Skin Moles

Skin moles

     In the summer time we all want to take advantage of the sun and get a great tan. Unfortunately, excessive sun exposure has a number of risks, especially for the skin and the cardiovascular system. Not only people that are at the beach may exhibit excessive sunlight, but also the ones who have errands to run in the middle of the day, those who practice outdoor sports, workers on construction sites, farmers etc..

     About the health risks of the overexposure to sun we will discuss about the pathology of which incidence has become quite high: malign melanoma or skin cancer. Generally, it develops on the basis of skin moles (mole), but sometimes a new pigmentation may appear new, which has a rapid growth rate.

What are skin moles?

     Skin moles or nerves appear as small spots, with pigmentation (brown, purple, color, etc.). The skin moles are produced by certain cells in the skin that produce pigment. The form of the skin moles is varied and can be round or irregular-cut edges, they can appear in the form of plain or rogues growths, pigmented or not, or irregular edges, etc. They may have a lot of nuances.

How do skin moles appear?

     Skin moles appear after birth and still continue to occur until after puberty. After this age the rate of occurrence is very low. Factors that favor the appearance of skin moles are represented by sun exposure (occurring on skin areas that are most exposed: shoulders, face, hands, etc..). The influence of genetics, gender (women generally have more moles than men) of color (those with very white skin have more moles, freckles).

     Skin moles may change over time and expand in size or on the contrary, reducing themselves to extinction. Usually people "possessing" these changes are not aware of them, especially because we were not educated in terms of tangible auto examination (weekly a person must look in the mirror and examine his whole body, and women must auto examine their breasts).

When are skin moles carcinogenic?

     Skin moles are generally harmless, but in some cases they can turn into skin cancer, specifically in malignant melanoma. This is the most severe type of skin cancer and it is most often caused by short but intense exposure to the sunlight, for example a one week holiday at sea. These rare exposures to sunlight, short and intense show a high risk for skin cancer.

     Malignant melanoma can occur anywhere on the body, a pre-existing mole or skin in an area which previously had been healthy. It appears as often a mole whose dimensions are expanding rapidly, the "pigmented stain" reaches diameters of the order of centimeters. Usually shows more colors than the normal usual moles (normal nevi has at most two shades), the pigment stain is annoying, it causes itches, may be ulcerated, hemorrhagic, it shows a surface without having been traumatized, has irregular edges, can cause inflammation, infection, etc..

     It is not mandatory that all these features will appear simultaneously, but the appearance of one feature of abnormality of the ones above can raise suspicion of malignant transformation (melanoma).

How to prevent the malignant transformation of skin moles?

     First of all the protective measures will be taken with regard to sun exposure: avoid the noon sun exposure, use sunscreen creams with big factor, wear long sleeve clothes etc.

     About skin moles, their evolution will be observed regularly. If the doctor notices a skin mole with slight atypical characters, a photo will be made (to make further comparisons) and it will check it periodically. Irregular shapes nevi in several colors that seem to grow quickly, which are itchy, inflamed or the new ones will be observed.

     Even if your family doctor will not call you to a control for performing a complete examination, it is important to inform you about these diseases that you are exposed to, what to watch in terms of personal health.
