1

neoplasia

a tumor

2

oncology

the study of tumors

3

cancer

a malignent tumor

4

what is the nomenclature of benign tunmors

usually end in oma

5

what is a fibroma

benign tumor that is fibrous or developed CT

6

what is a chondroma

hyaline cartilage benign tumor

7

what is a adenoma

benign tumor of epithelial cell glandular or glandular derived

8

what is a hemangioma

benign tumor of blood vessels

9

what is a lymphoma

benign tumor of lymphoid tissue

10

what is a papiloma

benign tumor of epithelial of the skin or mucous membrane with finger like projections

11

what is polyp

benign protrusion from a mucous membrane

12

what is a sarcoma

malignant tumors derived from derivatives of mesenchymal connective tissues

13

What is carcinoma

malignant tumors derived from epithelial cells

14

What is a mesothelioma and melanoma

two examples of malignant tumors that do not follow the rule

15

what is a mixed tumor

example would be the pleomorphic tumor of the parotid contains several types of cells in this case epithelial celsl and conncetive tissue stroma occurs due o diverggent differentiation

16

what is a teratoma

tumor derived from more that one germ layer. So more than one type of tissue is found in the tumor teeth and hair and fat can be benign or malignent

17

what are the characteristics of neoplasms

differentiation and anaplasia, rate of growth, local invasion, and metastasis.

18

what is differentiation

how it looks compared to normal cells both in structure and function.

19

what is anaplasia

is a state where tumor cells lack differentiation

20

what is pleomorphism

cells and nuclie are variable in size and shape

21

what are the characteristics abnormal nuclear structure

nuclie will have an abundance of DNA and are hyperchormoatic

22

what is different in anaplasia with mitosis

a large number of mitotic spindsl and may be tripolar or quadpolar

23

what happends to polarity in anaplasia

it can be lost so the cells lose organization

24

what does it mean to be in situ with a cancer

that it has not yet left the basement membrane or the area where its supposed to be.

25

what is direct seeding of cavities or surfaces of a malignent tumor

when it directly invades the cells next to to.

26

what is hematogenous

when the malignant tumor is spread through the blood vessels common in liver and lungs due to volume of blood flow

27

what is perineural invasion and spread

when the cancer invades the ct coat of nerves and travel around the nerve, common in head, neck prostate and pancrease cancers and can generate pain.

28

know the table in the handout

good job

29

what is the most common site of cancer

men prostate women breast

30

what is the second most common site of cancer

lung cancer both

31

what is the third most common site of cancer

colon and rectum in both again

32

what cancer has the highest cause of death

lung for both

33

what cancer has the second most causes of death

men prostate women breast

34

what cancer has the third most cause of death

colon and rectum in both again

35

what is the most common location of the adenocarcinoma of the prostate

the peripheral zone usually the posterior location

36

what are serum markers for prostate cancer

PSA and PSAP

37

how does prostate cancer usally spread

hematogenous spread to the vertebral column

38

where are half of all breast cancers found

in the upper lateral quadrent

39

what type of cancer are most breast cancers

adenocarcinomas

40

what are the two broad categories of breast cancer

carcinoma in situ and invasive carcinoma

41

where do most of the lung cancer origanate

primary secondary and tertiatry bronchi 75 percent

42

what are the four main categories of lung cancer

squamous cell carcinoma with pearls found in smokers and men, adenocarcinoma most common in women and non smokers. Small cell carcinoma highly malignant, large cell carcinoma undifferentiated.

43

what are the two architecture types of colonic adenoma

pedunculated tubular and sessile villous and villous is more aggressive

44

what sites are more common in colonic adenomas

ascending 38 and sigmoid and rectum 35 transverse and descending both 18 percent
