Q

Benign

A

growth is limited May cause damage if presses on nearby tissue. ex: kid has a benign brain tumor that causes extensive respiratory depression from increased pressure on the respiratory center

Q

angiogenesis is what and what stage does it happen in? (Initiation, promotion o Progression)

A

tumor forms blood vessels to provide access for oxygen & nutrients. This process is also called neovascularization. Happens in Progrssion stage

designated to fight neoplasms (cancer cells), they kill normal cells are well. Used as palliative care when tumor is too big to cure

Q

onocogenic viruses

A

cancer-causing viruses that change the DNA or RNA in a cell. (C Type RNA & Epstein-Barr virus)

22
Q

The development of cancer is linked to the failure of the normal immune system possible by?

A

Age, Tumor cells may not be recognized, tumor cells may suppress the immune system

23
Q

Rapid multiplying cells

A

Gi system, Hair, skin, bone marrow

24
Q

slow cells

A

breast, testies, ovaries

25
Q

DES Diethylstilbestrol is the cause of what type of cancer

A

vaginal carcinomas

26
Q

Stages of carcinogenesis

A

initiation, promotion, progression

27
Q

initiation stage of carcinogenesis

A

carcinogens alter the cell DNA-it can repair itself but if not it leads to promotion

28
Q

Promotion stage of carcinogenesis

A

repeated exposure causes the expression of mutant gene formation “on switch” for cellular growth

29
Q

Progression stage of carcinogenesis

A

exhibit increased malignant behaviors (invading, metastasizing)

30
Q

Carcinogens

A

agents that initiate or promote cellular transformation

31
Q

well differentiated

A

resemble normal cells. Grade 1. You can tell which cells they are, liver cells etc

32
Q

least differentiated

A

the loss of similarity to normal cells, Grade 4, cant tell which cells they came from

33
Q

Unproductive cellular alterations

A

hyperplasia, metaplasia,dysplasia, anaplasia, neoplasia. Can reverse after irritation is removed or can lea to malignancy esp with dysplasia

34
Q

T-lymphocytes

A

recognize tumor-associated antigens

35
Q

Lymphokines

A

produced by lymphocytes can kill cancer cells, & mobilize macrophages

36
Q

Interferon

A

produced by the body to fight viruses, has some antitumor properties

37
Q

Antibodies are produced by

A

B-Lymphocytes

38
Q

NK (Natural Killer) cells

A

major defense against cancer cells, they produce lymphokines & enzymes

39
Q

Incisional biopsy

A

part of tumor

40
Q

Excisional biopsy

A

all of tumor

41
Q

Tumor grading, G1, G2, G3, G4

A

resembles tissue of origin, moderately resembles tissue of origin, poorly resembles tissue of origin, undifferentiated

42
Q

Adenocarcinoma

A

glandular malignancy

43
Q

TNM staging is only good for which type of cancer

A

carinomas

44
Q

T is in situ

A

tumor is in the skin, not in tissue just skin

45
Q

T 1-4

A

tumors different size and shape

46
Q

most common spread of malignant cells

A

lymphatic spread

47
Q

N1a-N2a

A

regional node involvement no mets

48
Q

N1b-3b

A

regional node involvement suspect mets

49
Q

characteristics of cancer cells

A

nucleus is enlarged, surface enzymes aid in invasion & mets, loss of labeling antigens (self), ^rate of anaerobic metabolism, decreased inhibition (stop cell division when contacting another cell), defect in cell recognition & adhesion, loss of control in proliferation, increased mitotic index (large # of cells in mitosis), abnormal life span

50
Q

Origin of cancer cell

A

monoclonal origin ( arising from a single cell), Proto-oncogenes (“on-switch” for cell growth), Tumor suppressor genes (“turn-off switch” for unneeded cell growth
