Hi Cobie
Hope you are well, I have just been to a breast cancer talk on nutrition at the Mater Hospital in Sydney. It was excellent and dispels a lot of myths including the dairy food one. I too am hormone receptor positive. The talk was by Dr Susan Hart (herself a breast cancer survivor) and she has written a book on this which should be released in about January 2014. I also went to a BCNA forum where her new book was also discussed. I am certainly going to buy it and what I got out of her talk was to eat a sensible normal balanced diet.
Hope this helps
Fiona
