Why is SPDT/SDT a new ball game?
Because it kills cancer without longer term damage. This makes it highly acceptable to patients, and it can be repeated as necessary. Conventional cancer therapies may well be effective, but treatment may be limited by long term damage, and the therapy may ultimately fail. Surgery – is often very effective, but cannot be repeated very often. Each time the patient loses healthy tissue. Radiation therapy – is damaging, and patients have a maximum lifetime dose. Chemotherapy – the body usually builds up resistance to chemotherapy. Different drugs can be used, usually with increasing toxicity and decreasing tolerance by both the body and the patient. Even if initially effective, chemotherapy may (after a while) cease to be effective. Another factor is that patients may get fed up with damaging therapies, even if they are effective, and they give up. With SPDT/SDT however, there is no evidence of long term damage, and no evidence that it loses effectiveness.
