Can cancer blood tests live up to promise of saving lives?
Associated PressJoyce Ares had just turned 74 and was feeling fine when she agreed to give a blood sample for research. It’s an open question whether such cancer blood tests — if added to routine care — could improve Americans’ health or help meet the White House’s goal of cutting the cancer death rate in half over the next 25 years. That’s not the case for devices like blood tests,” said Dr. Barry Kramer of the Lisa Schwartz Foundation for Truth in Medicine. For some, blood tests led to scans that never located a cancer, which could mean the result was a false positive, or it could mean there’s a mystery cancer that will show up later. Although Ares feels lucky, it’s impossible to know whether her test added healthy years to her life or made no real difference, said Kramer, former director of the National Cancer Institute’s Division of Cancer Prevention.
