Help mom fight cancer

My mom went in for a hysterectomy because the doctors thought she had ovarian cancer. It all happened so fast. She was told the week prior she would need surgery. She went in and they found that she didn't have ovarian cancer, she has colon cancer and it had spread to her ovaries. It is stage 4 level 2 cancer. My mom is only 52! I believe God has directed me to the Gerson Therapy. In researching alternative treatment, this seems like the best route. It focuses on flooding your body with produce through juicing and riding it of toxins. I was introduce to it two weeks ago before having any knowledge of mom having cancer. God is divine! It is expensive but I truly believe with prayers and this treatment it will cure her.  However this is only one path she may take. We want her to have any options she can to beat this thing! She is so strong and I know she will! Thank you all in advance.
