Testicular cancer.

Testicular cancer is a rare condition, accounting for approximately 1-1.5% of all cancers in men. It is the most common cancer affecting men in their 20s and 30s. Little is known about the exact cause of this disease, although numerous risk factors have been recognised. Treatment of testicular cancer has been extremely successful, with impressive cure rates reported. This is due to the excellent tumour response to chemotherapy and radiotherapy, and also to the diagnosis and follow-up regimes.
