3Basal Cell Carcinoma the most common type - up
to 90 of all skin cancers are this.
4This is another basal cell carcinoma. They
typically start as a shiny bump, then slowly grow
and form disfiguring masses. They seldom
metastasize. Removal is done surgically, and
only require radiation in tough to treat cases.
5When left untreated, basal cell carcinomas can
cause great disfigurement. Surgical removal will
leave large depressions in the skins surface.
6The dark area in the center of this circle is a
squamous cell carcinoma. After surgical
removal, this patient will receive radiation
treatment. Between 1500 and 2000 people die from
this type of cancer each year.
7This girl has a squamous cell carcinoma. People
with high melanin content are not immune to skin
cancers!
8This is an example of melanoma or malignant
melanoma. This is the most dangerous form, and
also the most rare.
9The ABCD Rule of Melanoma
- A Asymetry one half of the mole does not
match the other - B Border Irregularity the edges of the mole
are uneven, notched or blurred - C Color the pigment is not even. Cancerous
moles may have several colors in one mole (blue,
red, brown or black) - D diameter - watch moles the size of a pencil
eraser or larger for changes.
10This melanoma grew under this mans fingernail.
The nail has been removed to facilitate removal
of the tumor.
11 The large brown mass on the side of this womans
nose is a malignant melanoma.
12This is the same woman. Her melanoma has been
removed. If you look closely, you can see the
depression where the tumor once was located.
13 This is a further close-up of the womans scar.
14Doctors found that her cancer had spread, so she
underwent chemotherapy to try to obliterate all
of the cancerous cells. The differences in the
womans appearance are side effects of the
chemotherapy.
15This woman has a small melanoma on her neck.
16The peeling that you see on this womans legs
is the result of melanoma that metastasized
through her lymph system. She began
chemotherapy treatments soon after this photo.
17This is one of several melanomas on this mans
face.
18This is another melanoma on this girls leg.
Notice how large and irregular it is.
19With this close-up, the asymmetry is easy to see.
20Although it looks like a bruise, this man has an
advanced melanoma on his eyelid.

22This woman has many melanoma tumors on her back.
She is 49 years old.
23Again, a close up. If youre not in the habit of
checking your back, have a family member do it
for you yearly.
24Its hard to see what is wrong with this woman.
There is a melanoma on the left side of her nose
in this picture. Although its not dark, the
tumor is still melanoma.
25The womans nose had to be removed because the
cancer was so advanced. The pen marks are guides
for radiation, while the mouth cork is to keep
her airway open.

30This is not a color enhanced photo. This woman
did not read the warnings on her medicine. She
went to the tanning bed while taking
tetracycline. This antibiotic amplifies the
effects of UV light.
31Immunological factors and UV light normal
epidermal Langerhans cells on the left there
are fewer cells on the right after being treated
with UV light.
