Core tip: Colorectal cancer (CRC) is one the major worldwide health problems owing to its high prevalence and mortality rates. It is reported that over 40000 of the adult United Kingdom population are diagnosed with CRC each year. In case of early diagnosis CRC is also one of the most curable types of cancer (cure rates > 90%). This article gives an overview study of causes and etiology of colon cancer, distinct stages from stage from 0 to IV, some novel therapies are also briefly discussed in article such as receptor (epidermal growth factor receptor, folate receptor, wheat germ agglutinin, VEGF receptor, hyaluronic acid receptor) based targeting therapy; colon targeted proapoptotic anticancer drug delivery system, gene therapy. Recent developments in screening, prevention, biomarker and genomic analysis, nutritional supplement therapy, vaccination, and chemotherapy have improved detection and significant reduction in mortality statistics.
