Although the exact causes of testicular cancer are not known, there are
certain factors that seem to increase the risk for testicular cancer.
These risk factors are:
A medical history of testicle problems:
These include a history of undescended testicle(s), abnormal
development of the testicles, Klinefelter's syndrome (a sex
chromosome disorder where the male hormones are produced in
low concentration, sterility, small testes, and development
of breasts can occur), or previous testicular cancer.
A family history of testicular cancer:
If a patient has a brother or father that had suffered from
testicular cancer, he is at an increased risk to develop testicular
Certain medical conditions:
- Multiple atypical nevi: Recent studies have suggested
that a medical condition characterized by multiple pigmented
spots or moles located on the back, chest, abdomen, and face,
increases the risk for testicular cancer.
- HIV infection: Some studies have shown that men infected
with HIV (human immunodeficiency virus) and particularly those
with AIDS, are at higher risk for developing testicular cancer.
Age: Testicular cancer is common among men between
15 and 40.
Race: Testicular cancer is more common among
the white population. For example, white Americans have five time
the risk of African-American men and more than twice the risk of Asian-American
men to develop testicular cancer.
Body size: A recent study conducted in Sweden
has suggested that tall, slim men are at a higher risk for developing
Social status: Testicular cancer seems to be
more common among men from wealthier social groups.
Profession: Testicular cancer seems to be more
common among men with a white-collar occupation. This risk might be
possible linked to a decreased level of physical exercises.
