Nevi pigmentation also known as moles are, in medical terms, agglomerations of pigment cells, which can occur anywhere on the body. Most moles - adult females may have up to 40 - are harmless. However, in some cases, some moles may become cancerous.
The risk of melanoma - the most dangerous type of skin cancer - increases every year, at this time there are a minimum of 100 000 cases of malignant melanoma reported every year worldwide.
Removal of moles may have a medical indication as motivation, physical discomfort (caused by friction from clothing or in areas where their presence can be easily traumatized) or simply an aesthetical reason. The strongest motivation a person can have for laser removal of moles is an atypical mole that looks bad, their excision in this case having a preventive nature.
How to recognize a dangerous mole?
Malignant Moles - risk of melanoma is primarily at half asymmetrical ones which mean they do not overlap perfectly;
Irregular edges - edges are irregular or poorly defined belongs, most often a malignant moles;
Moles with more colors on the surface or irregularly divided Moles whose color changes over time shows the risk of malignant mole;
Moles with a large diameter have usually an increased risk of melanoma.
There are three ways a mole can be removed, which of them are at the discretion of the doctor who will perform the procedure and based on lesion appearance.
Surgical excision is performed under local anesthesia and requires the mole's removal with a scalpel. Flat Moles are the ideal candidates for this type of excision. If a melanoma is suspected, the size of the fragment that will be excised will exceed with about 1 cm margins of the mole to ensure removal of all potentially malignant cells.
Excision followed by suture of the wound and excised fragment will be examined histopathologically to determine its nature. The scar is linear and in different perpendicular places the sutures tracks will be visible. This kind of mole removal as opposed to the laser mole removal approach has the disadvantage that the scar is visible and unaesthetic. If you want the surgery for aesthetic reasons on visible places such as face, hands and legs the laser mole removal technique is the way to go.
Moles are being removed by protruding through electrocautery. After the skin is numbed with a local anesthetic, the mole from its surface is "shaved" with electrocautery. Suture is not used and little or no scar is visible, depending on size and location of the mole.
Laser mole removal
The laser mole removal is limited to the small and superficial ones. The laser mole removal is not one of the most common methods because the laser does not penetrate the skin deep enough to completely remove the deep lesions. The laser mole removal approach does not require sutures and the scar will look like a star.
Hairs growing from moles can be removed only by full excision of the mole.
We know surgery is a scary idea, but executed properly (with appropriate depth and safety margin), surgery does not present any risk.
There are a number of risk factors favoring skin cancer that is mole derived. They are:
Risks resection of moles are small and are represented by scars, infections, allergy to anesthetic used or nerve damage, in case of a particular lesion location. It is important to note that among the risks are not included the triggers of cancer misperception spread around by many people.
For avoiding laser mole removal, in the summer, when going to the beach, do not forget to also protect your moles: choose a cream with high protection, especially if you have a light skin (white or gray)!
