How do moles appear?
Most people are born with a number of moles. The other ones appear most frequently until around the age of 40 years. Prolonged exposure to the sunlight appears to play an important role in the development of skin moles, especially those atypical or dysplastic, with a potential to be cancerous.
The role of heredity in the occurrence and development of moles is recognized of being one of the major roles. In some families there are more people with a special type known as dysplastic moles, which is associated with a higher frequency of skin cancer.
Depending on the position on the body where they are found, moles may go unnoticed or may cause constant discomfort by rubbing with clothing or other body parts, or because their presence in areas where they can be easily damaged, such as shaving, trimmed and so on.
Many moles are considered to be unaesthetic, by being located in the exposed areas of the body (face, hands, feet etc.) and by size, shape or color. Others may degenerate as a result of trauma or excessive exposure to sun in atypical moles with the risk of turning into melanoma.
Atypical moles are usually large, with irregular toothy edges, irregular in shape, are asymmetric, have an uneven color and sometimes bleeding. They must be examined by a specialist to detect if they are carcinogenic or not. Atypical moles do not always prove to be carcinogenic, but the risk of developing skin cancer from them is higher than in normal moles.
These are the main reasons for which a person would want a mole removal, whether atypical or not. The strongest motivation a person can have to perform a mole removal is an atypical mole or an unaesthetic one. But a person may require a mole removal for the ones that produce constant physical discomfort which may lead to the mole's bleeding, or those that are considered to be an unaesthetic mole resulting in an improvement the person's image.
There are two surgical methods with which you can get a mole removal:
The mole's type of removal is determined by the surgeon and depends on how it looks. The shave excision is used to treat prominent moles, after the skin is numbed with a local anesthetic, the mole is removed from its surface. If the mole is flat or melanoma is suspected, a biopsy is necessary. By this method, the doctor removed the mole and its depths until the skin is then sutured.
Although laser therapy has been tried in order to eliminate moles, it is not currently used in most cases, because most moles are pretty well anchored in the skin and the laser beam does not penetrate deeply enough. For small moles, superficial laser can vaporize the tissue that must be removed and cuts and sutures are no longer necessary . Hairs growing from moles can be removed only with the full mole's removal.
The surgery for moles removal is done surgically under local anesthesia. If you have several moles removed while the operator may be general anesthesia or intravenous sedation.
Moles removal risks - Risks of surgery for resection of moles are small and range from infection to allergy to the anesthesia or nerve damage. Often, surgical removal of moles result is a scar on site which should be considered if resection is performed for aesthetic reasons.
