Skin
Cancer - And Your Plastic Surgeon
Skin cancer is the most common form of cancer in the United
States. More than 500,000 new cases are reported each
year-and the incidence is rising faster than any other
type of cancer. While skin cancers can be found on any
part of the body, about 80 percent appear on the face,
head, or neck, where they can be disfiguring as well as
dangerous.
The
purpose of this brochure is to educate you about the different
types of skin cancer, their causes, and preventive measures
you can take; to help you know when to consult a doctor;
and to explain the role of the plastic surgeon in the
diagnosis and treatment of skin cancer and other skin
growths.
Who
gets skin cancer ...and why
The primary cause of skin cancer is ultraviolet radiation
-most often from the sun, but also from artificial sources
like sunlamps and tanning booths. In fact, researchers
believe that our quest for the perfect tan, an increase
in outdoor activities, and perhaps the thinning of the
earth's protective ozone layer are behind the alarming
rise we're now seeing in skin cancers.
Anyone
can get skin cancer-no matter what your skin type, race
or age, no matter where you live or what you do. But your
risk is greater if...
Your skin is fair and freckles easily.
You have light-colored hair and eyes.
You have a large number of moles, or moles of unusual
size or shape.
You have a family history of skin cancer or a personal
history of blistering sunburn.
You spend a lot of time working or playing outdoors.
You live closer to the equator, at a higher altitude,
or in any place that gets intense, year-round sunshine.
You received therapeutic radiation treatments for adolescent
acne.
Types
of skin cancer
By far the most common type of skin cancer is basal cell
carcinoma. Fortunately, it's also the least dangerous
kind--it tends to grow slowly, and rarely spreads beyond
its original site. Though basal cell carcinoma is seldom
life-threatening, if left untreated it can grow deep beneath
the skin and into the underlying tissue and bone, causing
serious damage (particularly if it's located near the
eye).
Squamous
cell carcinoma is the next most common kind of skin cancer,
frequently appearing on the lips, face, or ears. It sometimes
spreads to distant sites, including lymph nodes and internal
organs. Squamous cell carcinoma can become life threatening
if it's not treated.
A
third form of skin cancer, malignant melanoma, is the
least common, but its incidence is increasing rapidly,
especially in the Sunbelt states. Malignant melanoma is
also the most dangerous type of skin cancer. If discovered
early enough, it can be completely cured. If it's not
treated quickly, however, malignant melanoma may spread
throughout the body and is often deadly.
Other
skin growths you should know about
Two other common types of skin growths are moles and keratoses.
Moles
are clusters of heavily pigmented skin cells, either flat
or raised above the skin surface. While most pose no danger,
some-particularly large moles present at birth, or those
with mottled colors and poorly defined borders-may develop
into malignant melanoma. Moles are frequently removed
for cosmetic reasons, or because they're constantly irritated
by clothing or jewelry (which can sometimes cause pre-cancerous
changes).
Solar
or actinic keratoses are rough, red or brown, scaly patches
on the skin. They are usually found on areas exposed to
the sun, and sometimes develop into squamous cell cancer.
Recognizing
skin cancer
Basal and squamous cell carcinomas can vary widely in
appearance. The cancer may begin as small, white or pink
nodule or bumps; it can be smooth and shiny, waxy, or
pitted on the surface. Or it might appear as a red spot
that's rough, dry, or scaly...a firm, red lump that may
form a crust...a crusted group of nodules...a sore that
bleeds or doesn't heal after two to four weeks...or a
white patch that looks like scar tissue.
Malignant
melanoma is usually signaled by a change in the size,
shape, or color of an existing mole, or as a new growth
on normal skin. Watch for the "ABCD" warning
signs of melanoma: Asymmetry-a growth with unmatched halves;
Border irregularity-ragged or blurred edges; Color-a mottled
appearance, with shades of tan, brown, and black, sometimes
mixed with red, white, or blue; and Diameter- a growth
more than 6 millimeters across (about the size of a pencil
eraser), or any unusual increase in size.
If
all these variables sound confusing, the most important
thing to remember is this: Get to know your skin and examine
it regularly, from the top of your head to the soles of
your feet. (Don't forget your back.) If you notice any
unusual changes on any part of your body, have a doctor
check it out.
Basal cell carcinoma may come in
many forms. It often begins as a small,
pearly nodule.
Squamous cell carsinoma may begin as
a red, scaly patch, a group of crusted
nodules, or a sore that doesn't heal.
Malignant melanoma is often
asymmetrical, with blurred or ragged
edges and mottled colors.
Choosing
a doctor
If you're concerned about skin cancer, your family physician
is a good place to start. He or she should examine your
skin at your annual physical, and can refer you to a specialist
if necessary.
If
you notice an unusual growth yourself, consult a plastic
surgeon or a dermatologist. Both are skilled at diagnosing
and treating skin cancer and other skin growths. A plastic
surgeon can surgically remove the growth in a manner that
maintains function and offers the most pleasing final
appearance- a consideration that may be especially important
if the cancer is in a highly visible area. If a treatment
other than surgical excision is called for, the plastic
surgeon can refer you to the appropriate specialist.
Diagnosis
and treatment
Skin cancer is diagnosed by removing all or part of the
growth and examining its cells under a microscope. It
can be treated by a number of methods, depending on the
type of cancer, its stage of growth, and its location
on your body.
Small skin cancers can often be excised
quickly and easily in the physician's office.
Most
skin cancers are removed surgically, by a plastic surgeon
or a dermatologist. If the cancer is small, the procedure
can be done quickly and easily, in an outpatient facility
or the physician's office, using local anesthesia. The
procedure may be a simple excision, which usually leaves
a thin, barely visible scar. Or curettage and desiccation
may be performed. In this procedure the cancer is scraped
out with an electric current to control bleeding and kill
any remaining cancer cells. This leaves a slightly larger,
white scar. In either case, the risks of the surgery are
low.
Simple excision usually leaves a thin
barely visible scar.
If
the cancer is large, however, or if it has spread to the
lymph glands or elsewhere in the body, major surgery may
be required. Other possible treat- ments for skin cancer
include cryosurgery (freezing the cancer cells), radiation
therapy (using x-rays), topical chemotherapy (anti-cancer
drugs applied to the skin), and Mohs surgery, a special
procedure in which the cancer is shaved off one layer
at a time. (Mohs surgery is performed only by specially
trained physicians and often requires a reconstructive
procedure as follow-up.)
Discussing
your options and concerns
All of the treatments mentioned above, when chosen carefully
and appropriately, have good cure rates for most basal
cell and squamous cell cancers -and even for malignant
melanoma, if it's caught very early, before it's had a
chance to spread.
You
òld discuss these choices thoroughly with your
doctor before beginning treatment. Find out which options
are available to you...how effective they're likely to
be for your particular cancer...the possible risks and
side effects...who can best perform them...and the cosmetic
and functional results you can expect. If you have any
doubts about the outcome, get a second opinion from a
plastic surgeon before you begin treatment.
A
word about reconstruction
The different techniques used in treating skin cancers
can be life saving, but they may leave a patient with
less than pleasing cosmetic or functional results. Depending
on the location and severity of the cancer, the consequences
may range from a small but unsightly scar to permanent
changes in facial structures such as your nose, ear, or
lip.
In
such cases, no matter who performs the initial treatment,
the plastic surgeon can be an important part of the treatment
team. Reconstructive techniques- ranging from a simple
scar revision to a complex transfer of tissue flaps from
elsewhere on the body-can often repair damaged tissue,
rebuild body parts, and restore most patients to acceptable
appearance and function.
A
bone/soft tissue flap is used to
reconstruct the nose following skin
cancer excision.
The incision lines of the flap are
hidden within the natural creases of
the nose and face.
Preventing
a recurrence
After you've been treated for skin cancer, your doctor
should schedule regular follow-up visits to make sure
the cancer hasn't recurred.
Your
physician, however, can't prevent a recurrence. It's up
to you to reduce your risks by changing old habits and
developing new ones. (These preventive measures apply
to people who have not had skin cancer as well.)
Avoid prolonged exposure to the sun, especially between
10 a.m. And 2 p.m. and during the summer months. Remember,
ultraviolet rays pass right through water and clouds,
and reflect off sand and snow.
When you do go out for an extended period of time, wear
protective clothing such as wide brimmed hats and long
sleeves.
On any exposed skin, use a sunscreen with an SPF (sun
protection factor) of at least 15. Reapply it frequently,
especially after you've been swimming or sweating.
Finally, examine your skin regularly. If you find anything
suspicious, consult a plastic surgeon or a dermatologist
as soon as possible.
