Soy and flax in relation to ER+ breast cancer?


Question from julie: What is the thought now on soy/flax intake in estrogen-receptor-positive breast cancers?
Answers - Eric Winer, M.D. I always tell patients the same thing about this: they should eat foods that they enjoy, and that provide good nourishment. I do not believe that women need to either increase or decrease their consumption of either soy or flax to prevent a recurrence of cancer since we do not have data to support such a recommendation. I think concentrated soy products are foods, so I don't think people should eat them as a medicine. If someone wants to drink soymilk, that's OK with me.
Marisa Weiss Soy foods such as soy milk, tofu, edamame, etc. can be a healthy part of your diet if you enjoy them, but I have concerns about people using pharmaceutically concentrated soy products beyond what they're taking for nutritional needs. We just don't know the safety when you load up on these items.
