To treat cancer: consume NO red meat or alcohol, take zinc (recommended daily allowance) & pancreatic enzymes (fresh pineapple & papaya abounds in natural enzymes) . Take a *****-analysis pregnancy test upon rising (a full urinary bladder is best). Positive means: pregnancy or cancer or pregnancy plus cancer or false positive (the kits are only a dollar). If 4 of 6 tests are positive (for men too) then cancerous/tumorous activity is present. The B17 will stop the process. Initially tumors will swell as malignant cells die. In time the tumors will shrink by no more than 5 to 10%. You'll be cancer-free but NOT tumor-free. If the tumor is impinging nerves or blood vessels (or for cosmetic reasons) then surgical ablation might be warranted. Otherwise, in time (it may take years) the benignant tissue will be absorbed

Additionally: To treat cancer, patients have taken up to 6 grams daily in pill/capsule form and even more intravenously. ALL B vitamins are water soluble and will turn one's ***** orange.
