A bioelectronic medical method and system for rapidly destroying living cancer cells and the tumors they create including metastatic off-spring of such tumor(s) regardless of their location within a human or animal body. Calcium ions can be inserted into a nucleus of a cancer cell(s). The nucleus of the cancer cell(s) is then fragmented among many cancer cells (e.g., in a tumor) simultaneously with the transmission of a destructive analog electrically encoded signals to provide a medical cancer treatment thereof. A first target of medical cancer treatment is aimed principally into the nucleus and mitochondrion bodies of a malignancy associated with the cancer cell(s).
