Unproven methods of cancer management. Gerson method of treatment for cancer.

The American Cancer Society's own contemporaneous (1973) committee statement on the Gerson method, part of its long-running 'Unproven Methods of Cancer Management' series. Both the PMID and DOI verified directly (PubMed and Crossref/DOI resolver). Full text was paywalled (Wiley returned HTTP 403 to direct fetch), so this is cited for its confirmed bibliographic existence and its role (per secondary citation in Wikipedia, MSKCC, and CAM-Cancer, which independently and consistently describe it as finding no evidence of benefit) rather than for a verbatim quotation from the paper itself.
