Imagine seeing three men enjoying a day at the park. Greg is 22 years old, and he’s ready for a run around the lake. Greg’s 48-year-old father Vinay stays behind to talk with Greg’s 84-year-old grandfather, Fariq. Which of these three men is most likely to be diagnosed with testicular cancer? Greg, Vinay, or Fariq?
If you guessed it was Greg, you’re correct. While we might think of cancer as a disease that mostly affects us in our middle age and senior years, testicular cancer is different. According to the National Cancer Institute, it’s most common in men age 20 to 34.
Fortunately, testicular cancer is relatively rare. Around 1 in 250 men will be diagnosed with testicular cancer at some point in their lives. It’s also survivable, with a man’s risk of dying from testicular cancer at around 1 in 5,000. Early detection, however, remains a key element of successful treatment.
“Many types of testicular cancer can spread quickly and widely throughout the body,” said Dr. Gregory Britt, medical oncologist and hematologist with Rocky Mountain Cancer Centers (RMCC). “It’s essential to tell your doctor right away if you experience any symptoms – especially lumps.”
Where Most Testicular Cancers Begin
Testicular cancer begins in the testicles, the part of the male reproductive system that produces and stores sperm. The two organs hang below the penis in a skin sac called the scrotum. When cells begin to multiply out of control in one or both testicles, testicular cancer develops. Around 90% of testicular cancers begin in the germ cells, the parts of the testicles that make sperm. There are two types of germ cell cancers: seminomas and non-seminomas.
Semonoma: A Slow-Growing Cancer
Seminomas, which begin in the germ cells, grow slowly and are less likely to metastasize than other kinds of cancer. When tumors metastasize, they spread to other parts of your body. They become more challenging to treat than tumors still contained in one area of your body.
Classic seminomas make up around 95% of seminomas and affect men ages 25 to 45. A second subtype of this tumor, the spermatocytic seminoma, is more common in men 65 years old and older. This type is less likely to grow than a classic seminoma.
Nonseminoma Tumors Spread More Quickly
Like seminomas, nonseminoma tumors also begin in the germ cells, but they grow and spread more quickly than seminomas.
Nonseminomas are divided into four main subtypes:
- Choriocarcinoma – A very rare and fast-growing type of testicular cancer.
- Embryonal carcinoma – Another rare, fast-growing cancer.
- Teratoma – A tumor made up of bone, hair, or teeth tissue that can show up either in the testicles or elsewhere in the body. Mature teratomas rarely spread and can be surgically removed. Immature teratomas are more likely to spread. A third type, called a somatic-type malignancy, is the rarest teratoma.
- Yolk sac carcinoma – A common testicular cancer in children, especially in infants. When found in adults, it can be more difficult to treat than in children.
Benign Testicular Tumors
There are also two types of benign testicular tumors, which doctors will either remove or monitor. The first are stromal tumors that begin in the tissue that supports the testicles. They make up only 5% of adult testicular tumors, but they are four times common in children.
The second type, known as intratubular germ cell neoplasms, develop in the tubes where sperm cells form. They don’t usually spread unless they become cancerous. Also known as carcinomas in situ, doctors usually find this type of tumor during fertility testing. Some doctors opt to simply observe carcinomas in situ and do nothing unless it continues to grow.
Can You Avoid Getting Testicular Cancer?
Testicular cancer is hereditary, which means it is passed down from generation to generation. Because testicular cancer is genetic, it can’t be avoided. Additionally, many people with testicular cancer had no known risk factors at the time of diagnosis. That means that it’s typically not possible for young men to prevent or eliminate their risk of developing testicular cancer.
You may be at risk for testicular cancer if you are Caucasian, live in the U.S. or Europe, or have a family history of the disease. Men with an undescended testicle are at higher risk, as are men with an HIV infection or a prior testicular cancer diagnosis.
What Are the Symptoms of Testicular Cancer?
Men who notice symptoms of testicular cancer wait five months on average before checking in with their doctors. According to the Urology Care Foundation, a tumor can spread to other parts of your body, making it more difficult to treat and reducing your chance of survival.
Tell your doctor immediately if you feel any of these four signs of testicular cancer:
- A feeling of heaviness in the scrotum
- A dull ache or pain in your groin, testicle, or scrotum
- A painless lump or swelling in the testicle,
- Tenderness around your chest
How Long Can You Live with Testicular Cancer Without Treatment?
If left undetected, testicular cancer can spread to other parts of the body, such as the brain, lungs, and liver. When any type of cancer spreads throughout the body, including testicular cancer, it can cause complications that can become fatal in a matter of months, even with treatment.
What Are the Most Effective Treatments for Testicular Cancer?
Thankfully, effective treatments for most types of testicular cancer exist, especially when paired with early diagnosis. Doctors first determine what type of cancer it is, what stage it’s in, and whether it has spread. They order diagnostic scans, such as X-rays, CT scans, and MRIs. They might also use biopsies and blood tests.
Depending on their findings, doctors will recommend one or more of five different types of treatment:
- Chemotherapy – This involves using drugs that kill cancer cells or stop them from dividing. The drugs can be administered through mouth or by injection into veins or muscles
- High-dose chemotherapy with stem cell transplant – Because high-dose chemotherapy damages healthy cells, stem cell transplants are used to replace blood-forming cells.
- Radiation therapy – This involves targeting cancer cells with X-rays or other radiation
- Surgery – This involves the removal of the affected testicle and often some of the lymph nodes.
- Surveillance – In certain types of testicular cancer and carcinoma in situ of the testicle, doctors recommend holding off on treatment until it becomes necessary.
