For instance, if we could find a marker for malignancy in endometriosis then it would be possible to develop a blood test that would tell us if a patient had a risk of developing cancer later in life."...... single-stranded viral DNA containing a mutational marker gene, the researchers (using specialized laboratory techniques) were able to identify which DNAs contained mutations and which did not.
