"Sure," says the patient, rolling up a sleeve. She'd be one of the first to have "multi-cancer early detection" – MCED – blood tests that zero in on clues that cancer cells shed into the bloodstream. A treatment begun early is more likely to work. An MCED blood test could be a gamechanger for people who haven't had cancer.
