New screening method uses a single drop of blood to test for 13 types of cancer

A novel new testing method uses a single drop of blood to test for 13 types of cancer. By testing for differences in the microRNA (miRNA) the test is able to accurately detect cancers of the breast, lung, stomach, colorectal tract, esophagus, liver, and pancreas, among others. “MicroRNAs constitute a recently discovered class of non-coding RNAs that play key roles in the regulation of gene expression. Acting at the post-transcriptional level, these fascinating molecules may fine-tune the expression of as much as 30% of all mammalian protein-encoding genes,” according to life sciences and diagnostics lab Exiqon. In lab tests using…
