Previous studies have reported rapid increases in colorectal cancer incidence rates in economically transitioning countries in many parts of the world, likely reflecting changing dietary and physical activity patterns.
The rising trend in incidence and mortality from colorectal cancer is more striking in affluent than in poorer societies and differs substantially among ethnic groups. Although changes in dietary habits and lifestyle are believed to be the reasons underlying the increase, the interaction between these factors and genetic characteristics of the Asian populations might also have a pivotal role.
The average population risk for developing colorectal cancer in
Environmental factors and genetics play varying roles in the aetiology of colorectal cancer. About 80% of colorectal cancers arise sporadically with no evidence of genetic susceptibility. In the remaining cases, genetic factors play a significant role. Hereditary forms of colorectal cancer are distinguished by the presence or absence of polyposis5.
