On body of each there are several or even dozens of moles. In most cases, these moles lie obediently, and for most part spoil appearance. But if mole is in a place where it should not be, and suddenly looks different, it's time to pay attention to it.
Because even a small mole can cause cancer!
Pigmented nevus, scientifically called melanocytic nevus, also known as nevus cell nevus, is a benign hyperplasia composed of nevus cells. Nevus cells belong to type of melanocytes, but their structure differs from latter. Nevus cells are usually located at junction of epidermis and dermis of skin, or dermis.
With age, nevus cells tend to grow deep into dermis, reaching even subcutaneous tissue, and color also changes.
Moles that most people think of are basically divided into following three situations:
1. Intradermal nevus (meat nevus)
Most of "matchmaker moles" we often talk about are of this type, which exist in dermis and are more common in middle-aged and older people.
However, although this type of mole has a great impact on appearance, risk of malignant transformation is least.
2. Nodular nevus
In other words, nevus cells accumulate at junction of epidermis and dermis. Most of them are relatively flat, and some protrude slightly from skin, with a smooth, hairless surface.
But it should be noted that if it is "stimulated" too much, it can turn into a "tumor".
3. Mixed moles
Representative of Buddhist world, mixed in epidermis and dermis, slightly above skin, and risk of malignant transformation is in middle of these three types of moles.
In medicine, "nevus" is also called melanoma, and it is "nevus" that you need to pay attention to.
When safe, it is actually a benign tumor, also known as a melanocytic nevus. It often appears before us in various forms, such as smooth, papillary, slightly protruding, hairy, hairless, black, reddish brown, and so on.
What conditions predispose to cancer?
Normally, melanocytes are evenly distributed in our skin.
If you suddenly encounter an obstacle, melanocytes will become more and more, and they will gradually "stick together" and turn into a melanoma, which is a benign melanocytoma.
However, certain factors, such as ultraviolet radiation, friction, genetics, and other factors, increase likelihood that these "moles" will become cancerous, turning "melanoma" into "melanoma."
So how do you know if a mole on your body is dangerous or not?
In general, you should always pay attention to moles in these 3 places!
1. Waist belt area
The lumbar region of waist and abdomen is often subjected to friction, which increases risk of mole cancer.
2. Moles on palms and nails
Moles on palms and nails are also places of increased risk for melanoma.
3. Moles on soles of feet
This needs special attention, as long-term friction while walking is more likely to cause cancer.
However, we must also learn to accept moles on our body, each mole is our unique imprint.
As long as they're lying around, they're fine.
