This case involves a female patient who had been under the care of the same dentist for several years, with whom she consistently kept twice-yearly appointments. The woman had suffered from oral cancer which had been successfully treated one year prior to the events of the incident in question. The patient had been under the care of another physician who had been monitoring her for recurrence of cancer, and had taken a biopsy of the previously affected area that did not reveal the presence of cancer. However, the woman’s cancer had reoccurred, and the negative biopsy result was evidently obtained in error. It was claimed that the cancer may have been visible in dental x-rays taken around the time of the biopsy.
