Is there any evidence that omega-3, 6 or 9 or flax can be helpful in
thwarting cancer of the prostate? Is there any reason not to
supplement with these oils?

Thanks,
Fred

Hi Fred...I don't know about omega-9 fatty acids, but the general
consensus on the others is that omega-3's are helpful in the fight
against PCa, while omega-6's are not (due to the conversion of linoleic
acid to and arichidonic acid and prostaglandins, stimulators of the
inflammatory response and PCa cell growth).  As to flax, it contains
alpha-linolenic acid as the omega-3.  While not as bad as
alpha-linoleic acid (omega-6), at least one study has shown that it too
stimulates PCa cell growth.  Still, with flaxseeds, their is enough
good "stuff" in them that ground seeds are considered to be acceptable
by some, while all agree that the oil is to be avoided.

Here is a  link that may prove helpful.  The first link

http://cancer.ucsf.edu/crc/nutrition.php

takes you to a UCSF website.  Once there, click on "Nutrition and
Prostate Cancer" to download a PDF file on nutrition and PCa.  It
covers omega-3, 6 and flax, as well as diet, supplements, herbs, etc.
It even provides some recipes!

Here is a copy of the article on flaxseed...Best wishes and good
health, 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.

Long, excruciatingly detailed, well-documented debates among experts
over at sci.med.diseases.cancer disagreed on the impact of walnuts on
PC, but agreed strongly that flaxseed will promote PC growth. I gave my
flaxseed oil capsules to my wife and reduced my walnut consumption.
Google that forum for discussions of omegas, flax, etc. and key in to
discussions involving Matti Narkia.

Theralogix makes a fish-oil supplement called TherOmega, which I would
look into.  I highly recommend Theralogix products because I have been
reviewing this company pretty extensively in recent days.  (See my
comments on "Health Food Trauma, thread.)  This co. focuses exclusively
on urology-related products (also, bladder, UTI supps.).  Theralogix
has a panel of very distinguished and highly qualified doctors who
consult about what goes into their products, and the company also seems
to have very high quality standards.  Here's a sample from the
Theralogix website:  (Theralogix.com)

TherOmegaTM is a natural source of omega-3 fatty acids derived from
pharmaceutical-grade fish oil. This supplement has been independently
tested and certified for content accuracy and purity (by NSF?
International) and for freedom from contaminants such as mercury, lead,
and PCBs (by the International Fish Oil Standards Program). TherOmegaTM
is the only fish oil supplement that has been tested and certified by
both of these organizations. TherOmegaTM contains the following
ingredients:

Omega-3 Fish Oil    550 mg
EPA    350 mg
DHA    200 mg

60 day supply: $25.

Also, if you go to their site and click on "medical journal articles"
you will be linked to the latest research pertaining to the subject
you're interested in.  So have a look.  Anyway, this is from their site
(abridged).

1: Cancer Causes Control. 2006 Mar;17(2):199-208.

Diet after diagnosis and the risk of prostate cancer progression,
recurrence, and death (United States).

Chan JM, Holick CN, Leitzmann MF, Rimm EB, Willett WC, Stampfer MJ,
Giovannucci EL.
Department of Epidemiology, University of California, Room A622, San
Francisco, CA, 94143-1695, USA. june@uorg.ucsf.edu

OBJECTIVES: We examined post-diagnostic diet and risk of cancer
progression in a cohort of men with prostate cancer from the Health
Professionals Follow-up Study.
CONCLUSIONS: These data suggest that diet after diagnosis may influence
the clinical course of prostate cancer, and fish and tomato sauce may
offer some protection against disease progression.

Also:  Someone from this group had referred me to another company that
I was impressed with, so I want to pass it on. Brownwood Acres, a
family-run business which primarily sells fruit from local orchards,
seems to offer a very high-quality fish oil supp. as well.  (Look under
"supplements.")   This is from BA website:

Wild Alaskan Sockeye Salmon Oil Capsules

These pharmaceutical grade fish oil capsules contain ONLY pure Wild
Alaskan Sockeye Salmon Oil. Each 1000 mg softgel provides approximately
260 mg of total omega-3 fatty acids, including 150 mg of EPA and DHA.
In addition, laboratory analysis reveals an amazing 32 distinct
additional fatty acid molecules you're unlikely to find in highly
processed "purified" alternatives. Truly a unique health-promoting
product. Purity and potency guaranteed.

Price is $35 for three mos.  That sounds reasonable.

I don't know which of the above products is better, but maybe someone
else does.

BTW, Brownwood Acres also sells locally grown pom products, such as pom
concertrate capsules and even fruit bars.

My only suspicion of Theralogix is that they have a nice little
kick-back incentive with Doctors. Doesn't make them right or wrong,
just makes me wonder. They also claim to be conducting a clinical trial
on their "Prostate 2.2" supplement (which used to cost $60/2 mo.
supply, now $70/2 mo. supply). I could not find the trial using my own
research. I'm now buying the equivalent of Prostate 2.2 at half the
cost by combining 2 other supplement packages. Just raising questions
... , if their product is really better, I'd switch back.

I don't work for Theralogix, but I can tell you this:  According to
their website, "financial info" section, they do not pay *any*
commissions to doctors.  That doesn't mean they can't compensate the
docs in some other way, but that's something else.  I feel comfortable
with their supplements precisely because they were not recommended by
any MD.

I haven't seen anything on the Theralogix website about a research
study, but if you want info about that you can just email them.

If you are comfortable with your current regimen there's no reason to
change.  In my case, if I bought the 5 components of the supp,
separately (in a local store), it would cost me more than $35/month.

Leah, thanks. My uro told me about Theralogix and gave me a code to
type in when ordering. It seemed obvious to me, but maybe it's all OK.
I took their product for over 2 years and then started pinching pennys.

The clinical trial information was in a flyer from Therlogix with one
of their shipments. I was trying to verify from an independent source.
I'll look up the info. if you're interested (on the trial).

Fred--

Just came across this on acor ml.  Dr. Myers has a lot of followers.

Ralph,

For fish oil, Dr Myers recommends Nordic Naturals.

Yes, I'm the one you spoke to.  I will respond on the "stress
incontinence" thread.

I tried to find a website that would permit you to track the amount of
Omega-3 you are eating.  I found www.calorie-count.com and that does
not include the oils.  I tried www.nutritiondata.com and that database
is incomplete.  For instance, I could not find the Back-to-nature
breakfast cereal that I eat every morning.  Prior to making
significant changes to my diet, I want to assess where I am starting.
Has anyone been able to find a site that will give you the information
that may be valuable to people with PCa and store it in a database
without inputting the data by hand?

Thanks,
Fred
