During the emergence of cancer, a mutant cell can develop its own subpopulation and  progressively invade the resident population.  We start from a single mutant cell with an almost zero initial fitness. The goal of this work is to examine how a single mutant cell evolves and expands, from its first appearance to the point where the tumor becomes observable at the macroscopic scale.  We formally identify three distinct regimes from the microscopic scale to the macroscopic one.
