DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Fecal immunochemical test and mt-sDNA test are equally effective for colorectal cancer screening

Commercially available noninvasive screening tests for colorectal cancer-;a fecal immunochemical test (FIT) and the multi-target stool DNAtest (mt-sDNA; or Cologuard®)-;are equally effective for screening patients with early-stage colorectal cancer.
