This is false correct?

Question

In one of Kalos's many posts, at http://answers.yahoo.com/question/index;_ylt=Aoz6xe.mKvR0b24fgcMipe7sy6IX;_ylv=3?qid=20071204092537AAM2FTx&show=7#profile-info-7M8Z3dELaa

He said the following
"Gerson was an mid-century crackpot whose diet ideas have been repeated and modified in modern Altmed diets. Essentially, he believed diseases — especially cancer — were caused by stagnant toxins and inadequate oxygen"
(along with the standard diabtribe about how this is all wrong).

I gave a good reply to it (link to youtube video is at the question), but when I read that specific part over again, I believe that I found a false hood. Tell me if I'm correct.
Cancer occurs when a cell switches from using oxygen to fermentation (and many chemicals have been shown to help cause this aka carcinogens). Given that fact, does that mean his assertion is completely innacurate? (or am I not connecting the two ideas properly).
This isn't meant to be an anti Kalos post, I just want to know if I'm correct.

Answer 1

A guy named dr otto warburg discovered that when a cell turns cancerous it switches from being aeorbic and using oxygen for respiration to becoming aneorobic and utilizing fermentation for energy instead.
I also think that if toxins don't leave your body, then they cause problems.
However, why are you even trying to prove this point? You might as well yell at a brick wall, he won't listen. Everytime you've actually called him on something that cannot be debated he either doesn't respond or deletes what he said. In this case it will just get a flame and be ignored. Have fun trying to reason with him. I'd rather just laugh at the whole thing personally!

Answer 2

"Cancer occurs when a cell switches from using oxygen to fermentation"

False. Don't know where you got this idea from, but cancer cells are metabolically similar to healthy cells.
