Melanoma Skin Cancer is started in the cells that produce
pigments. These cells are called Melanocytes. The Melanin that is the
cause of skin, eyes and hair colour is the result of these cells.
According to the NCI (National Institute of Cancer), there are over
68,000 new cases and near 9,000 deaths of Melanoma Skin Cancer each year
in US.
The first sign of melanoma is normally a change in shape
or colour and maybe size of a currently existed mole. You should see
your doctor if you see a sudden or continuous change in the shape and
size or colour of a mole. Sometimes melanoma appears on your skin as a
new mole.
It's very easy to memorize what you look for. There are five parameters involved that we can refer to as "ABCDE" that are:
1. Asymmetry: when the shape of one half of the mole is not the same as the shape of the other half.
2. Border: when the pigment is spread into the nearby skin so the borders and edges are normally blurred and ragged.
3.
Colour: it is normally uneven. Normally there are brown or black shades
or some areas are white, gray and red or sometimes pink.
4. Diameter: the size can be very different but normally the melanomas are larger than 6 millimetres or ¼ inch.
5. Evolving: when the mole has changed during the past few weeks or months.
But
have in mind that not all the melanomas show all of the above mentioned
features. Sometimes the changes are only in one or two of the ABCDE.
There are some other warning signs and symptoms:
a. When you see a new bump
b. When colour is spread into the nearby skin areas
c. When you see a redness or swelling that is beyond the mole itself
d. When you feel pain
e. When you feel itching
f. When the mole bleeds
g. Sometimes oozing
h. Tenderness can be a sign as well
i. And scaly appearance
When
the melanoma is more advanced, the texture of the mole may change. The
skin becomes harder and the surface of the skin sometimes breaks down
and scraped. Sometimes even bleeding has been reported and it may get
itchy or painful.
Your doctor is definitely a person who can help you. Make sure if there is anything that bothers you, go and see your doctor.
What causes Melanoma Skin Cancer
The
most dangerous cause of Melanoma Skin Cancer is the exposure to
sunlight ultra violet rays. Melanocytes make more melanin under the sun
light. That's why our skin is tanned under the sun. Scientist believe
that enough exposure to UV radiation can hurt the DNA in melanocytes and
causes them to grow more than normal and out of control.
It's
good to know that Melanoma Skin Cancer happens more often in fair skin
people than brown and black skin people. Fair or white skin people have
less melanocyte cells in their skin hence more dangerous the UV ray is
for them.
Doctors believe that Melanoma Skin Cancer is related not
only to exposure to sun, but genetics plays a big role in this cancer.
Because Melanoma Tumors can occur in the areas of the body that are not
normally exposed to the sun. So people with family history of melanoma
are more likely to develop the cancer. According to researches done by
NCI (National Cancer Institute) One out of ten people diagnosed with
melanoma have a family member who was previously diagnosed with the
disease.
How to treat Melanoma Skin Cancer
Like most of the
diseases and cancers, there is a good chance of good prognosis when the
cancer is caught early. If the brown or black lesion has not spread
beyond the skin surface, a simple surgery may be enough to cure the
cancer.
But in more advanced cancer, the one that melanoma has
spread to other parts of body, it is difficult to treat. According to
NCI the chances of 5-year survival rate are:
1. 98% localised melanoma. 84% of melanoma cases are diagnosed at this stage
2. 62% if melanoma is spread under the skin to nearby lymph nodes
3. 16% if it spreads to distant parts of the body
In the last two cases doctors use Chemotherapy, radiation or biological therapy to treat the cancer.
How to prevent Melanoma Skin Cancer
It
is not very easy to treat this cancer and it can take a lifelong, but
it only takes some very simple precautions to decrease the risk.
The
first and maybe the most important factor is avoiding tanning beds.
Wearing sunscreens with SPF (Sun Protection Factor) of above 15 is
another simple step. Wearing hats, visors and tightly woven clothing is
very good to block the sunlight UV ray. And the last one is staying out
of the sun during 10 am and 4 pm when the sunlight is very strong and UV
level is at the highest.
