Hugs. I totally understand why you don't want to have treatment. I too am a big believer in alternate healing and organic food, etc, I consider them part and parcel of my treatment plan, not instead of my chemo.
That said the decision is yours to make, but I would encourage you to be treated with arimidex. All cancer drugs have lists and lists of horrific side effects, but that does not mean you will get any or all of them, or how sever you will have them.
