoplastic cells

Parenchyma

15

basic components of tumors:
determines the biologic behavior of the neoplasm

Parenchyma

16

it is the component from which the tumor derives its name.

Parenchyma

17

basic components of tumors:
made up of connective tissue and blood vessels

Stroma / Non-neoplastic stroma

18

basic components of tumors:
carries the blood supply and provides support for the growth of parenchymal cells and is therefore crucial to the growth of the neoplasm.

Stroma / Non-neoplastic stroma

19

benign hollow cystic masses; typically they are seen in the ovary.

Cystadenomas

20

are benign epithelial neoplasms, growing on any surface, that produce microscopic or macroscopic finger-like fronds.

Papillomas

21

mass that projects above a mucosal surface, as in the gut, to form a macroscopically visible structure.

Polyp

22

Although polyps is commonly used for benign tumors, some malignant tumors may also appear as polyps. T OR F

TRUE

23

– this term is applied to benign epithelial neoplasms producing gland patterns and to those derived from glands but not necessarily exhibiting gland patterns.

Adenoma

24

A benign epithelial neoplasm arising from renal tubule cells and growing in glandlike patterns would be termed an , as would a mass of

adenoma

25

benign epithelial cells that produces no glandular patterns but has its origin in the adrenal cortex would be termed as

adenoma

26

– malignant neoplasms arising in mesenchymal tissue or its derivatives

Sarcomas

27

malignant neoplasms of epithelial cell origin with the consideration that the epithelia of the body are derived from all three germ layers

Carcinomas

28

all malignant neoplasm arising from the epithelia derived from all three germ layers are considered ---

carcinomas

29

* The mesoderm may give rise to carcinomas (epithelial) only. TRUE OR FALSE

FALSE. May be both
The mesoderm may give rise to carcinomas (epithelial) and sarcomas (mesenchymal)

30


– denotes a cancer in which the tumor cells resemble stratified squamous epithelium.

Squamous Cell Carcinoma
