View Full Version : The impact of Omega 3 and Omega 6 on breast cancer
There is a long running thread on the impact of Omega 3 and Omega 6 on breast cancer on the main board.
Many of the factors also apply to a whole range of cancers including prostate.
The thread only contains a fraction of the research on the subject.
The revised expanded and improved book on Omega 3 and 6 is currently being edited and now has approaching 2000 references.
On the tooth issue, on my persistent insistence that something was still not right, they finally opened an adjacent area up (Nov 2009) and found further infected bone above another root filling (2nd), despite showing no "clinical" symptoms (inflammation or pain) or clear x-ray evidence, but discomfort from my perspective. It now looks in addition as if my 3rd and last root filling may also have lead to infection (in progress).
Moral: As far as root fillings go get them checked regularly. I now know trials confirm a significant proportion of root fillings fail within in 5 years. (-:
This is the latest post.
"This is a useful paper on the role of Omega 3 and 6 in cancers. The whole paper is on the web for free.
It is well worth a skim just looking for Omega 3 and 6 comments, even if you have difficulty with some of the rest.
FIG 5 cleverly and simply visually explains the Omega 3:6 imbalance clearly
"The results of animal studies have demonstrated that the
consumption of omega-3 fatty acids can slow the growth of
cancer xenografts, increase the efficacy of chemotherapy and
reduce the side effects of the chemotherapy or of the cancer"

Evidence Omega 3 DHA may improve the outcome of some chemotherapies.
I have also posted this on the main thread.
Improving outcome of chemotherapy of metastatic breast cancer by docosahexaenoic acid: a phase II trial
P Bougnoux,1,2* N Hajjaji,1,2 M N Ferrasson,1,2 B Giraudeau,3 C Couet,1,4 and O Le Floch1,2
"Several research groups, including ours, have shown that docosahexaenoic acid (DHA), a lipid of marine algal origin mainly provided by diet, has, experimentally, the ability to increase the efficacy of anti-cancer agents."
"As DHA incorporates into cell membranes, this differential handling of ROS may account for the selectivity of DHA-induced tissue sensitisation by anti-cancer agents in tumour tissues compared with non-tumour tissues. Along this line, the lack of additional toxicity in non-tumour tissues has been consistently documented under conditions in which tumour tissue DHA was sensitised to chemotherapy (Hardman et al, 1999; Kato et al, 2002; Germain et al, 2003; Xue et al, 2007) or radiation therapy (Wen et al, 2003) in rodents.
On the basis of these results, we conducted a pilot phase II clinical trial in metastatic breast cancer patients to investigate the efficacy and safety of adding DHA to an ROS-generating chemotherapy regimen, that is an anthracycline-based regimen (FEC). We found that the combination was safe while retaining significant anti-tumour activity in the sub-population of patients with high plasma DHA incorporation, suggesting that DHA has a potential to specifically chemosensitise tumours."

Here's a new omega 3 study just from today. States that the reason Omega 3 helps cardiovascularly is that it reduces aging (shortening of the telomeres) and as such, there is more accurate genetic replication (ie: could help prevent cancer as inaccurate replication starts the process)

So how much of Omega-3s should breast cancer patients consume on a daily basis? I'm now wondering if I should add a supplement to my diet and how much of it I should take. I'd check the threads you posted above for some guidelines.
Thanks for bringing these to our attention!

I believe that 1-2 grams of DHA should be consumed (therefore, depending on how much DHA is in the brand of fish oil you purchase could be 6-8 capsules a day). I take this much but cut back on days I am eating fatty fish as it is abundant there. I also don't freak out if I forget a dose (as I divide my supplements up during the the 3 meals of the day taking 2 fish oil capsules with every meal).
You should be careful with other supplements that are also blood thinners (aspirin therapy and look at your other herbals - for example, when I first got my ooph almost 5 yrs ago, I had bladder infections alot and took cranberry extract (also a blood thinner) and watched carefully how much of other things I was taking. I no longer take cranberry but have it around just in case.
You do have to be careful on potential side effects of these things because if you take alot of stuff that has the same side effect, you can get slammed.
You also need to let your doctors know what you are doing and have them on your "prescription list" that you carry just in case you land in the emergency room for something - they know what you are on.
PS - Of all the supplements that can be taken I am a true believer of 2. One is Omega 3 supplementation and the other is Vitamin D (we need more than the gov'ts 200-400iu per day. We need much, much more - more in the range of 3000iu to 5000iu per day). These are the super supplements to me. If I only could pick 2 these would be them. If I could only pick 1 it would be omega 3 and I would start a tanning regime to get the Vitamin D!

I am in total agreement with you in regards to the 2 most important supplements. I am a firm believer in "Food First" because in many cases the synergy of food cannot be replicated in supplement form. That has been proven time and time again in research. Individual nutrients in cell line studies often demonstrate benefit but rarely replicated in human studies (or at least very difficult to prove). Unless a person has perfected their diet there need be little focus on supplementation, EXCEPT for Vit D and Omega 3s. Both are very difficult to achieve adequate dose in food and both extremely important in cancer and overall health and wellness. You are wise to provide caution in regards to the blood thinning. Thank you.

It sure would be nice if one the supplement companies would produce a combo Vit.D3 and Omega 3 capsule for us. All these pills we take are sometimes hard to keep track.

WebMD has a full article on Omega 3 today. Thought I'd attach the link here:
It is wonderful to see the concept of balancing the Omega 3s and 6s gaining more acceptance.
Some of the other info could be better put. In particular plant based oils can be converted to the long chain fats, but many people are not very good at it. Evidence is emerging some population groups - Celts fair haired blue eyed redheads, Innuit, and others who were maybe shoreline dwellers - are possibly genetically at risk of being maybe 30% less good at conversion. Many common dietary factors and deficiencies also significantly inhibit conversion. Some health conditions like diabetes inhibit conversion. Some viruses can affect conversion. As a result you cannot automatically assume an intake of plant based Omega 3 will end up being made into the EPA and DHA you need.
Also if you select fish at low risk of mercury pollution you can safely eat much more than 2 portions a week. The benefits far outweigh the risks.
Women can make more EPA and DHA because they need it for all sorts of reasons, including supporting a more sophisticated brain and nervous system, which endows them amongst other things with better sensory perception. Women can convert plant based Omega 3 to EPA and DHA 10 times better than men likely because of oestrogen. This would be another reason why those who are low in oestrogen should ensure they get adequate DHA and EPA as well as the plant based Omega 3.

A follow-up article posted today on WebMD:
^ Thanks Jackie
That is a very useful article and addresses many of the issues I raised. It would be nice if the next article looked at some of the functional differences between the short and long chain fats. (-: Maroon and Bost's book "Fish Oil The Natural AntiInflammatory" is very helpful, and gives a doctor's perspective. Maroon at the time the book was written was Vice-Chairman of the Dept of Neurosurgery at the University of Pittsburgh, and neurosurgeon to the Pittsburgh Steelers. Bost worked in the same field and department.
I have added some new material (-: to the link
There are new links on the main thread since I last bumped the thread. (-:

WebMD's new slide show on Omega 3 foods:
It is great news that the US army is starting to look seriously at the Omega 3:6 issue.
They have a real ability to make things happen, the economic clout to change company food production methods, and a massive educational ability.
Joe Hibbeln is a very articulate persuasive intelligent motivated respected specialist in the field at the NIH, who has taken the Omega 3:6 issue / wider nutrition to the US military and persuaded them to look at it seriously.

Informative post, link and thread on the impact of Omega 3 and Omega 6 on breast cancer and agree with you as Omega 3 and Omega 6 reduce the risk of breast cancer and other health issues also by improving immunity system so we must add Omega 3 and Omega 6 in our daily meals for a healthy life.
