Ut for cancer

Urotherapy is suggested as a new kind of immunotherapy for
cancer patients. Unlike the clonal immunotherapy the urine
of the cancer patients contain the many tumor antigens which
constitute the tumor. Oral auto-urotherapy will provide the
intestinal lymphatic system the tumor antigens against which
they may produce antibodies due to non-self recognition.
These antibodies may be transpierced through the blood
stream and attack the tumor and its cells.
