Testicular cancer accounts for only 1% of cancer in men, but it is the most common cancer found in men between the ages of 15 and 35 years old, and the incidence of this condition has been increasing over the last hundred years. Testicular cancer also seems to be more common in white men than in those of African descent.
Most cases of this cancer are found by testicular self-examination, often following a trauma or blow to the genital region.
The cancer is divided into two types: seminoma (30%) and nonseminoma (70%).
There's no known cause for testicular cancer. Below are some risk factors for developing testicular cancer:
- family history of testicular cancer
- previous cancer in one testicle
- tobacoo use
- undescended testis
Some studies suggest infertility as a risk factor for developing testicular cancer, but this is not yet proven. There is no association between testicular cancer and vasectomy, diet, or trauma.
