Skin Cancer
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).
Basal cell carcinoma
may come in many forms. It often begins as a small, pearly nodule.
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.
Squamous cell carcinoma
may begin as a red, scaly patch, a group of crusted nodules, or a sore that doesn't
heal.
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.
Malignant melanoma is often asymmetrical,
with blurred or ragged edges and mottled colors.
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.
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.
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. The risks of
surgery are generally low.
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 treatments 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 should 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.
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.
