Is Every Testicular Lump a Sign of Cancer?

No, not every lump you feel in the testicle means cancer. Many testicular lumps are benign and do not threaten a person’s health. However, some lumps can be a sign of testicular cancer, which is why evaluation by a urologist is essential. Timely diagnosis and treatment in these cases can be vital.

Testicular lumps can develop for different reasons. The most common include:

• Epididymal cyst (Epididymis): a fluid-filled sac that forms in the tube behind the testicle, the epididymis. These cysts are completely harmless and usually feel soft and movable when touched.

• Varicocele (Varicocele): swelling of the veins inside the scrotum, which can feel like a “bag of worms” and is usually seen on the left side.

• Hydrocele (Hydrocele): fluid buildup around the testicle that causes swelling and enlargement. In most cases, this condition is harmless and painless.

• Inflammation or infection (epididymitis or Epididymitis and orchitis or Orchitis): infection of the tube behind the testicle (epididymis) or of the testicle itself, usually accompanied by pain, redness, swelling, and sometimes fever.

• Testicular cancer: Testicular cancer usually appears as a hard, unusual, and often painless lump involving part or all of the testicle. It may sometimes be accompanied by a feeling of heaviness or mild pain.

Determining whether a lump inside the testicle is cancer requires several evaluations. The initial standard assessment includes physical examination and scrotal ultrasound, preferably Doppler ultrasound. If testicular cancer is suspected, further tests are also needed for a final diagnosis, such as blood tests for tumor markers (AFP, β-hCG, LDH) and pathology.

With timely diagnosis and treatment, testicular cancer has one of the highest successful treatment rates among all cancers; therefore, never delay seeing a doctor for evaluation of any change in your testicles.
