Testicular cancer is among the most common cancers in men between 20 and 45 years of age. A study from the University of Ottawa shows that a high intake of dairy products, particularly cheese, as well as baked goods and luncheon meats, may contribute to its development. Researchers collected data from 601 testicular cancer cases and 744 population-based controls from eight Canadian provinces between 1994 and 1997, examining nutrients, food groups, and particular foods using food-frequency questionnaires. It is suspected that female sex hormones found in dairy products could play a role.
