Please tell your girlfriend to look into a fruit called Guanábana which comes from the Graviola Tree in the Amazonas. Its supposed to be 10,000 more potent than chemotherapy and only targets cancer cells. She may not even need a masectomy. Someone sent me this info (in Spanish) but here´s the website the info was from: http://www.hsibaltimore.com
and the info there is in english.
Here´s wishing good health to you both!
