Melanomas are divided into four major groups. Three start in situ and invasive later become the fourth form of melanoma is invasive from the start.

Superficial spreading melanoma is the most common type of melanoma. 70% of all reported cases are superficial spreading melanoma. Melanoma takes the top layer of the skin for aFor a long time before they invasive. Melanomas, the younger age group are usually the superficial Article

Lentigo maligna is similar in that it also affects the top layer of the skin for a long time before it deeper. The older age group is mostly affected by this type of melanoma. This condition can in the ears, arms and upper body to take, if they were constantly exposed to the sun. Lentigo maligna melanoma is to be an invasive form of the disease.

Acrallentiginous melanoma is the third form of melanoma, and like the first two, it spreads along the surface before invasive tuning. Acral lentiginous melanoma is sometimes darker on human skin. It is more common in Asians and African-Americans than Caucasians.

Nodular melanoma, the fourth type of melanoma is easily the most aggressive. It is the time of diagnosis of the disease. The most commonly affected areas are arms, legs, trunks (especially older people) and theScalp. Nodular melanoma accounts for 10% to 15% of all cases of melanoma.

Malignant melanomas are characterized by brown, black or bright spots, and large nodules with irregular contours. They sit on the skin surface and bleed. Usually they come in already existing moles. Melanoma in general objectives of the trunk in men. In affected women, arms and lower legs.
