Diet for breast cancer

@resort The type of cancer we seek to prevent from recurring may influence diet. I had HR+, HER2- BC and my oncologist told me to avoid foods with plant estrogen. I researched flax seed, tofu, beans, etc. and the recommendation is to avoid these because while these foods help prevent some cancers, they help stimulate recurrence of others, such as the BC I had. Consequently I stopped eating flax seed. I do feel somewhat stymied over the exhortations to eat healthy AND avoid certain healthy foods: what can I eat that helps more than hurts?
