Quick answer

What is testicular cancer?

Testicular cancer mainly affects men aged 15 to 49 — most present with painless lump or swelling in a testicle. It is one of the most curable cancers — over 95% survive 10 years when treated promptly. See a GP within 2 weeks for any new lump or change in testicle — do not wait. Diagnosis by ultrasound and blood markers (AFP, HCG, LDH). Treatment — surgery to remove testicle (orchidectomy) plus chemotherapy or radiotherapy depending on type and stage.

Presentation

Classic:

  • painless hard lump within testis parenchyma
  • increasing size, heaviness

Less common:

  • paindo not reassure as infection without scan
  • acute hydrocele — ultrasound sees through

Advanced (rare if aware):

  • retroperitoneal massback ache
  • respiratory symptoms
  • gynaecomastia

Types

Germ cell (95%):

  • seminoma40s peak, radiosensitive, slow spread
  • non-seminomaembryonal, teratoma, yolk sac, choriocarcinomamixed common, AFP/HCG may rise

Non-germ cell rare — ** Leydig/Sertoli**

Diagnosis

  1. GP examinationintratesticular mass
  2. Scrotal ultrasoundhypoechoic lesiondo not biopsy testicle
  3. Tumour markersAFP, β-hCG, LDH
  4. Staging CTabdomen/pelvis/chest
  5. Radical inguinal orchidectomydiagnostic and therapeuticNOT transcrotal

Staging and treatment

Stage I — orchidectomy:

  • seminomasurveillance or carboplatin 1–2 cycles or radiotherapy
  • non-seminomasurveillance or adjuvant BEP 1 cycle if high-risk features

Stage II–III:

  • BEP chemotherapy3–4 cyclescures most metastatic
  • RPLND (retroperitoneal lymph node dissection) — selected residual mass post-chemo
  • salvage chemohigh-dose — refractory

Common questions

How do I check my testicles for cancer?
After warm bath or shower, roll each testicle between thumb and fingers — feel for hard lump or change from normal. Know what epididymis (soft tube behind) feels like — do not confuse. Any new lump — GP not watchful waiting. Monthly check not formally recommended but awareness helps.
What does testicular cancer feel like?
Usually firm painless lump on testicle itself — not usually on epididymis. Testicle may feel heavier or swollen. Some present with pain — less common. Advanced — back pain (retroperitoneal nodes), cough (lung mets), gynaecomastia (HCG-secreting tumour).
Is testicular cancer curable?
Yes — among highest cure rates of all cancers — over 95% 10-year survival overall. Even metastatic germ cell tumours often curable with BEP chemotherapy (bleomycin, etoposide, cisplatin). Early stage may need orchidectomy alone or plus surveillance.
Will I lose both testicles?
Usually only affected testicle removed (radical inguinal orchidectomy). Prosthetic testicle can be inserted. Remaining testicle often maintains testosterone and fertility. Chemotherapy may temporarily reduce fertility — sperm banking offered before treatment if wish children.
What are tumour markers in testicular cancer?
Blood tests AFP, beta-HCG, LDH — help diagnosis and monitor treatment — not screening tests for asymptomatic men. Seminoma may have normal markers — ultrasound and histology key.
