Admittedly, the results in cases where patients had received prior chemotherapy were sharply reduced compared to those who received no such toxic drugs. But, in many cases, we were still able to obtain recoveries. We did find out, however, that certain cancers do not respond after chemotherapy. Pancreatic cancer, which shows excellent results on the Gerson Therapy, does not respond after the patient had received chemotherapy. Leukemias, after heavy chemotherapy, are also difficult to reverse with the Gerson Therapy.
Brain tumors fall into the same category.
Melanomas, which usually respond exceptionally well to the Gerson Therapy, do relatively poorly after chemotherapy. Of course, all types of cancer respond much better with no prior toxic drug treatments. The problem for a researcher is to prove this statement. Unfortunately, there are no true tests for toxicity in the system. I personally feel that the remaining toxic drugs could be lodged in the connective or fatty tissues.
