Old and New Carcinogens
In populations of developed countries, 60% of all cancer cases occur in people over 65 years of age, confirming that the older one gets, the greater is the risk of dying of cancer. Age, in this sense, is indeed the most important risk factor for cancer, as it would permit a disease that is genetically determined to appear late in life to manifest itself, and it certainly also extends the duration of exposure to the variety of factors that directly or indirectly increase the risk of developing a clinical cancer.
