Abstract: In recent years,the morbidity and mortality of colorectal cancer in China are increasing year by year. According to the studies,the increase in the incidence of colorectal cancer may be related to the growth of consumption of red meat and processed meat products. However,this correlation has been controversial. Therefore,the current research methods and their limitations of studying the correlation between red meat/processed meat products and colorectal cancer,as well as the potential risk factors of colorectal cancer relating to red meat/processed meat were reviewed in this paper. It provides a prospective to determine the relationship between cancers and red meat/processed meat products.
