Fish Oils May Encourage Prostate Cancer

Fri Jul 12, 2013 3:39 pm

If it isn't one thing, it's another.

Study finds link between fish oil and higher prostate cancer risk

Quote:
A new study is raising questions about omega-3 fatty acids, which are found in oily fish and fish supplements, suggesting that men with high levels of the oils in their bloods might also have a higher risk of prostate cancer.

Omega-3 fatty acids have long been hailed for their apparent ability to lower blood pressure and cholesterol and perhaps protect against heart disease. They’ve also thought to have anti-inflammatory properties that might help prevent a number of forms of cancer.

But a new study has found that men with prostate cancer were more likely to have higher levels of omega-3 fatty acids in their blood than similar men without prostate cancer.

Eating a balanced diet without trying to induce higher than necessary levels of one supplement or another continues to look like the best approach.

That doesn't make me anti-vitamins—I take a B-12 tablet since it's been proven through medical tests that I don't digest B-12 properly, and the occasional iron tablet since I run a bit anemic naturally—but the more I read the more I'm glad I didn't jump on the whole mega-vitamin and supplement craze.

I agree, I believe no amount of extra vitamins and other supplements can ever compensate for lack of healthy and balanced diet and receiving unnatural amounts of some supplements can surely have a negative effect too.

Really the only supplement I find necessary for me to take is vitamin D, officials recommend everyone to take extra Vitamin D supplements during winter around here as the amount of sunlight is too low to help generating it enough and average Finnish diet doesn't give enough of it either.

Tried to take some Omega 3 stuff during winter, didn't feel any different so I don't bother anymore.

Well - if I didn't take 4,000mg of prescription purity fish oil daily - my triglycerides would be over 1,000.

I wouldn't live long enough to have prostate cancer as a possibility.

Been doing that for 12 years since high triglycerides shut down and badly damaged my pancreas, and danged near killed me.

Smoking reduces the risk of uterine cancer. True story.

When I get uterine cancer, I just stop getting uterine cancer and be awesome. True story.

Also, one issue with this article. It showed higher levels of omega-3 fatty acids in the blood. It did NOT correlate to omega-3 fatty acid intake.

Now, this is important. When a study like this is done, it raises scientific questions.

Perhaps prostate cancer patients have tissues that are less likely to take up omega-3 fatty acids in the blood, which is why they have higher blood levels. In this case, omega-3 fatty acid supplementation might actually reduce the risk of prostate cancer. And, in fact, other studies have found a negative correlation between intake and risk of death from prostate cancer. So mine would be a hypothesis that supports both findings.

I raise this not necessarily because I think my hypothesis is correct (although perhaps it could be), but because I want to educate people about how scientists think about these things.

You cannot jump to the conclusion that omega-3's cause prostate cancer and so we should all stop eating fish.

Wouldn't you be better off taking prescribed statin such as Lipitor or similar? It has worked amazingly well for my family.

Hey. My mom had uterine cancer.

Well, she got it 20 years after she quit smoking, so I guess you have a point.

However, the main risk factors for the uterine cancer, according the gynecologic cancer foundation's website, are a) childlessness, b) obesity, and 3) taking estrogen without also taking something that I believe is called a progestin. (Are there amateur gestins?)

Don't know anything of my mom's hormone regimen, but she fat, so there's one likely culprit.

Now. I myself take 3,600mg of the fish oil daily (1 1200mg capsule... oh what is that medical abbreviation for 3x a day... is it t.i.d.?) so I am not happy to hear of this alleged risk o' cancer. Without my fish oil I am a disaster; not paying my bills on time, not working hard at my job... no sir, I require this fish oil stuff for brain health. My PSA count was 1.57 when my blood work came back a month ago; according to what I've read that is spang yes SPANG in the healthy range.

Thus I have conclusively disproven the fish oil = prostate probz hypothesis. 



At the bottom of my screen right now is a link to a thread called "Eating Pizza May Lower Risk Of Cancer."

I am sooooooo on it.

After cataract surgery, an eye specialist advocated fish oil to me. When I visited him for check ups, he kept asking if I was taking it. Four or 5 days ago, I finally took some, after waiting four months. Now this. That is it for the fish oil for me. A couple of my friends are being treated for prostrate cancer, and after seeing what they went through after radiation therapy, no thanks.

I take Lipitor (generic) for cholesterol, and Naispan (2,000 mg) and the prescription fish oil (4,000 mg) for triglycerides.

It is a combination that has worked very well, along with a rabbit food diet and steady exercies, for several years to control those, and no cause problems with my diabetes induced by the damage to the pancreas.

No. A sample size of 1 means nothing. George Burns smoked like a chimney and lived to 100. That doesn't prove that smoking is salubrious, it just proves that George Burns was lucky.

Did you read my post? There are studies that show a negative correlation between fish consumption (which is something you can directly modify) and prostate cancer. This study correlated blood omega-3 levels (which you cannot directly modify) to prostate cancer.

How many Americans die of vascular disease every year? How many die of prostate cancer? I'll take my chances with the fish oil, given the available evidence at the moment.

I did, but I feel that I have gone without eating any fish, not taking any fish oil all of my life, so why take a chance at my age. I was only speaking for myself of course. I advised my wife to keep taking it. I do not think she has a prostrate problem, nor will she.

The person whom we who study toxicology call the father of our profession said:

"Alle Ding' sind Gift, und nichts ohn' Gift; allein die Dosis macht, daß ein Ding kein Gift ist." which we translate to "All things are poison, and nothing is without poison; only the dose permits something not to be poisonous."

But there are a lot of studies being done on the relationship between fatty acids and tumorigenesis in different parts of the body (especially in the digestive tract. IT is going to get very interesting.

I'm kinda doing it backwards - I started using Mega Red 8 years after I had my prostate had been cut out. After the surgery, radiation that followed and 8 years of a 0.0 PSA I feel fairly comfortable that I'm safe. The Kidney Cancer (clear cell) that was removed this past January is my current issue to follow with concern - if it goes tot the lungs there is title help to cure it.

My triglycerides are high and I take Slow Niacin (Vitamin D) to help keep it in check. Cheaper than a Rx.

I wonder if those subjects were pre-disposed to prostate cancer? My doctor worried at first about my heart health risk but found out that my father and grandfather both were heavy smokers and had poor diets and that I exercise and eat well and does not worry so much.

I wouldn't lose sleep over the findings of one study. Lately I've had patients asking me about cooking with coconut oil due to its proposed and now heavily marketed "anti-cancer and antioxidant properties." What they fail to mention is the high amount if saturated fats will cause heart disease much sooner than any anti-cancer benefit would be seen.

A high omega 3 diet is the diet humans evolved to live upon though. Modern diets have a completely out of what omega 3 to 6 ratio.

No point worrying about anecdotal cancer links. You've gotta die eventually.

In any case, if this were so, prostate cancer rates would be sky-high in Japan, Taiwan, Norway, and other nations with high levels of fish consumption. And they aren't.
