Patti, I got all that stuff on the advice of my girlfriend who is a doctor herself and a survivor of stage 4 breast cancer. She has been taking it during chemo.
She was taking it along with chemo and radiation. She is cancer free now, but she was young, which helped fighting cancer, and I am not))
I do not have an opinion since I just got diagnosed and running around collecting tests and all that. Trying to keep myself together and living one day at a time.
