Context-dependent selection as the keystone in the somatic evolution of cancer.

Abstract excerpt

Somatic evolution of cancer involves a series of mutations, and attendant changes, in one or more clones of cells. A "bad luck" type model assumes chance accumulation of mutations. The clonal expansion model assumes, on the other hand, that any mutation leading to partial loss of regulation of cell proliferation will give a selective advantage to the mutant. However, a number of experiments show that an...
