Soy and Organic Green Tea?

[1S2M3S]

I am new and thanks for these informative posts. After 6 years clear of Stage 1 breast cancer, I have metastatic breast cancer in my bones, none in lymph nodes. I have no pain and I have been on Ibrance 125 three weeks on, one week off And Letrozole 25 daily for a year. All good with monthly blood labs, “within normal for me on these meds” , and every 4 months FDG -PET scans show no progression. “You are doing great”, at my monthly oncologist appointments now pushed to every six weeks. My only side effects are some fatigue in the afternoon and constipation ( but under control). So far so good! My question is about having a small amount of Soy found in some foods and drinking Organic Green Tea. My oncologist doesn’t say yay or nay to supplements so I research and check before starting anything new. I appreciate any information not just your opinion but what you have learned. Thanks and best wishes to others
