Skin moles are not an uncommon condition affecting the skin of a person. Basically skin moles can be seen or start appearing during the first twenty years of the person’s life. It is quite unusual and extremely rare for a kid to develop moles in the womb and be born with it. Skin moles can be and are classified as lesions of the skin and they contain different cells as well. These cells are called as nevus cells.
The formation of the moles can begin in the inner layers of the skin as well as the outer layer of the skin. Skin moles can also be a sign of skin cancer (melanoma). Both the kinds of moles, the ones formed in the top layer of the skin to the ones which are formed in the deeper layers of the skin have one factor in common and that is melanocyte.
Moles stand out easily because of two basic reasons. The first reason is that they are malformations of the skin and cells which can be distinguished by the naked eye. The second reason is that the moles have a high concentration of melanin as well. Melanin is what causes the moles to take up a darker shade of color when compared to the color of the surrounding skin. The occurrence of moles on specific parts of the body are based on many factors like ethnicity, race etc.
Though one can be sure of moles only after they can be seen but some symptoms can be treated as a give away. A coarse patch of raised skin, even if a little bit is a sign of a mole. This patch of skin will also be considerably darker in color.
On the whole there are basically four types of moles for a person to look out for. These types are skin tags, flat moles, and benign moles and raised moles. There might also be a few hairs growing out of the patch of skin identified as a mole.
Causes Behind Appearance of Skin Moles
The appearance of atypical skin moles can be blamed on heredity as it has been scientifically been proven that this condition is passed on from one generation to another. This syndrome is radical as people end up with a large number of moles on their body (nearly a 100 or even more). The higher the number of moles on a person’s bodies the higher the risk of melanoma or skin cancer.
If the moles are classified as dysplastic nevi then the risk of cancer increases even further as this type of moles are more likely to turn in to a cause for cancer. People have a misconception that only moles can turn cancerous but it is untrue.
Cancer can create new malformations on the skin which might not be present before but might be a new growth which is of a cancerous nature. Thus it is highly advisable for people with a high number of moles on their skin to visit the doctor for regular check ups in order to avoid and sudden surprises.
Even exposure to sunlight is said to play a role in the formation of moles but there is no solid, concrete proof to this effect. A lot of research needs to be carried out to understand the role of sunlight and its effect on the skin but it is certain that sunlight does play a role. The ultraviolet rays emitted by the sun can have an adverse effect on the skin which might result in the formation of cancerous moles.
