However, a study done in the United States showed that about a third of patients wished that they did not know the truth. Thus in deciding whether or not to tell the patient, the individual's own character and ability to deal with the news must be evaluated in order to avoid impairing the effectiveness of the treatment.
但是根據美國一份研究報告顯示，大約有三成的病人不希望知道真相，因此在決定是否告知時，也必須要考量個別病人的個性是否能承擔，以免影響治療效果。
