Did you know?
- Testicular cancer is one of the rarest types of cancer, accounting for about 1% of cancer cases for men1
- The lifetime risk for men of developing testicular cancer is about 1 in 2501
- There are two main types of testicular cancer: germ cell tumors and stromal tumors; germ cell tumors account for about 95% of all testicular cancer cases2
What is testicular cancer?
Testicular cancer occurs when cells that aren't normal grow out of control in the testicles (testes). It is highly curable, especially when it is found early.3
Symptoms of testicular cancer4
The most common sign of testicular cancer is a painless lump in your testicle. Other symptoms include:
- Swelling or sudden fluid build-up in your scrotum
- A lump or swelling in either testicle
- A feeling of heaviness in your scrotum
- Dull ache in your groin or lower abdomen
- Pain or discomfort in your scrotum or a testicle
- A shrinking testicle (testicular atrophy)
What causes testicular cancer?
Testicular cancer develops when cells multiply faster than usual, eventually forming a lump or tumor. Researchers aren’t sure what causes cells to behave this way. Most men who get testicular cancer don’t have any risk factors.
Detecting testicular cancer
Most men find testicular cancer themselves by chance or during a self-exam. Or a provider may find it during a routine physical exam.
Because other problems can cause symptoms like those of testicular cancer, a provider may order tests to find out if there is another problem. These tests may include blood tests and imaging tests of the testicles such as an ultrasound or a computed tomography (CT) scan.3
If you have questions about any type of cancer contact your health care provider for advice and support.
