The mole size and number demonstrates the patient’s risk of developing melanoma (skin cancer).

The mole site is usually on the trunk in men and within the calves in women, all though it may develop in any other region of the skin. A dysplastic nevus is the most harmful form of moles because it easily develops into skin cancer (melanoma). Genetic disorders have been recognized as the main cause for the formation of the mole. However, environmental conditions related to skin exposure to sun and tanning are acknowledged as more contributing factors. Preventions of dysplastic nevus include the use of sunscreen although the year, avoidance of tanning and regularly covering up the body.

Blue nevus

This mole is one of the harmless skin pigments. It’s usually very deep into the skin and appears as a gray-blue patch or blue-black nodule. Blue nevus is classified as patch blue nevus, malignant blue nevus, nevus ceruleous, deep penetrating nevus, epithelioid blue nevus, cellular blue nevus and amelanotic blue nevus. Causes of this mole are closely related to dysplastic nevus; this makes the two types to mimic each other sometimes. Blue nevus prevention is similar to dysplastic nevus.

Spitz nevus is another lethal form of moles also referred to as benign juvenile melanoma, though the juvenile has been dropped recently to stop confusion.

The mole’s origin is yet to be discovered, but many research ties the cause with sunburn. Prevention is to avoid skin exposure to UV light and to avoid tanning.

Treatment of Moles

Skin biopsy is the most prominent treatment used by pathologists. And proper care is required for removing moles from the beginning to avoid its regeneration. Most importantly, the original mole’s location and size contribute to the most suitable method to be used. Recently, Laser, surgery or electrocautery has been very effective in the removal of moles.
