The 1999 Cancer Prevention White Paper points out that, according to figures from 1991, 41 % of cancer sufferers were not undergoing orthodox treatment. This phenomenon was especially pronounced in victims of liver and lung cancer, two forms with a generally poor prognosis. The percentage of liver cancer victims not under orthodox treatment was 76 %, while the figure for lung cancer victims was 64 %.
「一九九九防癌白皮書」中，提出民國八十年的統計資料，有四成一的癌症病人未接受正規治療，尤其是預後不佳的肝癌與肺癌，肝癌患者未接受正規治療的高達百分之七十六，肺癌患者亦高達百分之六十四。
