I cannot give you a definative answer on flax. I only "research" at the start interest for my own interest, then out of a need to understand, and then a need to try and communicate the potential importance of what I had read particularly omega three six and digestive health which I am now trying to put together to see if it might make a book.
From the differing views on flax it is obviously a hotly debated issue. Oncs are very busy and may not have time to keep up with changing debates, and I dont know on what grounds the advice was given so am no position overall to comment on a particular oncs views.
I suggest that you print out the attached posts and ask your onc what they think of the various arguments made - you never know they might be pleased to be given information they have not seen before or may be able to come back with more knowledge to add to the board.
I hope this helps.

I have titled it as "flax seed summary rb" to try and make it easier to find again by search if it is needed.
