Blood Test Gives Early Warning of Melanoma Relapse

“A blood test can detect changes in tumor DNA, potentially helping doctors detect melanoma relapse far earlier, according to a study in England.

“Scientists at Cancer Research UK found the blood test detects mutations in circulating tumor DNA indicating potential drug resistance or relapse, which would allow treatment to start earlier and increase the chance for a patient’s survival.

“Although the study was small, and scientists say the test’s accuracy needs to be tested in a much larger trial before it is used in clinics, any possibility of improving how cancer is tracked will improve treatment.”
