Myth number 1. Moles are weak skin places
Not weak places, but rather its defect. Norma pigment cells
Melanocytes are between two layers of the skin - epidermis and dermis.
When they move from the depth of the fabric to the skin surface and form
clusters, a pigment spot arises - Nesus, or simply mole.
On average, when a person occurs, a person can have up to 10 moles. WITH
Their strength of them becomes more. As a rule, intensively they are
appear from 17 to 27 years. Initially, neutres look like microscopic
Spot 1-3 mm in diameter and gradually reach 1.5-5 cm. By the way, far
not any mole is such. Freckles often take
(lentigo).
Myth number 2. The most dangerous - large convex moles
To some extent, this is true: medium in size and
Large moles require increased attention. However, reborn in
Malignant can and very small (only 1.5 cm) moles - so
called dysplastic nevi, predecessor
and melanoma. They can
be both convex and flat.
A non-specialist computing a dangerous birthplace is very difficult, but some
General signs are. As a rule, the dysplastic Neva has uneven
contours or uneven coloring (brown with enlightened
Sections, with islets of dark or white color). In women dangerous
Moles are most often localized on the legs, in men - on the back.
Myth number 3. Melanoma - hereditary disease and sadness of fate
With dangerous moles, we are already born. Perennial medical
observations show: 2/3 cases of melanoma - not congenital, and
Acquired origin.
The rebirth process of the nevus stretches from five to ten years. And in this
- The greatest cunning of melanoma. Man can live with mine
slow motion on the body and not to know that his life is in danger.
True, the factor of heredity is not worth discount. There is
Such a concept is a syndrome of multiple dysplastic nonsense (this
When literally the whole body of a person is covered by moles). From point of view
Oncologists, such people should be extremely careful: a chance to earn
meanoma is significantly higher than others.
Myth number 4. The sun is guilty
Not always. There are cases when Melanoma arose in people who never went out of northern latitudes and not sunbathe.
Although, of course, excessive stay in the sun in the occurrence
melanoma - the factor is important. After all, the tan is nothing more than
Natural Skin Protection from the Sun. Under the influence of ultraviolet
The genetic code of the components of the neust melanocytes is affected, violated
The process of their dying. As a result «Keeping» Cells are reborn,
that in the end can be tumor process.
Myth number 5. To earn melanoma, you need to burn ahead several times
Such the theory is not devoid of grounds. Especially if for the first time the skin burn
man received in childhood. Research of recent years indicate
that every sunny burn obtained in gentle age in
several times increases the risk of melanoma in mature years.
Most of the representatives of I and II phototypes are risky - Beloke,
Red-haired and blue-eyed. Going to the south, they need to be especially
Careful. Fortunately, the overwhelming majority of Russians belong to
Third Phototipu with Good Adaptation Opportunities Skin. But im
Farming on the sun is not worth it, especially if the sun is southern and active.
Going on vacation to Canara or Maldives, people, not
adapted to so intense sunny mode, risk.
No wonder for the White Population of Australia, Africa, Central and South
America Melanoma has become a real national disaster.
Myth number 6. The main factors of the development of melanoma - trauma «
Nehorish» moles
Do not touch her and she is not «Ubusit». One of the most common and
annoying misconceptions. The earlier you remove the potentially dangerous
the birthplace, the less chance that the process of its rebirth will go too
long away. Thanks to such tactics in America and Australia, where
Recent decades have broken up a real skin cancer epidemic, percentage
mortality from melanoma went to the decline.
To random injuries of municipalities that are so afraid of overwhelming
Most people, doctors relate rather as a good, rather than
misfortune. They help to identify the future melanoma, pay attention to it -
and neutralize.
Although, of course, it is better to identify «enemy» More harmless means.
It is only necessary to regularly study your body, carefully tracking everything
Change. If among your moles there are those that cause
Anxiety, do not pull, run to the doctor!
