Flashcards in cancer/HIV Deck (37):
a set of diseases in which abnormal body cells multiply and spread in uncontrolled. forming a tissue mass called a tumor
the process by which malignant body cells proliferate in number and spread to surrounding body tissues
cancer of the epithelial cells that line the outer and inner surfaces of the body--- breast, prostate lung SKIN cancer
cancer that strikes muscles bones and cartilidge
cancer of the bodies lymph system
cancer of the blood and blood producing system
a cancer causing agent such as tobacco, radiation, environmental toxin
light absorbing pigments that give carrots, tomatos and other foods their color and are rich sources of antioxidant viatamins
a potentially deadly form of cancer that strikes the melatonin containing cells of the skin
the over all ability of the immune system at any given time to defend the body against the harmful effects of foreign agents
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
chemotherapy in which medications are used to support or enhance the immune systems ability to selectively target cancer cells
the use od 1 or more external devices to assist in relaxation and the formation of clear strong positive images
a rare cancer of blood vessels serving the skin mucous membranes and other glands in the body
a worldwide epidemic such as aids
a virus that copies its genetic info onto the dna of a host cell
all the DNA info for an organism the human genome consists of approximately and billion DNA sequences
an aids related syndrome involving memory loss, confusion and personalty changes
aids dementia complex
the 1st anti aids drug a reverse transcrips inhibitor
–Retrovirus: injects genome into lymphocytes
so that it reproduces when the cells are activated
– Worldwide pandemic, 11 people infected/minute
HIV (Human Immunodeficiency Virus)
–Body’s CD4 lymphocytes are destroyed, leaving the
victim vulnerable to opportunistic infections
• AIDS (Acquired Immune Deficiency Syndrome)
A genetic disease in which the blood fails to clot
quickly enough, causing uncontrollable bleeding
a virus that
copies its genetic
information onto the DNA
of a host cell
HIV infects mostly ___
• HIV infects and destroys a
type of lymphocyte called
--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
AIDS progresses more slowly
among those with strong immune systems
Multiple anti-HIV drugs that prevent HIV replication
• The HAART Regimen (highly active antiretroviral
– Women involved in casual sexual relationships are 11 times
more likely than women in more committed relationships to
maintain safer sexual behaviors
Subjective reinforcement of unprotected anal intercourse
strongly predicts condom use among gay and bisexual men
(Kelley & Kalichman, 1998)
• Sensation-seeking personality
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
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
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
-- 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
most common type of cancer
Which type of biomedical intervention generally offers the greatest chance for cure with most types of cancer?
The spread of malignancy from one part of the body to another is called:
Environmental toxins in the air, soil, and water contribute to fatal cancers, mostly ________ and ________ cancer.
bladder and lung
