Flashcards in cancer/HIV Deck (37):
1

a set of diseases in which abnormal body cells multiply and spread in uncontrolled. forming a tissue mass called a tumor

cancer

2

the process by which malignant body cells proliferate in number and spread to surrounding body tissues

metastasis

3

cancer of the epithelial cells that line the outer and inner surfaces of the body--- breast, prostate lung SKIN cancer

carcinoma

4

cancer that strikes muscles bones and cartilidge

sarcoma

5

cancer of the bodies lymph system

lymphoma

6

cancer of the blood and blood producing system

leukemia

7

a cancer causing agent such as tobacco, radiation, environmental toxin

carcinogen

8

light absorbing pigments that give carrots, tomatos and other foods their color and are rich sources of antioxidant viatamins

carotenoids

9

a potentially deadly form of cancer that strikes the melatonin containing cells of the skin

melanoma

10

the over all ability of the immune system at any given time to defend the body against the harmful effects of foreign agents

immunocompetence

11

the theory that cells of the immune system play a monitoring function insearching for and destroying abnormal cells such as those that form tumors

immune surveillance theory

12

chemotherapy in which medications are used to support or enhance the immune systems ability to selectively target cancer cells

immunotherapy

13

the use od 1 or more external devices to assist in relaxation and the formation of clear strong positive images

guided imagery

14

a rare cancer of blood vessels serving the skin mucous membranes and other glands in the body

kaposis sarcoma

15

a worldwide epidemic such as aids

pandemic

16

a virus that copies its genetic info onto the dna of a host cell

retrovirus

17

all the DNA info for an organism the human genome consists of approximately and billion DNA sequences

genome

18

an aids related syndrome involving memory loss, confusion and personalty changes

aids dementia complex

19

the 1st anti aids drug a reverse transcrips inhibitor

zidovudine(AZT)

20

–Retrovirus: injects genome into lymphocytes
so that it reproduces when the cells are activated
– Worldwide pandemic, 11 people infected/minute

HIV (Human Immunodeficiency Virus)

21

–Body’s CD4 lymphocytes are destroyed, leaving the
victim vulnerable to opportunistic infections

• AIDS (Acquired Immune Deficiency Syndrome)

22

A genetic disease in which the blood fails to clot
quickly enough, causing uncontrollable bleeding

• Hemophilia

23

a virus that
copies its genetic
information onto the DNA
of a host cell

retrovirus

24

HIV infects mostly ___
tissues
• HIV infects and destroys a
type of lymphocyte called
the_____

lymph tissues

Tcell

25

--immune system detroys most virus no symptoms
--(latency period)- t cell concentration falls, HIV concentration rises, swollen lymph nodes
--t cells reduced, impaired immune function; infections
--almost all natural immunity is lost; alds occurs

stages of HIV

26

AIDS progresses more slowly
among those with strong immune systems

Immunocompetence

27

Multiple anti-HIV drugs that prevent HIV replication

• The HAART Regimen (highly active antiretroviral
therapy)

28

– Women involved in casual sexual relationships are 11 times
more likely than women in more committed relationships to
maintain safer sexual behaviors

aids complacency

29

Subjective reinforcement of unprotected anal intercourse
strongly predicts condom use among gay and bisexual men
(Kelley & Kalichman, 1998)

• Sensation-seeking personality

30

 Also referred to as non-invasive because cancer is found in the lining
of a breast duct but has not spread to other tissues in the breast.
 Stage 0 is also called “ductal carcinoma in situ” or “DCIS.”

stage 0 breast cancer

31

Cancer is present in the breast tissue.
 In some cases, Stage I cancer has not spread outside the breast and
in other cases, there may be cancer in the lymph nodes near the
breast.
 Lymph nodes are small bean-sized and bean shaped organs located
throughout the body that work as a part of our lymphatic system .
 Lymph nodes are like filters that fight infection.

stage 1 breast cancer

32

-- Cancers in the breast and lymph nodes are larger than stage I cancers.
Also, larger cancers may be found in more of the lymph nodes.

--Tumors in the breast and lymph nodes are larger than stage II tumors
and tumors are found in even more lymph nodes.
 The cancer may have spread to the chest wall or the skin of the breast,
and there may be swelling or an open sore.

--- Invasive breast cancer that has spread beyond the breasts and lymph
nodes to other parts of the body.

--described as “advanced,” “metastatic,” or

stage 2

stage 3

stage 4

stage 5

33

most common type of cancer

carcinoma

34

Which type of biomedical intervention generally offers the greatest chance for cure with most types of cancer?

surgery

35

The spread of malignancy from one part of the body to another is called:

metastasis

36

Environmental toxins in the air, soil, and water contribute to fatal cancers, mostly ________ and ________ cancer.

bladder and lung

37

a rare form of lymphoma that spreads from a single lymph node

hodgkins disease
