Testicular cancer accounts for 1% of all malignancies in males. However, it is the most frequently occurring solid tumour in men between the ages of 15 and 34 years. Testicular tumours have excellent cure rates, even in those with metastases, as they are extremely sensitive to chemotherapy and radiotherapy. Early diagnosis is, however, very important as treatment is more successful and less intensive, and long-term health consequences can be minimised.
