Testicular cancer gives rise to few symptoms. Often, a feeling of heaviness or a change in size is the only symptom. A primary tumor in the testis can be very small, but still metastasize, for example, to the retroperitoneal space.
- Mild pain or heaviness in the testicle
- Sudden back pain may be due to a retroperitoneal lymph node tumor
- Coughing or dyspnea due to metastases in the lungs or mediastinum
- A defined lump in an otherwise normal testicle
- Change in consistency of the testicle. The cancerous testicle may be harder or softer than the contralateral testicle.
- Gynecomastia, due to production of estrogen-producing elements of the tumor
- Edema or thrombosis in the lower extremity due to compression of the vena cava
