

Have you personally been affected by
cancer? (I.e.: You, yourself, had a
scare, maybe a family member, friend,
coach, etc.) If so, explain your
connection as you feel comfortable…
If you don’t have a personal
connection, discuss how you might
feel if someone you knew was
diagnosed with a life-threatening
illness…

Definition


Groups of abnormal
cells that multiply
out of control
Due to something
wrong with size,
shape, or
DNA/function
Tumors


Group of cells that grow together to
form a mass
No apparent function
– BENIGN: grows harmlessly without
spreading
– MALIGNANT: Abnormal cells that spread to
other parts of the body (CANCEROUS!)

React the following statistics. How do
they make you feel? Are you
surprised, do they shock you, etc.?
– In 2014, about 585,720 Americans are
expected to die of cancer (almost 1600
people per day). It is the second most
common cause of death in the US.
– The 5-year survival rate for all
cancers between 2003 and 2009 is
68% (up from 49% in the 70s).

Metastasis

Spreading of
cancer from
localized area
to other parts
of the body
via lymph and
blood
Biopsy

Removal of a small amount of tissue
for examination under a microscope
JOURNAL:

You completed the “Faces of Cancer”
activity last class… explain what you
learned from the activity. Consider:
– Trends, if any, you noticed (re: family
history, age, etc.)
– Risk factors (certain ones more common
than others)
– Etc…


Alcohol
Smoke/chewing
tobacco
Radiation (X-Rays)
Nitrites (smoked
meats)
Sun (UV Rays)

BIOLOGICAL
– Family tendencies
– Risk increases with
age

anywhere in the
world, where would
you go and why??
Latency Period



Period of time it takes for the cancer
to develop
Time of exposure to time symptoms
appear
Can be 20-30 years before the cancer
is detected
Prevention




Avoid tobacco
products
Avoid excess
alcohol
consumption
High fiber/low fat
diet
Avoid stress



Avoid prolonged
exposure in the sun
(SPF 15 or higher)
Avoid too much
radiation
Physical check-ups/
self-exams
Cancer Fighting Foods

veggies (broccoli, cauliflower, cabbage)
Whole grains (whole wheat, brown rice)


Change in
bathroom habits

heal

Thickening or lump





difficulty swallowing
Obvious change in
wart or mole

Journal:

Use your notes and class discussions
to write a paragraph about what you
have learned so far. Consider:
– What is cancer?
– What causes it and/or is it preventable?
– What are some signs and symptoms?
How might you know if you have it?
– What might happen to your body
physically, mentally, and socially if you
were diagnosed with cancer?
Treatments

Surgery—removal
of tumor
– Cryosurgery is used
for mouth and skin
cancers (liquid
nitrogen)
Treatments (con.)

Chemotherapy—50 different drugs (IV,
pills, injection)
– Chemicals destroy cancer cells by
interfering with DNA without harming too
many normal cells
– Side effects: nausea, hair loss,
rashes
Treatments (con)

Radiation—Cancer cells more sensitive
than normal cells
– Most sensitive areas: bone marrow where
blood cells are made (sternum) and pelvic
area where reproductive organs located
Remission


Period of time when
person is symptomfree
Permanent remission:
5 years with no
reoccurrence
Melanoma


Most serious form of skin cancer
