**3. Conclusion**

The impact of nutrition and lifestyle on cancer development is evident. Still, there are many unanswered questions concerning the interactions among nutrition, environment and human genome. The existing and future knowledge should be used by public health professionals to promote cancer risk reduction on a population scale, especially in high risk subpopulations, as well as on the individual level. Further research and public health activities should be supported by health and government authorities.
