Essential parameters in carcinogenesis are the genetic and extragenetic disposition of an individual, its exposure to chemical, physical or viral influences in the environment as well as its age as the time that is needed to induce cancer. Cancer prevention seems only possible by reducing the exposure. It will be discussed whether the increase in life expectancy has become so important during the past decades that it compensates all efforts of reducing the exposure.
致癌作用的基本参数包括个体的遗传和非遗传易感性、其在环境中接触化学、物理或病毒影响的情况，以及作为诱发癌症所需时间的年龄。似乎只有通过减少接触才能预防癌症。将讨论在过去几十年中预期寿命的增加是否变得如此重要，以至于它抵消了所有减少接触的努力。
