Few comments:
1) For those of you complaining about big pharma, note that Panacur C, the formulation of Fenbendazole that was used by the guy in the original article, is made by Merck, which is a huge pharma company.
2) Most of the studies showing anti cancer effects of Fenbendazole are in vitro studies (i.e., it can kill cancer cells growing in a dish). There are many, many compounds that show in vitro anti-cancer activity but are not successful in humans.
3) There are some in vivo studies in mice that do show that Fenbendazole slows the growth of tumors, but there are others that show that it has no effect.
4) There are many anecdotes of unorthodox treatments mysteriously curing patients supposedly deemed incurable. I am very happy for those lucky patients, but the only way to determine if the treatments actually work is through controlled clinical trials. Sadly, in the majority of cases those initial anecdotes don’t end up being reproduced in the controlled trials. It looks like there is currently 1 trial underway investigating Mebendazole, but none currently registered using Fenbendazole.
5) There are almost no experts in the field who still think that chemo is the best or most effective way to treat cancer. There are many alternatives under investigation, but treating cancer is extremely complicated.
6) In case anyone feels the need to ask, no I don’t work for a big pharma company, but I am a scientist at a major medical center and do spend a lot of my time studying cancer therapies.
