Health) - Canadian men who consume comparatively high amounts of dairy
products have an increased risk of testicular cancer, according to a new
- "Although testicular cancer is a relatively rare
lesion, accounting for only 1.1% of all malignant neoplasms in males in
Canada, it is the most common cancer among Canadian men 20 to 45 years
of age," Dr. Michael J. Garner, of the University of Ottawa, Ontario,
Canada, and others write in the International Journal of Cancer.
- The researchers obtained dietary information from 601
patients with testicular cancer and 744 similar men without cancer. They
used a 69-item food-frequency questionnaire to collect data on 17 food
groups, 15 nutrients, and 4 individual foods.
- Subjects who consumed high levels of dairy products had
an increased risk of testicular cancer. In particular, a high intake of
cheese was tied to an 87 percent higher likelihood of developing testicular
- Luncheon meat intake was also associated significantly
with testicular cancer risk in the total sample, Garner's team found.
- The investigators report that none of the nutrients were
linked the risk of testicular cancer, but carbohydrate intake was marginally
associated with one type of testicular cancer.
- "Our study adds significantly to the sparse literature
on dietary risk factors for testicular cancer," the researchers write.
- "Although the present study provides evidence of
increased risk in relation to the consumption of dairy products, the role
of diet in testicular cancer etiology requires further research,"
