I am so sorry to hear of your wife's (and your's for her) suffering. If you have been growing wheatgrass for 9 years did she drink the fresh juice before she was diagnosed with cancer, after? You say that you are different and she goes with the doctors, so did she not every try the wheatgrass before or after her diagnosis and treatment? My husband was told two weeks ago that he had a malignant tumor in his throat. They scheduled the biopsy, staged it and set up the radiation treatments because the doctor was certain it was cancer. Though I had told him many times if I am diagnosed with cancer I will go natural not chemo or radiation, and follow Dr. Day's health plan, and shared good information with him, he agreed to the radiation. We are thankful that when the doctor did the surgery he found a polyp and took it but he is agreeing to try the juicing. We are doing carrot and apple, and I add greens to mine. Today I juiced just six or so blades (halfed) in mine. I don't feel any purging symptoms yet. I am hesitant to juice too much at first. He has agreed to try Barleygreen powder in his juice, but it hasn't arrived.
