Melanoma is a particular type of skin cancer. It happens when the melanocytes (the pigment cells) become cancerous. Most pigment cells are found in the skin, although melanoma can also occur in the eyes (ocular melanoma) and other parts of the body. There are many types of skin cancer but, of all skin cancers melanoma is one of the common types, though it is much less common than basal cell and squamous cell skin cancers. Melanoma is a rarer but more dangerous type of skin cancer than other types due to its faster spreading nature. It is very rare in people with dark skin. Melanoma is the best known and most important skin cancer to prevent. The treatment of skin cancer is much similar to that of other cancers, except that the aim of skin cancer therapy is invariably to completely remove it, which is possible because of its location. The other less common treatments for skin cancer include chemotherapy, photodynamic therapy (light and drug therapy, but not against melanoma), biological therapy and, although not usually, rarely radiation therapy
Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
