Melanoma is the most dangerous type of skin cancer, which develops from the pigment-containing cells (melanocytes) in the skin.  It is often curable if you find it early.  Melanomas typically occur in the skin, but may rarely occur in the mouth, intestine, or eye. In skin cancer the melanocytes become malignant and multiply excessively. One of the most important causes of melanoma is exposure to too much ultraviolet light in sunlight. The use of artificial sources of UV light, such as sunbeds, also increases the risk of getting melanoma.  

The most common sign of melanoma is a new mole or a change in an existing mole.  This can occur anywhere on the body, but the most commonly affected areas are the back in men and the legs in women.  Melanomas are uncommon in areas that are protected from sun exposure, such as the buttocks and the scalp. 

In most cases, melanomas have an irregular shape and more than one colour. The mole may also be larger than normal and can sometimes itch or bleed.  If you have a mole that is changing progressively in size, shape or colour make sure to have to checked by a Dermatologist without delay.
