GBI Research, a leading business intelligence provider, has released its latest research report, "Melanoma Therapeutics Market to 2020 - Rising Prevalence and Evolving Treatment Algorithms to Drive Market Growth” Melanoma is a highly heterogeneous disease comprising Cutaneous Melanoma (CM), Ocular Melanoma (OM), Mucosal Melanoma (MM), melanoma of the internal organs, and, according to some classifications, melanoma of the soft parts (non-bony and non-cartilaginous tissues) of the body. CM is by far the most common form of melanoma, accounting for approximately 90–95% of all melanomas.
