A review of cancer diagnoses from pathology tests at four hospitals found that up to 11.8% were in error, according to a study slated to appear in the Nov. 15 issue of the journal Cancer.

They recommended standardizing tests and error reports as initial steps toward improving safety. The Agency for Healthcare Research and Quality funded the study. Read the abstract.
