Cancer incidence raises progressively during life span; it is estimated that by the year 2030 almost 70% of all neoplasms will occur in people over 65 years old. As carcinogenesis is a multistep, time-requiring process, it is expected that as people live longer they are more likely to develop cancer, and therefore, the prevalence of multiple primary malignancies (MPM) is destined to increase with age.
