Results (Type of Cancer)
Seminoma
This is the most common type of testicular cancer. It usually develops and changes slowly and does not usually affect other areas of the body. This type of cancer is more common in men between the ages of 25-55, with a peak age of 35 years.
Non-Seminoma
This may contain several types of cancer, including one called teratoma. Non-seminoma is rarer and tends to affect men between the ages of 15-35, with a peak age of 25 years.
Both of these cancers are known as germ cell tumours. About 95% of testicular cancers are germ cell cancers. Germ means “seed” and these cancers are connected to the sperm making process.
Lymphoma
Some men suffer from another form of cancer called lymphoma. This is cancer of the lymphatic system. Four percent of men with lymphoma may also have testicular swelling. These men tend to be older, usually over 50.
