Melanoma
Melanoma (pronounced /ˌmɛləˈnoʊmə/ ( listen)) is a malignant tumor of melanocytes which are found predominantly in skin but also in the bowel and the eye (see uveal melanoma). It is one of the less common types of skin cancer but causes the majority of skin cancer related deaths. Malignant melanoma is a serious type of skin cancer. It is due to uncontrolled growth of pigment cells, called melanocytes. Despite many years of intensive laboratory and clinical research, the sole effective cure is surgical resection of the primary tumor before it achieves a Breslow thickness greater than 1 mm.
Around 160,000 new cases of melanoma are diagnosed nationally each year, and it is more frequent in males and Caucasians. It is more common in Caucasian populations living in sunny climates than in other groups. According to a WHO report about 48,000 melanoma related deaths occur worldwide per year.
Malignant melanoma accounts for 75 percent of all deaths associated with skin cancer.
The treatment includes surgical removal of the tumor, adjuvant treatment, chemo- and immunotherapy, or radiation therapy.
