Welcome to the group, Fred.

Sorry about the cancer.  You've come to the right place.  We've all been
through it.

Interesting question.  Wish I knew the answer.  I think the latest we heard
was it's probably good for the heart and joints but neither hurts nor helps
those with prostate cancer.  I'm sure you will hear a better response
shortly.

Here is one supplier's claim:

Fish and Omega-3 Fatty Acids

Recent research has shown that eating fish more than three times per
week decreases the risk of prostate cancer, especially advanced
prostate cancer. The Health Professionals Follow-up Study, which
followed 51,529 men for 10 years, showed that men who ate more fish
after being diagnosed with prostate cancer had a reduced risk of
prostate cancer recurrence. This study also showed a reduced risk of
prostate cancer, as well as death from prostate cancer, in men who ate
moderate to high amounts of fish. The benefit was greatest for
aggressive prostate cancer, which occurred 44% less often in the men
who ate large amounts of fish compared to those who ate little fish.

It is thought that these benefits can be attributed partly to the
unique omega-3 fatty acids found in fish. These fats, eicosapentaenoic
acid (EPA) and docosahexaenoic acid (DHA), are found in fatty fish and
seafood such as salmon, mackerel, sardines, herring, trout, and tuna.
All fish contain some EPA and DHA, but in smaller amounts. Laboratory
experiments suggest that these two fats slow the growth and spread of
prostate cancer.

In addition to the benefits for your prostate, DHA and EPA may decrease
the risk of coronary heart disease and ischemic stroke, decrease the
risk of sudden death from heart disease, decrease serum triglyceride
levels, decrease the risk of blood clots, slightly lower blood
pressure, and decrease inflammation. These fats also appear to enhance
the effectiveness of cholesterol-lowering medications. Because of this
convincing evidence, the AHA (American Heart Association) now
recommends that all adults eat a variety of fish, particularly fatty
fish, at least twice weekly. The AHA recommends that adults with heart
disease consume a total of approximately 1 gram per day of DHA and EPA
from fish or fish oil supplements.

Consuming a diet rich in fish, along with whole grains, soy,
vegetables, fruits, nuts and seeds, should help reduce your risk of
prostate cancer, as well as your risk of heart disease and sudden
cardiac death.

Although the evidence is less clear for other conditions, researchers
are studying the anti-inflammatory benefits of omega-3s for rheumatoid
arthritis, ulcerative colitis, Crohn's disease, lupus, and even
menstrual cramps. Fish oil has been found promising in patients with
asthma, cystic fibrosis, osteoporosis, and depression as well.

Personally, the quote from "The Health Professionals Follow up Study"
could easily be a couple doctors that work for this supplier, but I
haven't checked deeper. My Onc says there would be no difference in
life expectancy. I go by "it can't hurt"

Fred,

There is a pretty good explanation of this in one of Dr. Charles Myers
nerwsletters at http://www.prostateforum.com/backissues.htm. If you
look at Vol. 8 Number 7, he discusses the advantages of Omega 3's. But,
he warns it is best to get it from fish and NOT from flax. Flax can
cause problems for those of us with PCa.
