Hello, I wonder if you could answer question for me. I was diagnosed with triple positive breast cancer in July last year. Lumpectomy chemo/herceptin and radiotherapy sessions followed. Still on my year of herceptin injections. I have been taken off all HRT and begun letrozole. Menopause symptoms are back 
. I have read soya and other isoflavins are very good helping this. Is it safe to eat these foods as they are plant estrogen? Many thanks. Kate
