Answer 1

If you have cancer, it mean that you have genetics defect that your healthy cells will easily give rise to cancer again. “Cancer free” means that we had killed all abnormal cells that doing harm to you. But a lot of cancer progenitor exist in a state that indistinguishable from healthy stem cells, when these cell divides, one copy remain perfects but the other one has a slight defect that will eventually turn into tumor.
