    Excessive soy intake and soy supplements can have a moderately high level of estrogen like activity. Ordinary dietary intake of moderate amounts of soy are not likely to cause a problem for a person who has had complete therapy for breast cancer and is not undergoing therapy for aggressive disease. If you are on tamoxifen or other anti estrogen medications it would be best to keep a record of your usual soy intake and discuss that with your oncologist at your next visit.

    I recently attended a seminar while at the Living with Breast Cancer Conf. in Mpls. The nutritionist, Jeff Woodward, said that those with estrogen receptor positive breast cancer should limit soy intake, definitely no soy milk or soy protein supplements, and limit edamame, etc. Almond or rice milk are good alternatives...one can also make a cashew milk for soups and sauces.

    I am a survivor and blogger, diagnosed with a hormone-positive locally advanced breast cancer in l998. At the time information on soy was confusing and made no distinction between hormone fueled cancer and menopausal status, not to mentioned medications. While many encouraged me to go "soy," I did not and would not recommend this. My best advice is to maintain a healthy weight through exercise and an "anticancer" diet, rich with vegetables, fruit, grains, and lean protein. I also encourage all survivors to meet with a registered dietitian (one who isn't selling supplements) if you have additional questions.

    A wonderful cookbook I just received from the American Institute for Cancer Research is "The New American Plate."

    I'm going to go with Dr. McGlone on this one. My oncologist said that it's OK for me to have soy products, and I was estrogen-positive. I think anything in excess can cause health problems. I do agree that a healthy diet is essential, but I don't believe any diet can totally prevent cancer.

    I have to agree with both Jody and Beth's statements. Most importantly, never go to a dietician who is trying to sell you the supplements they recommend are "best for you" or "designed for your particular diagnosis". They often end up being the modern equivalent of the snake oil sales people. Go to qualified and certified dieticians and ask the pertinent questions that matter to you and your dietary habits.

    A recent study shows "Soy intake may reduce breast cancer recurrence". A diet high in certain soy compounds, called soy isoflavones, may reduce the risk of breast cancer recurrence among survivors of some types of breast cancer, according to new research. Researchers found post-menopausal breast cancer survivors in the study who consumed the most soy isoflavones, around 42.3 milligrams a day, had a considerably decreased risk of recurrence of their breast cancer compared with those who consumed the least, around 15.2 mg a day.

    I am a breast cancer survivor (estrogen positive) and blogger who certainly believes in the benefits of a healthy diet. I don't think one needs to eliminate a particular food group, like soy or dairy. Avoiding excess is always good advice. My oncologist has not spoken to me about diet at all. Perhaps I should ask about that at my next appointment. Also, I think we have to be careful not to make women feel guilty about what may have caused their cancer, some cannot be prevented. Mine was caused by the BRCA 2 mutation. Just try to eat as healthy as possible, exercise and maintain a proper weight.

    Hi Nancy,

    Glad to see you on Medpedia!! Nancy is an excellent blogger. I think there are so many food extremists out there, and it's good to eat sensibly -- things in moderation. I'm with Nancy on this.

    I had a healthy diet, was physically fit, and did all the "right" things, and I still got breast cancer. There are so many factors that can play a role in a developing cancer. And Nancy is right: women really are often made to feel guilty in the media and through society that it is something they did or did not do that caused their cancer.
