What is melanoma?
Cancer starts when cells change and grow out of control. The changed (abnormal) cells
often grow to form a lump or mass called a tumor. Cancer cells can also grow into
(invade) nearby areas. And they can spread to other parts of the body. This is called
Melanoma is a serious type of skin cancer. It starts in skin cells called melanocytes.
These are cells that give skin its color. Melanoma is much less common than other
types of skin cancer that start in other skin cells. But it's more likely to spread
to other parts of the body.
Melanoma can happen anywhere on the skin. It's most often found in areas exposed to
the sun. Men usually get it between the shoulders and the hips. They may also get
it on their head or neck. Women usually get it on their arms and lower legs. Sometimes
melanoma starts in skin that's never exposed to sunlight, like the mouth, genitals,
and anus. It may even start in the eye, under a fingernail or toenail, and in the
nose and sinuses.
Who is at risk for melanoma?
A risk factor is anything that may increase your chance of having a disease. The exact
cause of someone’s cancer may not be known. But risk factors can make it more likely
for a person to have cancer. Some risk factors may not be in your control. But others
may be things you can change.
The most common risk factors for melanoma include:
Greater amount of time spent in the sun
Use of tanning booths or beds and sunlamps
Many moles or abnormal ones
Fair skin, blue eyes, freckles, or light hair
Family history of melanoma
Certain inherited gene changes and conditions, like xeroderma pigmentosum, Li-Fraumeni
syndrome, and hereditary breast and ovarian cancer syndromes
Past history of skin cancer (any kind)
Weakened immune system
Talk with your healthcare provider about your risk factors for melanoma and what you
can do about them.
Can melanoma be prevented?
There is no sure way to prevent melanoma, but there are things you can do that may
help lower your risk for it, such as:
Wearing broad-spectrum sunscreen with SPF 30 or higher
Not using tanning booths or beds and sunlamps
Practicing sun safety. Limit time in the sun when UV light is strongest – between
10 a.m. and 4 p.m.
Wearing sunglasses that have 100% UVA/UVB protection
Wearing clothing to shade your face and cover your body
Doing skin checkups often
Regular skin self-exams may help you find skin cancer early, when it’s smaller and
easier to treat. Become familiar with the way your skin and moles look. Talk with
your healthcare provider about any bumps, spots, or other marks on your skin.
What are the symptoms of melanoma?
The first symptom of melanoma is often a change in a mole or the appearance of a new
mole. The ABCDE rule can help you tell a normal mole from one that might be melanoma.
The rule is:
Asymmetry. One half of the mole does not match the other half.
Border irregularity. The edges of the mole are ragged or irregular.
Color. The mole has different colors in it. It may be tan, brown, black, red, or other colors.
Or it may have areas that appear to have lost color.
Diameter. The mole is bigger than 6 mm or ¼ inch across, about the size of a pencil eraser.
But some melanomas can be smaller.
Evolving. A mole changes in size, shape, or color.
Other symptoms that may be melanoma include:
A mole that hurts, itches, or is sore
A mole that oozes, bleeds, or becomes crusty
A mole that looks different from your other moles
A sore that doesn't heal
A mole or sore that becomes red or swells at its edges or beyond
Many of these may be caused by other health problems. Still, it's important to see
a healthcare provider if you have these symptoms. Only a healthcare provider can tell
if you have cancer.
How is melanoma diagnosed?
If your healthcare provider thinks you may have melanoma, you'll need certain exams
and tests. You'll be asked about your health history, your symptoms, risk factors,
and family history of disease. A physical exam and skin exam will be done. You may
also have a biopsy.
A biopsy is the only way to confirm cancer. Tiny pieces of the changed mole or skin
are removed and sent to a lab. Then they're tested for cancer cells. Your results
should come back in about 1 week.
After a diagnosis of melanoma, you'll need more tests. These help your healthcare
providers learn more about your overall health and the cancer. They're used to find
out the stage of the cancer. The stage is how much cancer there is and how far it
has spread (metastasized) in your body. It's one of the most important things to know
when deciding how to treat the cancer.
Once your cancer is staged, your provider will talk with you about what the stage
means for your treatment. Be sure to ask your provider to explain the details of your
cancer to you in a way you can understand.
How is melanoma treated?
Your treatment choices depend on the size, place, and stage of your melanoma. The
goal of treatment may be to cure you, control the cancer, or help ease problems caused
by cancer. Talk with your healthcare team about your treatment choices, the goals
of treatment, and what the risks and side effects may be. Other things to think about
are if the cancer can be removed with surgery, how your body will look after treatment,
and your overall health.
Types of treatment for cancer are either local or systemic. Local treatments remove,
destroy, or control cancer cells in one area. Surgery and radiation are local treatments.
Surgery is the most common way to treat melanoma. Systemic treatment is used to destroy
or control cancer cells that may have traveled around your body. When taken by pill
or injection, chemotherapy and targeted therapy are systemic treatments. You get just
one treatment or a combination of treatments.
Melanoma may be treated with:
Talk about your concerns with your provider before making a decision.
What are treatment side effects?
Surgery to remove your melanoma will always result in a scar. Talk with your healthcare
provider about the size and type of scar you may end up with.
Cancer treatment, such as chemotherapy and radiation, can damage normal cells. This
can cause side effects like hair loss, mouth sores, and vomiting.
Talk with your provider about side effects linked with your treatment. There are often
ways to manage them. There may be things you can do and medicines you can take to
help prevent or control many treatment side effects.
Coping with melanoma
Many people feel worried, depressed, and stressed when dealing with cancer. Getting
treatment for cancer can be tough on the mind and body. Keep talking with your healthcare
team about any problems or concerns you may have. Work together to ease the effect
of cancer and its symptoms on your daily life.
Here are tips:
Talk with your family or friends.
Ask your healthcare team or social worker for help.
Speak with a counselor.
Talk with a spiritual advisor, such as a minister or rabbi.

Cancer treatment is also hard on the body. To help yourself stay healthier, try to:
Eat a healthy diet with as many protein foods as possible.
Drink plenty of water, fruit juices, and other liquids.
Keep physically active.
Rest as much as needed.
Talk with your healthcare team about ways to manage treatment side effects.
Take your medicines as directed by your team.
