Abstract

Case-control studies, and several prospective cohort studies, indicate that the risk of developing colorectal cancer is decreased in individuals who consume high levels of vegetables and fruits, and is possibly increased at high intake levels of meat and (saturated) fat. A new generation of prospective studies, following a multi-cohort design, is currently being set up in populations with diverse dietary intake patterns, and these may provide more detailed and more conclusive evidence on relations between nutritional factors and cancer risk. By including measurements of biomarkers in blood or tissue specimens, prospective epidemiological studies may also increase understanding of etiological pathways relating lifestyle factors to cancer development, and may thus help to identify nutritional factors that would need to be modified to prevent the disease.

Cancer Incidence & Mortality

Cancer has emerged as a global concern due to its increase in incidence and mortality. Efforts are underway to evaluate and develop action plans to reduce the global burden of cancer. Currently, lung cancer, breast cancer and prostate cancer are the leading causes of cancer mortality. Here is the latest research on cancer incidence and mortality.
