Diets and Risk of Cancer

Abstract

Robert Skopec

A new study is providing further evidence about the potentially life-threatening danger of drinking soda on a daily basis. Large, long-running epidemiological studies have also concluded that there is indeed a link between the foods a person eats and his risk of colon cancer. During this process, the bacteria produce compounds such as secondary bile acids that have been shown to cause inflammation and cancer in lab studies. A study by the University of Aberdeen has found first time that a higher concentration of the molecules that breakdown omega-3 fatty acids is associated with a higher chance of survival from bowel cancer. Results showed that a higher proportion of omega-3 metabolising enzyme to omega-6 metabolising enzyme is associated with less spread of the tumor and a greater chance of survival for an individual patient. Cancer stem cells can be put into hibernation by a little-known drug diphenyleneiodonium (DPI) according to researchers from the University of Salford, UK. DPI effectively switches off the stem cancer cells, preventing their proliferation. It was showed that as the number of mutant KRAS copies increases, the tumor’s aggressiveness and ability to metastasize also increases. Disruption of endogenous protective mechanisms determines the evolution of cancer.
