Recently, genes have been found that increase the chance of getting colorectal cancer in people that eat red or processed meat. There is also another gene that US researchers found that decreases this risk when eating fruit, vegetables, and fiber. A study was done to prove this finding in which people with this cancer were compared with healthy individuals. Subject's genes were sequenced to determine if there was a correlation. They found that gene rs4143094 affects 33% of the population and was found in the majority of the cancer positive subjects. This gene was also in the same area of other known genes, such as GATA3, that have been linked to cancer. These findings could help prevent future outbreaks of these types of triggered cancers. This is one example of how genetic sequencing can be used to understand the patients susceptibility to colorectal cancer. Changing their diets according identification of these genes could help prevent future health problems, including other cancers or genetic flaws that could be prevented through a better diet.
