At the Clinic Hospital in Barcelona, Spain, 167 cancer patients and 380 hospital health care workers were interviewed about cancer diagnosis disclosure. Only 25 patients (15%) were correctly informed of their diagnoses. Breast cancer patients were significantly more often informed than patients with other malignancies (p less than 0.05). Two hundred seventy-two of 380 hospital health workers interviewed (71%, p = 0.00) would want to know their own diagnoses should they suffer from cancer in the future, but only 19% (p = 0.00) would want such a diagnosis revealed to their similarly afflicted relatives. This information model, based on cancer taboo, is largely preferred by these healthy people and is followed by doctors, patients and family members. To inform our patients better, the mandatory uniform disclosure of the true diagnosis is not likely to be constructive at present. In our opinion a pragmatic approach is more realistic and humane. Nevertheless, we must hope that more modern cancer education will lead to the gradual elimination of this taboo in our society.
