Which diseаse is described here? Eаch time this diseаse arises it is an independent evоlutiоnary prоcess in which multiple clones of cells originate through mutation and then compete with each other for resources. Clonal competition fed by genetic heterogeneity among cell clones drives natural selection that favours the better performing clones. Here performance significantly includes both the ability of cells to spread and invade other tissues and the resistance of some clones to chemotherapy. Thus two of the most significant characteristics of this disease are products of natural selection.
