Cancer
According to the Journal of Clinical Oncology, cancer misdiagnoses occur as much as 28 percent of the time, and up to 44 percent for some types of cancer. A nationwide survey of 400 cancer specialists found that leading the list of most misdiagnosed cancer conditions are lymphoma, breast cancer, sarcomas and melanoma. The reasons for misdiagnosis include fragmented or missing information, inadequate time for patient evaluation, and incomplete medical history.
