Arguments supporting the “bad luck” hypothesis presented by C. Tomasetti and B. Vogelstein ((2015) Science, 347, 78-81) and A. V. Lichtenstein ((2017) Biochemistry (Moscow), 82, 75-80) are critically discussed. Those arguments are not sufficient for recognition of the “bad luck” hypothesis and the leading role of internal factors in spontaneous tumor development.
