Cancers can be caused by changes in chromosomes that turn on oncogenes or turn off tumor suppressor genes. Most testicular cancer cells have extra copies of a part of chromosome 12 (called isochromosome 12p or i12p).
What gene is testicular cancer?
Variations in single genes is not common in testicular cancer but has been reported. The genes that are most commonly altered in germ cell tumors are KIT, TP53, KRAS/NRAS, and BRAF. KIT, KRAS/NRAS, and BRAF are oncogenes, which control and promote cell growth.
Can testicular cancer be genetic?
Almost half of the risk of developing testicular cancer comes from the DNA passed down from our parents, a new study reports. The research suggests genetic inheritance is much more important in testicular cancer than in most other cancer types, where genetics typically accounts for less than 20% of risk.
Can testicular cancer run in the family?
Having a father or brother with testicular cancer increases the risk that you will get it, too. But only a small number of testicular cancers occur in families. Most men with testicular cancer do not have a family history of the disease.

Does testicular cancer skip a generation?
While there is not a specific gene linked to testicular cancer, the disease is highly heritable and can be passed from generation to generation. In addition, the average age at diagnosis is two to three years younger than the general population if a first-degree relative has testicular cancer.
Can testicular cancer be cured permanently?
Can testicular cancer be cured? Testicular cancer is very curable. While a cancer diagnosis is always serious, the good news about testicular cancer is that it is treated successfully in 95% of cases. If treated early, the cure rate rises to 98%.
How long can you live with untreated testicular cancer?
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.
Can testicular cancer be prevented?
Many men with testicular cancer have no known risk factors. And some of the known risk factors, such as undescended testicles, white race, and a family history of the disease, can’t be changed. For these reasons, it’s not possible to prevent most cases of this disease at this time.
How do you self check yourself for testicular cancer?
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.
