2. What is Melanoma?
Melanoma is a very serious form of
skin cancer.
Melanoma is cancer of the
melanocytes.
Melanocytes are located in the
Stratum Basale and produce melanin.
Brought to you by
3. Melanocytes
When skin is exposed to sunlight,
melanocytes produce more pigment,
causing the skin to tan.
Sometimes, clusters of melanocytes form
noncancerous (benign) growths called
moles.
Moles can be either flat or raised, round
or oval, and are smaller than a pencil
eraser.
– Generally harmless, but can become cancerous
Brought to you by
5. What is cancer?
Cancer is abnormal cell growth.
The mass of extra cells forms a
growth or tumor.
Tumors can be either benign or
malignant.
Benign tumors are not cancer. They
often can be removed and, in most
cases, they do not come back.
Brought to you by
6. Malignant Tumors
Malignant tumors are cancerous.
Cells can invade and destroy surrounding
tissue.
Cells can also break away from a malignant
tumor and enter the bloodstream.
When cancer spreads (metastasizes) to
other parts of the body, the new tumor
has the same kind of abnormal cells and
the same name as the original tumor.

9. Causes of Melanoma
90% of all melanomas are linked to UV
radiation. (Sun exposure)
8% are due to chromosomal abnormalities
About 2% are unknown

10. Risk Factors
Family history of melanoma
Dysplastic nevi (noncancerous, but unusual-
looking moles)
Previous melanoma
Many nevi (ordinary moles): more than 50
Severe, blistering sunburns
Freckling tendency
Fair skin, light eyes
Excessive use of tanning beds Brought to you by
11. Signs and Symptoms
Melanoma can appear suddenly as a new mole, or
it can develop slowly in or near an existing mole.
In men, melanomas are often found between
the shoulders and hips, or the head and neck
area.
In women, melanoma often develops on the
lower legs as well as between the shoulders and
hips.
It may also appear under the fingernails or
toenails or on the palms or soles.
Brought to you by
12. Signs and Symptoms cont…
A skin growth that increases in size and
looks pearly, translucent, tan, brown,
black, red, pink, or multicolored.
A mole that changes in color or in texture,
becomes irregular in shape, gets larger, or
is bigger than a pencil eraser.
A spot or growth that continues to itch,
hurt, crust, scab, erode, or bleed.Brought to you by
13. Signs and Symptoms cont…
An open sore that lasts for more
than 4 weeks, or heals and then
reopens.
A scaly or crusty bump that is horny,
dry, and rough and may produce a
pricking or tender sensation.
Brought to you by
14. ABCD’s of Melanoma
A
Asymmetry--one half unlike the other half.
B
Border irregular--scalloped or poorly
circumscribed border.
C
Color varied from one area to another; shades of
tan and brown; black; sometimes white, red or blue.
D
Diameter larger than 6mm as a rule (diameter of a
pencil eraser). Brought to you by
16. Melanoma
Early Melanoma is totally
curable. If melanomas of
this type are diagnosed
early minor surgery is all
that is required.
Brought to you by
17. Melanoma
Surface Melanoma- Most
common form of
melanoma. Spreads across
the surface of the skin.
Only when it invades
deeper does it become
dangerous
Brought to you by
18. Melanoma
Nodular Melanoma -The
most dangerous form of
melanoma, arising as a
small lump on pure
melanoma tissue in the
skin. The risk of death
from this melanoma
increases rapidly as the
tumor buries deeper in
the skin.
Brought to you by
19. Stages of Melanoma - Treatment
Stage 0 — Also called melanoma in
situ, this tumor is found only on the
top layer of the epidermis.
Treatment is by surgery. Virtually all
of these cases can be cured.
Brought to you by
20. Stages of Melanoma - Treatment
Stage IA — The tumor is low-risk,
less than .75 mm in thickness, and/or
has not penetrated to the dermis.
The tumor has not spread to the
lymph nodes or distant organs.
Treatment is by surgery.
Brought to you by
21. Stages of Melanoma - Treatment
Stage IIA — The melanoma is
between 1.5 mm and 4 mm and/or has
penetrated the deep dermis.
Treatment is by surgery.
Brought to you by
22. Stages of Melanoma - Treatment
Stage IIB — The tumor is thicker
than 4 mm and/or invades the
subcutaneous fat. Additional tumors
called “satellites” may be found
within 2 centimeters of the original
tumor. Treatment is by surgery.
Brought to you by
23. Stages of Melanoma - Treatment
Stage III — Melanoma has spread
to the nearest lymph node.
Treatment is by surgery. Adjacent
lymph nodes often removed.
Brought to you by
24. Stages of Melanoma - Treatment
Stage IV — The melanoma has
spread to other organs such as the
lung, liver, or brain, or to distant
areas of skin or lymph nodes.
Treatment may include surgery and
chemotherapy
Brought to you by
25. Facts
One person each hour dies from melanoma.
Melanoma afflicts nearly 45,000
Americans yearly.
Affects all age groups and is one of the
most common cancers in young adults
Melanoma diagnosed at an early stage can
usually be cured, but melanoma diagnosed
at a late stage is more likely to spread and
cause death.
The Key is PREVENTION! Brought to you by
26. Ultraviolet Rays
UV-A
Penetrate more deeply into the
skin's layers than UV-B rays. These
rays contribute to premature aging
and wrinkling of the skin, to sunburn,
and to skin cancer.
Brought to you by
27. UV Radiation
UV-B -Stronger than UV-A, are
more intense in summer months, at
higher altitudes, and closer to the
equator.
Most common cause of sunburning,
can contribute to the premature
aging of the skin and can cause
cataracts.
Brought to you by
28. UV Radiation
UV-C
These rays, although the strongest
and most dangerous, are normally
filtered by the ozone layer and do
not reach the Earth.
Brought to you by
29. How much UV reaches me?
Time of Day: UV is greatest
between 10 AM and 3 PM
Brought to you by
30. How much UV reaches me?
Where You Live: UV is strongest at
the equator and gets weaker as you
move towards the Earth's poles.
Altitude: The air is cleaner and
thinner at higher altitudes;
therefore, UV exposure is greater in
the mountains than in the valleys.
Brought to you by
31. Sun Facts
Protecting your skin during the first 18 years of life can
reduce the risk of some types of skin cancer by up to 78%.
You can get a sunburn even on a cloudy day! Up to 80% of
the sun's rays can penetrate light clouds, mist, and fog.
Severe sunburn during the first 15 years of life can double
the risk of skin cancer.
You can get sunburned when you are in the water - Water
reflects an additional 5% of the sun's rays back on you.
Even dry surfaces reflect the sun's rays! Concrete reflects
10% to 12% of the sun's rays.
Brought to you by
32. Prevention
1. UV reflection from sand, water, pavement,
cement and snow doubles the amount of
ultraviolet exposure.
2. Wear a sunscreen with a minimun of 15 SPF,
even on cloudy days.
SPF- Sun Protection Factor
Number= amount of time you can spend in the sun
without getting burned.
Ex No sunscreen- Burn 10 minutes
Ex SPF- 5- Burn time 50 minutes Brought to you by
