I think this claim is disputed. See for example
http://www.hhdev.psu.edu/research/Stearic.htm From what I have
read recently, stearic acid appears to be neutral in its effect
on cholesterol.

Stearic acid in membranes would tend to *decrease* fluidity.

Yes, but they don't say (here) which way the ratio works. The
above quotation suggests that a *lower* ratio of stearic to oleic
acid in membranes is indicative of malignancy. In neither case
is their any indication of a causal role, incidentally.
