A genetic test of breast cancer tumors helped identify women whose survival odds would not be greatly improved by chemotherapy. But that test isn't as precise as women and doctors might like.

Some genetic tests for a common cause of sudden heart failure can be wrong, researchers say, because the underlying science didn't take into account racial diversity.
