This, combined with the increasing age of the population, underscores the importance of identifying methods for risk reduction.

These guidelines should be considered when counselling patients in cancer prevention. In this article, colorectal, breast, and prostate cancers are highlighted, and nutritional recommendations for these cancers are presented.
