Testicular Cancer

Updated: Feb 4

Testicular cancer is the most common malignancy in young adults



Which of the following statement about testicular cancer is NOT correct?

  • Treatment depends on tumour types: seminoma vs non-seminomaa

  • 5-year survival rate in England is higher than 95%

  • More than 50% of cases occur in men aged 60 or above

  • The cells of seminoma have a 'fried egg' appearance



32-year-old man presents with the feeling of a mass in the left testis. On examination, a painless, round and firm mass is palpated in the left testes with a size of 1.5 cm by 1 cm. The mass does not transilluminate with light.
29-year-old man presents with palpitations, heat intolerance, increased sweating, increased bowel movement and unintentional weight loss. On examination, a thyroid gland is normal. A hard nodule in the right testicle is palpable which does not transilluminate with light.

Key Points
  • Testicular cancer is the most common malignancy in young adults.

  • A painless testicular mass is an important sign. Although 10% of patients may present with painful swelling due to associated haemorrhage or infection.

  • 5-10% of patients may not present with a palpable mass but extra-testicular symptoms.

  • Ultrasound with colour Doppler is the first standard investigation.

  • Tumour markers include beta-HCG, AFP and LDH.

  • Biopsy is not advised due to the risk of spreading.

  • Radical inguinal orchiectomy is the initial treatment in most cases.

  • Prognosis is generally excellent
