The common cancers in Western societies are being "fed" by arachidonic
acid metabolites, such as LTB4 and PGE2.  Go to www.pubmed.com and
search for cancer PGE2 and cancer LTB4, for example.

Just avoid highly unsaturated oils and the cancer might go away,
depending upon how damaged the body is.  Eating berries, dark
chocolate, and other rich sources of antioxidants (that are safe,
unlike something like massive amounts of rosemary) is a good idea too.

What you are reading are essays in failure.  I deal in the scientific
method and results.  I'm not interested in trying to make anyone feel
good, or "find a positive side to cancer."  Cancer results when cells
are so disrupted that they no longer have controls in place.  Too much
free radical damage and biochemical activity can do this, so if you
just pack your body with saturated fatty acid, and keep your
cholesterol levels "high" (200-220) while keeping it from getting
oxidized, you won't have to worry about all the garbage you hear about
eating "fiber" or taking "phytonutrient" supplements or any of the
other nonsense.
