When my husband was diagnosed with cancer, "A Cancer Battle Plan" was one of the first of many books on cancer that I read. I was so uplifted by Anne's healing. It is truly an unreal story. Unfortunately, I was very sad when I learned she had died about 10 years after her battle.
In the late 1990’s, after many years of recovered health during which HealthQuarters Ministries took root and began to flourish, Anne did eventually run away with Jesus. Troublesome symptoms, for which the Frahm’s received no adequate answers from health care professionals they sought out, were part of her last months. A postmortem autopsy showed that iron poisoning, due to the nearly 200 blood transfusions she’d had as part of the original cancer therapy, had shut down her liver.
It is suggested that you do not fast if you have cancer. Why? Most all cancer patients are nutrient deficient and need dense nutrition. After you start to recover, rebuild your body, I would recommend it.
Joel Fuhrman who wrote the book "Fasting and Eating for Health" does not recommend fasting if you have cancer.
Edit: In Jordon Rubin's book "The Great Physician's RX for Cancer," he recommends a 3 day juice fast. He then recommends eating dense nutrition.
