Due to concerns about harmful side effects, even products which can be used to treat cancer are not being tested, since the agents used to control the growth of cancerous cells typically harm normal, healthy cells. This being the case, how can such products be rashly approved when it's not possible to carry out more thorough testing on animals and humans?
至於癌細胞抑制功效未開放，則是考慮「有一好就沒二好」，抑制癌細胞的成分往往也會傷害正常細胞，在沒辦法進行更深入的動物及人體測試的情況下，如何能輕率認證？
