So after reading what your saying Sirtex mode of operation is to destroy the blood supply feeding the cancer ? Oncosil is to alter or destroy the DNA of the cancer thus making it vulnerable to the patients own immune system ? If the second senario is true about Oncosil device they might be better of not using Chemo at all as it weakens the immune system . I have a substantial holding in Qbiotics in Qld they are developing a drug EBC 46 that has a mode of operation that does both of these without using Chemo . The main reason the human immune system struggles to fight cancer is because your white blood cells do not recognise the cancer as a threat because the cancer cells have your DNA . Alter the DNA of the cancer itself and your immune systems response is to attack and destroy the vascular system feeding the cancer which in turn completely kills the cancer in its tracks
