Go to http://www.google.com and enter "flaxseed oil and prostate cancer"
(without the quotes).  The general opinion is that ground flaxseed (NOT
THE OIL) will help slow or even prevent the spread of prostate cancer.
Get the whole seeds, grind a weeks supply (a coffee grinder will do) and
keep the ground seeds in the refrigerator.  I put two rounded
tablespoons on my cereal.  If you buy the oil, it is of questionable
quality and doesn't keep very well.  The preground flaxseed doesn't keep
as well as the whole seeds.

Dr. Budwig's cottage cheese plus flaxseed protocol has purportedly
cured thousands of cancer.  However, like so many other aspects of
PCa, there are differing opinions on the benefit of flaxseeds, or
their oil, in the battle against PCa.  Here is an opinion from the
"other" camp which includes comments / studies by Dean Ornish and
"Snuffy" Myers...Ron

Flaxseed oil supplement may be harmful to men
By WILLIAM P. MARLEY - guest column
Flaxseed nutritional supplements have some positive health benefits.
Recent research has shown, for example, that they may help prevent
heart disease and breast cancer. We no longer recommend flaxseed oil
to our male patients in the Diabetes Exercise Center and Cardiac
Rehabilitation Program, however, because current medical opinion has
related these supplements to prostate cancer.
Dr. Dean Ornish's research first demonstrated that heart disease can
be reversed with therapeutic lifestyle changes such as exercise,
sensible nutrition, smoke cessation and meditation.
I asked him about evidence that indicates flaxseed oil may promote the
growth of prostate tumors. Does flaxseed oil cause prostate cancer, or
does it stimulate the growth of existing prostate cancer cells? Also,
does this warning apply to ground flaxseed meal?
"The omega-3 fatty acids can be highly protective against heart
disease," Ornish responded. "Flaxseed oil and fish oil are two
concentrated sources of omega-3 fatty acids. However, some scientific
evidence has caused me concern about recommending flaxseed oil because
it may accelerate the progression of prostate cancer. Fish oil, in
contrast, does not seem to have this harmful effect on prostate
cancer."
Flaxseed oil is a rich source of alpha-linolenic acid, which has been
shown to be beneficial in both heart disease and breast cancer.
According to Dr. Charles E. Myers Jr., however, a scientist at the
University of Virginia Medical School in Charlottesville, available
research suggests that alpha-linolenic acid may be dangerous for
prostate cancer patients.
"Five out of six studies found an increase in the risk of prostate
cancer associated with alpha-linolenic acid," Myers said. "Our
laboratory, as well as others, found that alpha-linolenic acid is one
of the most powerful growth stimuli for human prostate cancer cells."
After reviewing Myers' findings, Ornish commented further.
"Thus, I now recommend fish oil, rather than flaxseed oil, for men and
either for women. The same applies to flaxseed meal as well as the
oil, although flaxseed contains a number of phytochemicals, such as
lignans, that are of potential value. One of the major lignans in
flaxseed is secoisolariciresinol, a phytoestrogen and antioxidant.
"However, you can get these phytoestrogens in other foods, such as
soy, without the potential problems of flaxseed and flaxseed oil."
Always consider food and vitamin supplementation carefully. Before
beginning any new nutritional regimen, discuss it with your physician
to be informed of any potentially harmful side effects.
