Testicular Cancer

Cheese and Testicular Cancer

Can you figure out this remarkable riddle?

Why is it that nations with the lowest rates of testicular
and prostate cancers (Korea, Vietnam, Algeria, China) also
have the lowest rates of dairy consumption?

This may help you solve the riddle. Why is it that the
nations consuming the most cheese have the highest rates of
testicular cancer?

Still clueless? How about reading references from scientific
journals that government regulators and cancer scientists
are well aware of:

Testicular cancer is the most frequently diagnosed cancer
among North American males between the ages of 15 and 40.

In 2003, 7,500 Americans will be diagnosed with testicular
cancer, and 500 will die.

According to the Testicular Cancer Research Center
(, the nation with the highest rate of testicular
cancer is Denmark. Switzerland is number two. Denmark and
Switzerland also enjoy (?) the world's highest per capita
consumption of cheese.

The October 10, 2003 issue of the International Journal of
Cancer reveals that a high intake of cheese is associated
with an elevated risk of testicular cancer in Canadian

University of Ottawa scientist Michael J. Garner (Department
of Epidemiology and Community Medicine) compared the diets
of 601 men who were diagnosed with testicular cancer to 744

Food consumption data from seventeen food groups were
analyzed from a 69-item food-frequency questionnaire.
According to the scientists, the results suggest:

"...high dairy product intake, in particular high intake of
cheese (odds ratio [OR] = 1.87; 95% confidence interval [CI]
1.22-2.86; p-trend < 0.001), is associated with an elevated
risk of testicular cancer in Canadian males."

In 2002, the International Journal of Cancer (Ganmaa, et.
al. 98:262-267) reported that diet has an important
influence on testicular and prostate cancer risk.

The authors found:

"Cheese was found to be most closely correlated with the
incidence of testicular cancer. The incidence rate of
prostatic cancer was highest in the U.S. (101/100,000),
followed by Canada (65), Iceland (61) and Sweden (55). Korea
had the lowest incidence rate (0.9), followed by Vietnam
(1.2), Algeria (1.8) and China (1.9). Milk consumed between
1961 and 1990 was found to be most closely correlated with
prostatic cancer incidence (r = 0.71) and mortality (r =
