|Skin cancer is malignant in nature. There are many in nature but mostly 70% people suffer with basal cell carcinoma (Bcc) and remaining 20% with squamous cell carcinoma (Scc). Rest of them suffers with melanoma. The basic reasons causing cancer are exposure to radiation, heavy metals etc. Head cancer and neck: mostly bcc cancer is observed in head and neck. Radiotherapy and chemotherapy play an important role in controlling cancer. 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.
