Testicular cancer
Testicular cancer occurs when cells within the testis grow and divide abnormally.

Over the last 20 years, the incidence rate of testicular cancer has increased substantially (up 66%), however the mortality rate has been declining.
There were 675 new cases of testicular cancer in 2004, accounting for 0.7% of all cancers and 1.2% of cancers in males.
The lifetime risk of males developing testicular cancer before the age of 75 is 1 in 209.
21 males in Australia died of testicular cancer in 2005.
