CANCER
Ms. Kelly
8th Grade Health
Journal #6:
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

Group of cells that grow together to
form a mass
No apparent function
– BENIGN: grows harmlessly without
spreading

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

– Risk factors (certain ones more common
than others)
– Etc…

ENVIRONMENTAL
– CARCINOGENS:
cancer-causing agents
Alcohol
Smoke/chewing
tobacco
Radiation (X-Rays)
Nitrites (smoked
meats)
Sun (UV Rays)
BIOLOGICAL
– Family tendencies
– Risk increases with
age
– Others biological
causes
Asbestos
Radon
Pesticides
Additives

If you could go
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/

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?

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
ABCDE’s of Melanoma Detection
– A: Asymmetry
– B: Border
– C: Color
– D: Diameter
– E: Elevation
