Flashcards in Ch18&19 Deck (53):
1

dys-

bad: painful: difficult: abnormal

2

hyperplasia

abnormal increase in volume of a tissue or organ caused by the formation and growth of new normal cells.

3

eso-

inward

4

multiple myeloma

Multiple myeloma is a cancer in which antibody-producing plasma cells grow in an uncontrolled and invasive (malignant) manner.

5

ana-

up; apart; backward; again; anew

6

palliative

1. giving relief but not curing. 2. a drug with this effect.

7

meta-

change; beyond

8

radi/o

x-rays; radioactivity; radius (lateral lower arm bone)

9

anaplasia

loss of differentiation of cells and their orientation to each other, a characteristic of tumor cells;

10

adenocarcinoma

carcinoma derived from glandular tissue or in which the tumor cells form recognizable glandular structures.

11

encapsulated

Enclosed in a capsule or sheath.

12

carcinoma

a malignant new growth made up of epithelial cells tending to infiltrate surrounding tissues and to give rise to metastases.

13

dosimetry

scientific determination of amount, rate, and distribution of radiation emitted from a source of ionizing radiation.

14

sarc/o

flesh (connective tissue)

15

leuk/o

white

16

flat plate

jargon for plain film.

17

-oma

tumor; mass; fluid collection

18

scout film

a radiograph exposed before contrast medium is given, such as the preliminary film for an angiogram, urogram, or barium contrast gastrointestinal examination.

19

in situ

in its normal place; confined to the site of origin.

20

aden/o

gland

21

Hodgin's lymphoma

a rare lymphoma, a cancer of the lymphatic system.

22

papilloma

a benign tumor derived from epithelium. Papillomas may arise from skin, mucous membranes, or glandular ducts.

23

metaplasia

the change in the type of adult cells in a tissue to a form abnormal for that tissue.

24

apoptosis

the cessation of all physical and chemical processes that invariably occurs in all living organisms.

25

neoplasia

the formation of a neoplasm.

26

son/o

sound

27

Non-Hodgin's lymphoma

any neoplastic disorder of lymphoid tissue, NOT including hodgkin's disease.

28

lymphoma

any neoplastic disorder of lymphoid tissue, including hodgkin's disease.

29

peau d' orange

A swollen pitted skin surface overlying carcinoma of the breast in which there is both stromal infiltration and lymphatic obstruction with edema.

30

sarcoma

A tumor, often highly malignant, composed of cells derived from connective tissue such as bone, cartilage, muscle, blood vessel, or lymphoid tissue; sarcomas usually develop rapidly and metastasize through the lymph channels.

31

remission

diminution or abatement of the symptoms of a disease; the period during which such diminution occurs.

32

dysplasia

an abnormality of development; in pathology, alteration in size, shape, and organization of adult cells.

33

cachexia

a profound and marked state of constitutional disorder; general ill health and malnutrition.

34

interventional radiology

the branch of medical science dealing with use of x-rays, radioactive substances, and other forms of radiant energy in diagnosis and treatment of disease.

35

carcin/o

cancerous; cancer

36

excisional

surgery of or relating to an excision

37

exo-

out; away from

38

hetero-

other, different

39

hist/o

tissue

40

myel/o

spinal cord; bone marrow

41

benign neoplasm

a localized tumor that has a fibrous capsule, limited potential for growth, a regular shape, and cells that are well differentiated.

42

cry/o

cold

43

neo-

new

44

film badge

a pack of radiographic film or films worn as a badge, used for the detection and approximate measurement of radiation exposure of personnel.

45

incisional

a. A cut into a body tissue or organ, especially one made during surgery. b. The scar resulting from such a cut.

46

rhabdomyoscarcoma

a highly malignant tumor arising in striated muscle or in embryonal mesenchymal cells that exhibit differentiation along rhabdomyoblastic lines, including but not limited to the presence of cells with recognizable cross striations.

47

malignant neoplasm

a tumor that tends to grow, invade, and metastasize. The tumor usually has an irregular shape and is composed of poorly differentiated cells. If untreated, it may result in death.

48

leiomy/o

smooth (visceral) muscle

49

metastasis

1. the transfer of disease from one organ or part to another not directly connected with it. It may be due either to the transfer of pathogenic microorganisms (e.g., tubercle bacilli) or to the transfer of cells, as in malignant tumors. See also cancer. 2. a growth of pathogenic microorganisms or of abnormal cells distant from the site primarily involved by the morbid process. adj., adj metastat´ic.

50

onc/o

tumor

51

serum tumor markers

yep

52

leukemia

a progressive, malignant neoplasm of the blood-forming organs, marked by diffuse replacement of the bone marrow development of leukocytes and their precursors in the blood and bone marrow.

53

plain film

a radiograph made without use of a contrast medium.
