The scientists with the Johns Hopkins Sidney Kimmel Comprehensive Cancer Center say they have used the test to detect early stages of colorectal, breast, lung and ovarian cancer in dozens of patients.
The blood test is one of many in early development being tried to diagnose and treat cancer earlier. The Hopkins researchers say their test is different because it detects the DNA directly from the blood.
