Most of the more than 1 million cases of non-melanoma skin
cancer diagnosed yearly in the United States are considered to be
sun-related. Melanoma, the most serious type of skin cancer, will
account for about 68,720 cases of skin cancer in 2009 and most (about
8,650) of the 11,590 deaths due to skin cancer each year.

The 5-year survival rates represent
persons who are living 5 years after diagnosis, whether disease-free,
in remission, or under treatment. They do not imply that 5-year
survivors have been permanently cured of cancer. Localized cancer
represents cancer that, at the time of diagnosis, had not spread to
additional sites within the body. Typically the earlier a cancer is
detected and diagnosed, the more successful the treatment, thus
enhancing the survival rate.
For localized melanoma, the 5-year survival rate is 99%;
survival rates for regional and distant stage diseases are 65% and 16%,
respectively. About 80% of melanomas are diagnosed at a localized
stage.
Frequently Asked Questions
What is the skin?
The skin is the largest organ of the body. It covers the internal
organs and protects them from injury; serves as a barrier between
germs, such as bacteria, and internal organs; and prevents the loss of
too much water and other fluids. The skin regulates body temperature
and helps the body get rid of excess water and salts. Certain cells in
the skin communicate with the brain and allow for temperature, touch,
and pain sensations.
What is
non-melanoma (basal or squamous cell) skin cancer? Most
skin cancers are classified as non-melanoma, usually starting in either
basal cells or squamous cells. These cells are located at the base of
the outer layer of the skin or cover the internal and external surfaces
of the body.
Most non-melanoma skin cancers develop on sun-exposed areas of
the body, like the face, ear, neck, lips, and the backs of the hands.
Depending on the type, they can be fast or slow growing, but they
rarely spread to other parts of the body.
What is melanoma
skin cancer? Melanoma is a cancer that begins in the
melanocytes -- the cells that produce the skin coloring or pigment
known as melanin. Melanin helps protect the deeper layers of the skin
from the harmful effects of the sun.
Melanoma is almost always curable when it is detected in its
early stages. Although melanoma accounts for only a small percentage of
skin cancer, it is far more dangerous than other skin cancers and
causes most skin cancer deaths.
How many people
are affected by skin cancer? Skin cancer is the most
common of all cancers. It accounts for nearly half of all cancers in
the United States. More than 1 million cases of non-melanoma skin
cancer are found in this country each year. The American Cancer Society
estimates that about 68,720 new melanomas will be diagnosed in the
United States during 2009.
Who survives
skin cancer? For basal cell or squamous cell cancers, a
cure is highly likely if detected and treated early. Melanoma, even
though it can spread to other body parts quickly, is also highly
curable if detected early and treated properly. The 5-year relative
survival rate for patients with melanoma is 91%. For localized
melanoma, the 5-year survival rate is 99%; survival rates for regional
and distant stage diseases are 65% and 16% respectively. About 80% of
melanomas are diagnosed at a localized stage.
How many people
will die from skin cancer? The American Cancer Society
estimates there will be about 11,590 deaths from skin cancer in 2009:
8,650 from melanoma and 2,940 from other skin cancers.
What are the
risk factors for skin cancer? Risk factors for
non-melanoma and melanoma skin cancers include:
- unprotected and/or excessive exposure to ultraviolet (UV)
radiation
- fair complexion
- occupational exposures to coal tar, pitch, creosote,
arsenic compounds, or radium
- family history
- multiple or atypical moles
- severe sunburns as a child
What are the
signs and symptoms of skin cancer? Skin cancer can be
found early, and both doctors and patients play important roles in
finding skin cancer. If you have any of the following symptoms, tell
your doctor.
- any change on the skin, especially in the size or color of
a mole or other darkly pigmented growth or spot, or a new growth
- scaliness, oozing, bleeding, or change in the appearance of
a bump or nodule
- the spread of pigmentation beyond its border such as dark
coloring that spreads past the edge of a mole or mark
- a change in sensation, itchiness, tenderness, or pain
Can skin cancer be prevented? The best ways to lower the risk
of non-melanoma skin cancer are to avoid intense sunlight for long
periods of time and to practice sun safety. You can continue to
exercise and enjoy the outdoors while practicing sun safety at the same
time. Here are some ways you can do this:
- Avoid the sun between 10 a.m. and 4 p.m.
- Seek shade: Look for shade, especially in the middle of the
day when the sun's rays are strongest. Practice the shadow rule and
teach it to children. If your shadow is shorter than you, the
sun’s rays are at their strongest.
- Slip on a shirt: Cover up with protective clothing to guard
as much skin as possible when you are out in the sun. Choose
comfortable clothes made of tightly woven fabrics that you cannot see
through when held up to a light.
- Slop on sunscreen: Use sunscreen and lip balm with a sun
protection factor (SPF) of 15 or higher. Apply a generous amount of
sunscreen (about a palmful) and reapply after swimming, toweling dry,
or perspiring. Use sunscreen even on hazy or overcast days.
- Slap on a hat: Cover your head with a wide-brimmed hat,
shading your face, ears, and neck. If you choose a baseball cap,
remember to protect your ears and neck with sunscreen.
- Wrap on sunglasses: Wear sunglasses with 99% to 100% UV
absorption to provide optimal protection for the eyes and the
surrounding skin.
- Follow these practices to protect your skin even on cloudy
or overcast days. UV rays travel through clouds.
- Avoid other sources of UV light. Tanning beds and sun lamps
are dangerous because they can damage your skin.
What Is the American Cancer Society Doing
About Skin Cancer?
- Education: The
Society delivers health information to the public, so that individuals
can make informed personal decisions. Examples include: Printed
materials, media coverage, community-based outreach programs, and free,
nationwide services such as www.cancer.org
and 1-800-227-2345. The American Cancer Society also began its Sun Safe
Community initiative in December 2000 to help prevent skin cancer. This
community-based, multi-component effort consists of prevention programs
at schools, childcare centers, primary care offices, and beach and
recreation areas.
- Advocacy:
With the help of grassroots volunteers in communities across the
country, the Society advocates with lawmakers at both the state and
federal levels to ensure responsible health policies are enacted and to
increase funding for research and testing and treatment coverage.
- Service: The
Society works to improve quality of life for people living with cancer
through a variety of support services and programs helping patients and
families cope with the disease.
- The Society also has collaborations with many nationwide
organizations to promote skin cancer prevention, education, and
sun-safe policies.
