It was discovered that four years ago, Chiba University Hospital had an operation on a woman in her 50s who had cancer in her left breast and accidentally removed her right breast.
This was revealed at a press conference by Chiba University Hospital on the 29th.
According to this, a doctor at Chiba University Hospital mistakenly worked for a female patient in her 50s who had cancer in her left breast at another hospital in the prefecture where she worked once a week four years ago. He also made a diagnosis that cancer was found.
The doctor then performed an operation to remove both breasts of the woman at Chiba University Hospital, but a pathological examination of the removed specimen revealed that the right breast did not need to be removed. It means that.
Chiba University Hospital said that the doctor's failure to check the pathology report was the biggest cause of the mistake, and when the doctor explained the test results to the patient, he always checked with the patient and the patient. If the medical treatment spans two facilities, another doctor will be in charge of the first visit or read the referral letter to prevent recurrence.
At the meeting, the doctor in charge said that he had already retired from the university hospital, and at the meeting, Deputy Director Masayuki Otsuka of Chiba University Hospital said, I apologize.
