DNA methylation—a better tumor early screening marker

Cancer is one of the leading causes of morbidity and death in the world, and about 1 out of every 6 deaths worldwide is due to cancer. According to the "2022 National Cancer Data Report", there are 4.064 million new cases of cancer in the country, and almost 8 people suffer from cancer every minute. Combined with the latest 2020 global cancer burden data previously released by the WHO.

The development of cancer is a multi-stage slow process, which generally takes 10 to 15 years from normal to precancerous lesions. Early detection, early intervention, and early treatment are currently the best means of cancer prevention and treatment. At the same time, early detection, early intervention, and early treatment can also greatly improve the effective treatment and survival of patients.

Studies have found that the occurrence of cancer is accompanied by changes in DNA methylation patterns, including retroelements, centromeres, and hypomethylation of proto-oncogenes. Changes in methylation patterns play a key role in the occurrence and development of tumors, and exist almost throughout the development of tumors including precancerous lesions. Therefore, more and more studies will use DNA methylation detection as a marker for early screening of cancer .
