Allergies probably don't protect you from cancer. I help people cure their cancer, so far at 100% success. I know the causes and they are unexpected shocks or traumas. I have even helped patients over the telephone as far away as South America. No needles, drugs, herbs, fasting, or special diets.
Every type of shock has a very specific type of corresponding cancer. If the emotional issues at the root of cancer can be resolved the cancer will go into remission.
A German oncologist made the discovery, Dr. Hamer.
