Hi
I posted some of this on another thread but it applies equally here.
HOW MUCH EPA AND DHA.
There are no absolute answers. Flori is taking about 1.5 grams of EPA and DHA a day which is about the maximum that is accepted as not posing any serious risk for most people.
There is a trial that shows the uptake in women dropping off at about 2 grams of DHA a day so 1.5grams is getting towards what may be the maximum.
If you have digestive problems then the Omega 3 may not be being digested which is an argument for not taking say 200mg a day.
But talk to your doctor and do not take this level of fish oil / DHA EPA before that if you are on blood thinners medication etc.
VEGETARIAN OR BLOCKED CONVERSION
You cannot assume that you are able to convert the plant omega 3s to DHA and EPA. Lots of things can block that pathway. Loss of oestrogen function results in the conversion ability dropping significantly.
There are sources of EPA and DHA for vegetarians (although algae are strictly living in a sense).
TUNA - The longer liver the fish the greater the amount of contaminants including mercury. There are concerns about tuna consumption with varying recommendations as to the maximum to eat a week from 1 - 3 portions.

Small oily fish are better and have more long chain Omega 3s - Atlantic mackerel, sardines etc.
REDUCE OMEGA 6 INTAKE.
Many trials suggest higher Omega 6 contributes to the risk of BC.

We only need about 1% - 2% of calories of the plant based Omega Six, and some suggest the figure is as low as 1/2%. ISSFAL the International Society for the Study of Fatty Acids and Lipids suggests a maximum of 3%.
Most have an intake of 10% or above.
For me that needs to be balanced with the plant based Omega 3 on the basis that there is generally more Omega 3 than 6 in green things which is where the food chain starts.
Seasonally we we have got some seeds and nuts which are high in Omega 6 which would have pushed the balance back towards Omega 6.
If evolved by the shore by accident or design we would always have had access to marine foods which are generally much higher in long chain Omega 3s than 6, which is why it is fine to get more long chain 3 than 6 ( as well as being shown to be beneficial in lots of trials for a variety of illnesses)
FLAXSEED
Flax seed may be of benefit, but a subject of much discussion so please talk to your onc and show him or her the trial.
Here is a trial link

"Our study is small and the results need to be confirmed in a larger number of patients for a longer treatment period before it can be definitively concluded that flaxseed has the potential to reduce the growth and invasiveness of breast cancer. Its excellent tolerability, however, may make flaxseed particularly attractive for studies in breast cancer prevention, where healthy women should be offered well-tolerated interventions for long-term use. The interaction of flaxseed and its lignan and oil components with other hormonally active agents also needs to be addressed in the future. If the therapeutic index seen in this short-term study can be sustained over a long-term period, flaxseed, which is inexpensive and readily available, may be a potential dietary alternative or adjunct to currently used breast cancer drugs."
FLAXSEED AND IODINE.
Flaxseed blocks iodine uptake to a certain extent, so please make sure you are getting adequate iodine.
MINERALS
Mineral are important to the processing of fats. So please make sure you get adequate minerals to. Fish and shell fish are good sources of various minerals, which you will not get in oil.
