Skin cancer is a disease that occurs by the development of cancerous cells in any of the layers of the skin.

Some symptoms

Referred to as the most serious type of skin cancer melanoma. Usually the first symptom of a melanoma is a change in the shape, color or texture of a mole. As in the majority of cases the melanomas are not painful, many people do not attend medical consultation, which means the progress of the disease. Melanoma can also appear as a new mole that can be black or abnormal. Melanoma diagnosed in time is treatable and curable. But if a melanoma is not excised in its initial stages, cancerous cells grow inward invading healthy tissues; which could lead to a metastasis. Some doctors use the ABCD rule so that their patients can differentiate a common mole from melanoma:

* Asymmetry: If half of a Mole is not equal to the other half
* Rims: the edges are irregular or uneven
* Color: many times the color is uneven and may vary between black tones, cinnamon and coffee
* Diameter: they tend to become larger

Usually in men, melanoma usually occurs on the trunk and the region of the head or neck; While in women it appears in arms and legs.
