Simplified 2D scheme of DNA double chain with a proto-oncogenes (light gray) scattered all over the chain; b randomly distributed hits (lesions) in the DNA (red stars): when not repaired (or repaired wrongly) they can cause c mutations in oncogenes (dark gray), which can finally result in d the cancer transformation of the whole DNA chain (black) when mutated oncogenes reach the summarized effective volume threshold VT. See Table 1 for description of corresponding parameters (color figure online)
