Will biologic therapy 'cure' cancer?

Curing cancer means that all the cancer that you see goes away number 1. That's called a complete remission where you can't see any more cancer and number 2, it stays away and certain cancers have different periods of vulnerability for when they come back. Breast cancer, for instance, everyone is encouraged as they should be when it stays away for two years or five years, however, breast cancer comes back much later in a small minority of patients. Lymphomas tend to come back earlier. They are fast growing cancers as do leukaemia's. So at a two-year or five-year mark, they may be considered cured. So biologic agents, because they kill cancer cells especially in conjunction with chemotherapy can indeed be part of the cure. It appears that you can with either chemotherapy or biologic agents kill enough cancer cells so that the immune system takes over and can clean up the rest. That, in essence, is how cancer is cured.
