M.P.
You should go to this site and ask your question on the alternative medicine board. http://community.breastcancer.org/
This site will be very helpful to you and your mother as you navigate this. I had BC last year and this was the only source of information that I used online.
I am glad that she is booked for surgery and not depending only on these pills. People that do this kind of thing only unfortunately do not have very good results. Natural is good in conjcuntion with traditional medicine when it comes to cancer.
Good luck to her.
