What should you know about non-seminoma?

Non-seminoma is a germ cell tumour that may contain several tumour patterns and is treated according to its extent and marker results. It most often develops in the testicle, although germ cell tumours can occur elsewhere. Care commonly combines surgery, blood tests for tumour markers, imaging, and specialist follow-up.

A pathology report may describe embryonal carcinoma, yolk sac tumour, choriocarcinoma, teratoma, or a mixed tumour. The mixture matters because different components behave differently and influence treatment. Doctors also consider whether disease is limited to the testicle, has reached nearby structures, or is present elsewhere. The diagnosis is not determined by a lump alone.

The first treatment is often [Tumour Removal Surgery](/treatments/surgical-oncology/tumour-removal-surgery/) to remove the affected testicle through an incision in the groin and obtain a full pathology assessment. Depending on stage, marker behaviour, and pathology, the team may recommend surveillance, further surgery, or [Chemotherapy](/treatments/systemic-therapy/chemotherapy/). Discuss sperm banking before treatment if future fertility matters to you.

Seek urgent assessment for sudden severe testicular pain, rapid swelling, fever with scrotal pain, repeated vomiting, or pain after surgery that is worsening rather than settling. During chemotherapy, promptly report fever, breathing difficulty, uncontrolled vomiting, or signs of infection using the emergency instructions from your oncology team.

Ask which tumour components are present, what the marker results mean, what stage has been assigned, and why surveillance, surgery, or chemotherapy is being proposed. Ask about fertility preservation, prosthesis options, activity restrictions, and the schedule for scans and blood tests.
