Abstract
Truth telling of cancer as informed consent is one of the medical techniques. Truth telling has three factors. The first is the selection of cases with indication, the second is technique of conversation of truth telling and the third is support system as management after truth telling.
To select the cases with indication of truth telling, the most important factor is the purpose of truth telling. The evaluation of safety and/or risk is also important.
Through the acceptance of death we can evaluate the success of truth telling.
The acceptance of death is thought as good result. The author observed 62% acceptance of death in cancer patients who were told truth.
We can find the good conditions for truth telling by analysing the relations between acceptance of death and the conditions of the cancer patients before truth telling.
