About testicular cancer
Testicular cancer is a rare cancer that usually occurs in men aged 20-40 years. It is the most common cancer in men between 15 and 49 years old.
More than 90 percent of testicular tumors are so-called germ cell tumors, which develop from cells that produce sperm. These tumors are divided into two main types: seminoma and non-seminoma.
Treatment for testicular cancer depends on the type of cancer and the extent of the disease. Some patients are followed up with only surgery, while others are offered additional treatment with chemotherapy and, in rare cases, radiation therapy.
