We have not summed up these studies in words yet. The most important papers are listed under Sources.
Verdict
Fenbendazole has been studied for lung cancer in animals, not yet in people.
Unproven means: it was only tested in animals or cells, or there is too little or mixed data from people. How we rate claims
What this means for you: Results in animals or in cells often do not hold in people. Do not stop or change your medicines because of it. Ask your doctor before you start taking it.
