Liver Flushes most definately because they help to clear the lymphatic system.
An effective natural progesterone cream is a must as well (Arbonne has one of the best ones out there, take your chances with what's avail at the health food stores - go to www.arbonne.com - can use my id #10321274 if you like or order under someone else - just get her using some!)
Dr. Zava a leading authority on natural progesterones says that 90% of Breast Cancer could be avoided if women got their progesterone up to normal levels (which means supplementing with nat. prog cream in most cases.) There was an article last year in Mirabella magazine that stated that women who used nat prog cream after masectomies had no recurrance of breast cancer.
My whole life I had very fibrocystic breasts - had done lots of cleansing, healthy diet, etc. but nothing worked until I started using the natural progesterone cream from Arbonne. Have tried many different brands and always come back to the Arbonne product because it's the only one that works! Have had many friends and cliens have the same experience. Also really good for any female maladies such as hot flashes, pms, etc.
Definately have her do the lv/gb flushing too because the liver is key for getting the hormones in balance. Lumps like that in the breast are a serious matter - on the road to breast cancer. She doesn't want to mess around, but get them reversed as soon as possible.
