You seem to have very low reading comprehension, nowhere did I say low-dose naltrexone cures cancer. There is a youtube video about someone whose cancer was cured using low-dose naltrexone.
Dismissing an unseen Youtube video given no other evidence than that it is sourced from YT seems reasonable, rational even. The prior probability of a randomly selected YT video being trustworthy is probably a lot closer to 0 than 1.
