    "problem_addressed": "Cancer presumed to be caused by a specific bacterium (Progenitor cryptocides); lack of effective immunotherapeutic treatments.",
    "concept_summary": "Livingston's therapy involves isolating bacteria from a cancer patient's urine and blood, culturing them, and preparing an autogenous (patient-specific) vaccine intended to provoke an immune response against the tumor.",
    "detailed_description": "The method extracts bacterial isolates from tumor-related bodily fluids, grows them in culture, and formulates an injectable vaccine. The vaccine is not an anti-cancer drug per se but an immunomodulator meant to enhance host immunity. The approach was patented (US 4692412) and administered at the Livingston-Wheeler Clinic, but it has never been validated by mainstream clinical trials.",
