Lumps or swelling on your testicles — or scrotal masses — are usually benign (not cancerous). But lumps can sometimes be a sign of another condition; in rare cases they may be a sign of testicular cancer. A doctor should examine your testicles and scrotum to find the cause of any lumps or swelling.
Symptoms of testicular cancer The most common symptom of testicular cancer is a painless lump on or in a testicle. Sometimes the testicle may become swollenor larger, without a lump. (It’s normal for one testicle to be slightly larger than the other, and for one to hang lower than the other.)
Epididymal cyst Epididymal cysts are very common and can happen at any age. They’re fluid-filled cysts (a tissue sac that can contain clear liquid or pus) that grow from the epididymis (a thin, coiled tube) of the testicle. Usually, they look like a pea-sized lump at the top of the testicle, but they can become larger.
A spermatocele (epididymal cyst) is a painless, fluid-filled cyst in the long, tightly coiled tube that lies above and behind each testicle (epididymis). The fluid in the cyst may contain sperm that are no longer alive. It feels like a smooth, firm lump in the scrotum on top of the testicle.
Five Common Signs of Testicular Cancer
An epididymis is located on the top of each testicle. Each epididymis is a tightly coiled tube. They store sperm created in each testicle until they’re mature, usually for about 60 to 80 days. The epididymis also absorbs extra fluid secreted by the testicle to help move sperm through the reproductive tract.
More common than testicular cancer is epididymitis, which is inflammation of the epididymis, a tubular structure next to the testicle where sperm mature.
Bumps that are cancerous are typically large, hard, painless to the touch and appear spontaneously. The mass will grow in size steadily over the weeks and months. Cancerous lumps that can be felt from the outside of your body can appear in the breast, testicle, or neck, but also in the arms and legs.
An epididymal cyst doesn’t require treatment unless it causes pain or discomfort. You may need surgery. During this procedure, your surgeon will remove the cyst and seal your scrotum with stitches that usually dissolve within 10 days.
When examining scrotal swellings, the key question is whether the lump is intra- or extra-testicular, as palpable intra-testicular lesions are highly likely (around 90%) to be malignant, whereas those lying outside the testis are usually benign.
They are often painless, but the affected testicle may sometimes ache or feel heavy. You may also experience some pain and discomfort if the cyst puts pressure on other structures in or around your testicle.
An epididymal cyst is a harmless fluid-filled growth on a man’s testicle (testis). They are quite common and don’t usually require treatment. Many men feel them and are concerned they have testicular cancer, but a doctor can usually tell the difference.
They can be felt, however. A spermatocele feels like a smooth, but separate, firm lump. The lump is found near the top of, or behind, a testicle. Spermatoceles are most likely to be discovered during your yearly physical when your doctor checks for any signs of a testicular growth.
Testicular cancer The lump will usually form on the front or side of a testicle. It will often feel hard, and the entire testicle may feel firmer than usual.
Hold the testicle between your thumbs and fingers with both hands and roll it gently between the fingers. Look and feel for any hard lumps or nodules (smooth rounded masses) or any change in the size, shape, or consistency of the testicles.
Typical symptoms are a painless swelling or lump in 1 of the testicles, or any change in shape or texture of the testicles. The swelling or lump can be about the size of a pea, but may be larger.
A painless lump or swelling on either testicle. If found early, a testicular tumor may be about the size of a pea or a marble, but it can grow much larger. Pain, discomfort, or numbness in a testicle or the scrotum, with or without swelling. Change in the way a testicle feels or a feeling of heaviness in the scrotum.
Most testicular cysts go away on their own with rest and scrotal support. However, if the cyst is enlarged or becomes infected, they may require surgical intervention. A cyst is a swelling that contains fluid, semisolid material or gaseous material.
The general 5-year survival rate for men with testicular cancer is 95%. This means that 95 men out of every 100 men diagnosed with testicular cancer will live at least 5 years after diagnosis. The survival rate is higher for people diagnosed with early-stage cancer and lower for those with later-stage cancer.
Testicular lumps are most often painless, although some do cause pain. They can also be movable or immovable. Some tumors may be smaller than a pea, while others can be larger than a marble. Many of the tumors will feel hard and rock-like.
Cancer that is more advanced can also spread to the bones or the liver. There are two main types of testicular cancer seminomas and nonseminomas. Seminomas tend to grow and spread more slowly than nonseminomas, which are more common, accounting for roughly 60 percent of all testicular cancers.
