Cancer remains a frightening and largely incurable disease. The toxic side effects of chemotherapy and radiation make the cure often seem as bad as the ailment, and there is also the threat of recurrence and tumor spread. Cancer treatment still follows a practically medieval method of cut, burn or poison. If the growth can’t be cut out through surgery, it may be burnt away with radiation or poisoned by chemotherapy. As a result, cancer therapy remains a daunting diagnosis for patients and treatment options seem limited for a disease which causes one in six deaths globally. The failure to innovate in cancer treatment may lie in the very poor success rate of clinical trials.
