Q: How Common Is Cancer Misdiagnosis?
Various forms of cancer (breast, colon, and lung) make up three of the top five most commonly misdiagnosed medical conditions. In one study, Johns Hopkins found a 1.4% error rate in pathology tests in patients referred for cancer treatment. Another study found that common procedures misdiagnosed prostate cancer in 6 out of 535 samples. Needless to say, the occurrences are not uncommon and the risks are always considerable.
