Genetic methylation is a process where small chemical tags are added to DNA, affecting how genes are turned on or off without changing the actual DNA code. This can impact cancer risk because it can sometimes lead to harmful genes being turned on or protective genes being turned off. By studying these changes, we can identify people who might be at a higher risk of developing cancer, allowing for earlier detection and possibly preventing the disease from progressing.

Diet plays a crucial role in preventing colorectal cancer. Eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins can help lower the risk. These foods are high in fiber, which aids digestion and may help protect against cancer. Limiting the intake of red and processed meats, as well as avoiding excessive alcohol consumption, can also reduce risk. Healthy dietary choices can help maintain a healthy weight and improve overall gut health, both of which are important factors in reducing the likelihood of developing colorectal cancer.

Exercise can have a significant impact on DNA methylation, a process that affects how genes are expressed in our bodies. Regular physical activity has been shown to influence the methylation patterns in DNA, which can play a role in turning certain genes on or off. These changes can potentially reduce the risk of various diseases, including cancer, by promoting the activation of protective genes and inhibiting harmful ones. By engaging in regular exercise, individuals may positively influence their genetic expression, contributing to better overall health and potentially reducing disease risk.
