The relationship of diet in preventing and treating cancer has been extensively studied. The importance of diet is particularly true for breast cancer where the findings are unambiguous and the magnitude of dietary influences is enormous.
A brief summary of what is known:
There is a strong relationship between development, progression, recurrence of breast cancer and-
Excess body weight
Alcohol consumption
Animal (not vegetable) proteins
Cholesterol
Strong protective effect-
Soy- tofu and soy milk but not fermented products like tempeh and miso (which are healthy but not important in breast cancer); concentrated soy or isolated soy protein may be harmful
Mushrooms- all, especially button
Flaxseeds, especially ground
Vegetables and fruits in general

Glad you like it, Mike. Same things are true for prostate cancer but soy effect is less.
Peace

I always ground up flaxseed for my horses. Most seeds can’t be broken down by humans but can be by animals, from what my research tells me.
From my research, there are many foods that need to be prepared a certain way in order for humans to reap the benefits, such as sprouted nuts. I wondered the same thing about how mushrooms are prepared.

All mushrooms have some toxin. If it’s a lot they are poisonous. Edible mushrooms are always healthier if cooked enough to destroy their toxins.
