If you find a lump inside the scrotum, not arising from the skin of the scrotum itself, you should contact your GP immediately for further advice. To feel for testicular lumps, it is best to examine yourself when you are warm and relaxed (e.g. after a bath or shower). Stand in front of a mirror and hold each testicle in turn between your fingers. Feel the body of the testicle and all the structures attached to it.
If your GP is concerned that you could have testicular cancer, you may be referred urgently to the urology department using the fast-track (2-week wait) referral system.
Your GP should work through a recommended scheme of assessment for patients with a scrotal swelling. This will normally include some or all of the following:
Your GP will take a full history, paying particular attention to any possible trauma or infection of the testicles in the past. You should mention any previous operations on your testicles to your GP, especially surgery for an undescended testicle. Please tell your GP if you have had a vasectomy in the past.
A full physical examination will be performed, including examination of your scrotum, your abdomen and your lymph glands. Your blood pressure will normally be measured as part of this examination.
The actual tests performed will be left to your GP’s discretion. It is common to measure kidney function & liver function, and to check the blood cells for anaemia or other problems.
If your GP suspects testicular cancer, he/she may arrange some specific blood tests to measure tumour markers (alpha-fetoprotein, beta-human chorionic gonadotrophin, lactate dehydrogenase).
An ultrasound scan (pictured, showing a testicular tumour) will normally be arranged to assess exactly where the swelling is in relation to your testicle. Depending on the findings of the ultrasound scan, a CT scan of your abdomen & chest may also be arranged. This is normally fixed through the urology unit.
Swellings of the scrotum are usually cystic (fluid-filled), inflammatory or solid. Clinical examination and ultrasound scanning can usually differentiate between the possible causes.
These are the commonest swellings and are usually caused by a hydrocele (fluid around the testicle, pictured), a cyst in the epididymis (sperm-carrying mechanism) or varicose veins above the testicle (a varicocele). They are all benign and only require treatment if they cause significant symptoms.
Infection of the epididymis (sexually-acquired or secondary to a urinary infection), twisting of the testicle (torsion, usually in children) or infection of the testicle itself (e.g. due to mumps) are the commonest causes of inflammation.
Solid swellings include tuberculosis & syphilis (both very rare nowadays), a sperm granuloma or nodule (usually following a previous vasectomy), chronic inflammation of the epididymis. If the lump is within the testicle itself, it may be a testicular tumour.
A hernia arising in the groin can extend down towards the testicle but simple examination will reveal that the swelling does not arise from the scrotum itself. Urologists do not treat hernias and your GP may recommend referral to a hernia surgeon.
Hydrocele repair, excision of an epididymal cyst (pictured) and open surgery, laparoscopic surgery or radiological embolisation may be needed for significant symptoms from the swelling. Otherwise, no treatment is necessary.
Antibiotics are used for infection of the epididymis. Your GP may refer you to a urologist (if you are over 50 or have a urinary infection) or to a genitomedical clinic (if you are young or your infection may be sexually-acquired). Testicular involvement with mumps usually requires no specific treatment apart from painkillers. Suspected torsion of the testis requires emergency admission and immediate surgery.
If you are found to have testicular cancer, you will be referred urgently to the urology clinic. Following further investigations (see above), you will normally be advised to have the testicle removed as soon as possible. An artificial testicle can be inserted at the same time or at a later date. The need for further treatment (radiotherapy or chemotherapy) is determined by the pathology results, the results of your tumour marker blood tests & the findings on a CT scan. Once surgery has been arranged, you will referred to an oncologist for any further treatment and for long-term follow-up.
Tuberculosis and syphilis are rarely seen nowadays but are treated with appropriate antibiotics. Sperm granulomas in the epididymis may be removed if they are uncomfortable but they rarely require treatment.
