 This research suggests that DNA methylation patterns can be used to detect early signs of cancer in patients' blood samples. The authors found that certain methylation patterns were present in patients' blood samples years before they were diagnosed with cancer. This could potentially be used to identify high-risk patients and allow for earlier intervention. This article was authored by Felicia Feilei-Chung, Sandra Gonzales Maldonado, Omelie Nemp, and others.
