As Chao Ko-shih says of 200-300 advanced cancer patients she has cared for over the last three years: "When they were in pain, 100 % of them wanted to die, but when they got relief from pain and control over their illness, not one wanted to die."
台大腦神經外科主任趙可式指出，近三年來，她從事癌症末期安寧照顧的二、三百個癌症末期病人，「他們在痛的時候，百分之百都想死，經過疼痛緩解、症狀控制後，沒有一個人再想死。」
