As of today there is no reliable diagnostic biomarker to distinguish benign tumors from malignant tumors. Global changes in DNA methylation and DNA promoter hypermethylation are important events in tumorigenesis. Promoter hypermethylation can cause silencing of tumour suppressor genes or lead to abnormal...
