BACKGROUND BACKGROUND

MELANOMA - short for “MELANOCYTOBLASTOMA” – is a malignant tumor originating from MELANOCYTES - cells that constitute the human body’s MELANOCYTIC SYSTEM. Widely recognized as a type of skin cancer, melanoma, in fact, is not derived from skin cells, and instead truly represents a neuroectodermal neoplasm (a tumor from embryonic tissues that form the brain, the spinal chord, and nerves). Melanoma may affect MELANOCYTES throughout the body, wherever they are located (e.g. skin, brain, mucous membranes, etc.). Melanomas most frequently – but not exclusively - arise in the skin, simply because at this site the total amount of MELANOCYTES is the highest in number.

Accounting for about 40,000 - 50,000 new cases in the U.S. per year, and killing about 10,000 patients out of them, malignant melanoma is one of the most dangerous cancer challenges of nowaday's time. Similarly alarming incidence figures have been reported in many other countries, especially in Northern Europe and Australia/New Zealand. With a three-decades incidence increase of more than 100%, and an increase in mortality by more than 30%, melanoma is one of the most lethal cancers in mankind. Currently, one out of 70 U.S. citizens will be afflicted by melanoma sooner or later.

Despite the fact that melanoma has the fastest incidence increase among all cancers over recent years, it is yet highly preventable and can be diagnosed early enough to prevent its fatal course. Possible causes for melanoma - as is known to date - are pre-formed and/or acquired GENETIC ALTERATIONS within the MELANOCYTIC SYSTEM, with inadequate UV RADIATION EXPOSURE (intermittent high-dose exposure, repeated sunburns) adversely impacting on the regulatory control mechanisms of MELANOCYTE DIFFERENTIATION.
